Polycarbonate vs Polyfilm Greenhouse Covering

Polycarbonate vs Polyfilm Greenhouse Covering

Best Greenhouse Covering

Polycarbonate Sheets vs Single or Double Polyfilm

So, you have decided to build a greenhouse, but you are confused about which type of greenhouse covering would be best for you. Let’s take a look at some of the pluses and negatives of polycarbonate sheets and polyfilm coverings. We will discuss R value, installation, cost and  lifetime expectancy.




R Value

R value is defined as a materials ability to resist heat flow. The higher the R value, the less energy it will take to heat the same size space under equivalent conditions. This may or may not be a concern to you depending on how you are going to use a greenhouse.

Single Polyfilm

The most common single film used for greenhouses is clear 6 mil, 4 year covering. What this means is that the film is 6 mil thick and that the UV protection is warranted for up to 4 years. There are also some other types of film such as overwinter (this film is meant to last one year), white films (lower light transmission) , and reinforced polyfilm (with a rip stop cord).

The R value of single polyfilm is 0.87.  It is the least efficient of all of the greenhouse coverings we will discuss.

Installation can be done in several different ways. If you have a wood frame you can use batten tape and staple through the cover and the tape into your frame. If you have a wood frame or a metal frame you can use the base and wire system. The base is screwed to your frame and the cover is secured using a W or wiggle wire. This is a pretty simple installation, but you want to make sure that you do not try to do this on a windy day. You will need several people to do this depending on the size of the greenhouse.

The single polyfilm will be the least expensive of all of the coverings we will discuss.

This film should last you the 4 years that the UV covering is guaranteed for. The only issue with this covering is that you may get a tear. There is repair tape available for this. But, if you are not there and not able to fix a tear in a timely manner you may lose the entire cover. This is why some people will choose to go with the reinforced polyfilm over the clear 6 mil, 4 year. It has a rip stop cord that will keep a tear from spreading. That way you will be able to fix the tear no matter how soon you are able to get to it.

Double Polyfilm

You can do a double polyfilm greenhouse a couple of different ways. You can just buy 2 pieces of the film and attach them together. Or, the easiest way to do this is to buy a tube of the polyfilm. This is just a double layer that is already fastened together. The base and wire system is set up to hold up to 6 layers, so this is not an issue. You will also need a poly inflation fan kit to inflate the 2 layers. I have had some people mention that they think this makes the cover tighter and less susceptible to tears. I have no proof of this, but it does seem a logical conclusion.

The R value of double polyfilm is 1.7. This will save you 40% on the energy costs over a single layer of polyfilm.

The installation on this is done in the same manner as a single layer of polyfilm.

This film will basically be twice the cost of the single polyfilm, as you are basically just using a double layer of the same material. You will have the additional cost of the blower fan. These are typically around $200 or less, depending on the size of the greenhouse and the size of the motor needed.




This film may last a little bit longer than the single layer. As I stated earlier some claim that they inflation keeps the film from tearing as easily. The UV protection is rated for the same amount of time as the single polyfilm.

Polycarbonate Sheets

Polycarbonate is the greenhouse covering of my choice. It fits my needs the best of all of the materials. However, a lot of people don’t like it because of its appearance. It is a rigid plastic configured in much the same way as a piece of a cardboard box. It has a sheet on the outside, a sheet on the inside and a rib that runs through between the 2 sheets. The rib in polycarbonate will be straight vs the wavy rib in a cardboard box. This will distort your view. You will be able to see color, but you will not see form clearly. I use the example that you can see a green leaf and a red flower, but you will not be able to make out if it is a poinsettia, geranium, impatiens, etc. Of course the clear polyfilm is not exactly clear either. It will have a hazy type of appearance to it. If you want a clear glass like view, tempered glass is your only option.

Polycarbonate sheets are available in several different thicknesses. 8mm clear twinwall will have an R value of 1.8. 16mm clear triplewall will have an R value of 2.4. This will be the most efficient of the coverings we are discussing.

Installation of this material requires polycarbonate H profiles to join the sheets side by side and polycarbonate U channels to close off the ends. You will need more framing for this material vs polyfilm greenhouses. Typically polyfilm greenhouses will have 4′ or 6′ wide spaced bays. You can do the same with the polycarbonate, but you will need to run purlins between the rafters spaced according to your snow load needs. There are charts available to determine this. You can typically install this with 2 people as the sheets are not heavy and you install one 4′ wide or 6′ wide sheet at a time. You still do not want to try to install under windy conditions as the sheets can be caught by the wind and sail away.

This will be the most expensive of the coverings discussed in this article. But, it will be the longest lasting. Depending on the manufacturer polycarbonate sheets have between a 10 year and 20 year warranty on the UV. Most sheets also have a 10 year warranty on hail damage, so no need to worry about tears. The practical life expectancy of this material is 20 – 25 years.

Conclusion

When considering which of these materials to use to cover your greenhouse you should look at the initial cost, the cost to install, the cost to heat the greenhouse, and the life expectancy of the material. Once you have made these decisions you should be able to choose the best covering for your greenhouse with ease.

Growing Vertically

Growing Vertically

Growing Veggies Vertically

Growing Vegetables Vertically

Growing vertically is an excellent option when your space is limited and you are looking to increase your yield. There are some plants that naturally grow vertically, but there are also planters where you can “stack” your crops to save precious space. Let’s take a look at some of these.




Why Grow Vertically?

Well, there is the obvious point that I have already discussed about saving space. But, believe it or not there are other advantages to growing this way as well. Harvesting is easier. You do not have to bend down the entire time you are picking. Plants are healthier and give higher yields. There is greater air circulation around the roots and greater exposure to light.

Planters

Probably my first exposure to growing vertically was a strawberry tower. I used one of these about 30 years ago to grow my herbs. I totally enjoyed it. Today there are so many different type of vertical planters.

There are pouches with pockets sewn into them for individual plants, similar to a shoe holder. In fact I have even seen articles where people recycle and use their old shoe hangers for this. I think I would be careful with this, you want the holder to be of a breathable fabric. In my mind I see old style shoe holders made out of rigid plastic.

There are planters where it appears that pots have been strategically stacked on top of each other. A nice feature to look for in this type of planter is to see if there are any wheels or a cart below it. You may need to turn the container to get all of your plants the needed sunlight. If you are growing indoors you can probably set up your lights so that this is not a problem.

You can take an old set of stairs and add planter boxes to each step. This is a picture of a herb/flower garden combination I did a couple of years ago.

My Herb Garden

Pallets

Yet another way to recycle pallets. You can close off the back, sides and bottom of the pallets with landscape fabric. Put your soil between the exposed slats and plant your plants. I would leave this lay flat on the ground for a week or so allowing the plants to become rooted and established. That way they will not droop or potentially fall out when you hang the planter.




Growing with trellises, supports


There are some plants that want to grow vertically naturally. These would include tomatoes, beans, cucumbers, etc. You should supply them with support whether you are growing in a container or in the dirt. Make sure that your support is sturdy and securely fastened. You can purchase trellises or you can recycle and make your own. I have watched my husband go into our woods and come out with three sticks of the approximate same size. He placed them in a tepee type configuration and wound this together with rope. He says this is something he learned in the Boy Scouts. I am not sure of that, but I am sure that it was virtually free (the rope was laying around but it had been purchased at one point) and the plants loved it and did well.

If you are growing these types of plants in containers make sure that you have a large enough container for the job. There are some tomato planters out there that are all set up except for the dirt and the plant. Some of them even have lights so you can use them inside.

Hydroponic Systems

There are quite a few hydroponic systems out there that have multiple layers. These can be purchased, but I sure that they can be a pretty easy diy project as well. These systems are great because you get more food in less space as with all of the vertical systems. But, hydroponic systems have a tendency to have an increased yield over some other growing systems. Plus, crops will grow faster, harvesting is easier, you have less pests and disease with these systems. And you will have less problems with pets and wildlife with the systems, especially if you are growing them indoors.

Tips

Be sure to plant your bigger plants, or plants that tend to droop toward the bottom of “stacking planters”. You do not want these bigger plants hanging down and shading your smaller, more upright plants.

Use potting soil that is not as heavy as regular soil. You want to use the same type of soil as we recommend with any container gardening. You want a soil that will not dry out too quickly. You need something with peat moss, perlite, etc. Something fluffy.

Be very careful about how you set up your water. Of course with hydroponic systems or stacking systems watering is usually an integral part of the set up of the system. Let’s say that you are hanging pouches and planters from a fence wall or an exterior wall on your house. You want to make sure that you have the watering set up so that it does not lay on or run down the wall. You do not want to cause any water damage or leave water streaks on the surfaces.

Plant crops with similar needs such as having the same growth rate. This will ensure uniformity in your vertical garden. Also, consider plants with the same needs regarding sun vs shade. Make sure that your containers are not shaded by another structure if they are outside.

Make sure that you hanging planters are securely fastened. Also, check roots periodically to make sure that they are not growing into siding or just becoming a problem in general.

If you are growing inside be sure to set up your system in a sunny area, or supply them with the proper type of lighting. Options available are LED (light emitting diodes) lights, HID (high intensity discharge) lights and fluorescent lighting.

Conclusion

“I don’t have enough room to grow my own food” is definitely not an acceptable response anymore. Take advantage of one or a mix of these vertical growing systems to grow food for you and your family year round. Tammy

Growing Under Lights

Growing with Grow Lights

Growing Vegetables with Grow Lights

Do you want to grow vegetables and herbs indoors? Unless you are growing a few plants such as herbs on a sunny windowsill, you will definitely need lighting. If you do not use grow lights your plants will become leggy and spindly. They will not develop a healthy root system and let’s face it, they will probably never produce into the food you are looking for.

Trying to grow tomatoes in a greenhouse in the short winter days? You will need supplemental lighting. There are a lot of different lighting options available. Let’s take a look at them now.



Different types of lighting

There are basically 3 types of lamps available. They would be HID (high intensity discharge), LED’s (light emitting diodes) and fluorescent fixtures. There are a couple of sub categories in each of these categories.

HID Lighting

HID lamps are twice as efficient as fluorescent bulbs. They are available in several different sizes from 250 W to 1000W. If these are used as a primary light source a 250 W fixture will cover an area of 3′ x 3′. A 400 W covers 4′ x 4′, a 600 W covers 6′ x 6′ and a 1000W covers a 7′ x 7′ area. You should place your fixtures as close to your plant as possible without getting it too close. The HID lights put out a lot of heat. The best way is to put your hand under the light at the desired height. If it is not too hot for the back of your hand it will be OK for your plant. HID lights come with metal halide (MH)  or high pressure sodium (HPS) bulbs. The metal halide is for the vegetative or growth stage. It supplies a blue range of light that is similar to what we have in Spring. The high pressure sodium is for the fruiting or flowering stage. It supplies light in the red range. These systems come with a ballast. It used to be that we had to have one ballast for each type of bulb. But now there are switchable ballasts available that will work with either type of lamp.

Fluorescent Lighting

Historically fluorescent lights were thought of as to be used with seedlings or plants that did not require as much light. But, that has changed with the development of HO (high output) T5 lamps. These are only about 5/8″ in diameter. These high output lights will give twice as much light as the standard T5. They are able to produce enough light for larger or fruiting plants. Of course they will be more expensive than the standard fluorescent lamps. They are available in 2700K(yellow, red light)  for flowering or 6500K (full spectrum light) for plant growth. Fluorescent bulbs are also available in T 12, T8, T5 and compact fluorescent models. They are not as efficient and may be best left for seedlings and low light plants.

Fluorescent lamps have several benefits. They are lightweight, affordable and easy to assemble. They do not put out much heat at all. These lights should be placed within 4″ to 6″ of the top of the plant.

LED Lighting

LED lights have historically been very expensive and pretty much out of the range of the non commercial grower. But the prices have come down considerably in the last couple of years. The price on LED lights is still typically higher than the other types, but they will definitely cut down on the electric bill. They use half the electricity of HID and fluorescent lighting and will last up to 5 times as long. Most of these lights have a small built in fan which means they will run cooler.

There are full spectrum lights available where you can switch the growing mode. This is much the same concept as the switchable ballasts for the HID lighting. You should check the manufacturers specifications for coverage area and height to hang these fixtures. They are typically hung 18″ to 24″ over the plant.



How Long Should You Leave Your Lights On?

I know everyone hates this statement, but it is something you will need to experiment with. It depends on if you have any other light source and what type of plant you are growing. If you are using it as a primary light source growing inside I would recommend starting at 14 – 18 hours for the growth stage. Once you are fruiting or flowering you can cut this down to 12 hours.

If you are using the lights for supplemental lighting in a greenhouse you will not need them on during sunlight hours. The way we always did this was to have our lights come on 2 hours before sunrise and then turn them off. At night we would turn them on at dusk and leave them on for 2 hours. Of course this is all easiest to do with an automatic timer.

What can I grow using grow lights?

With the proper setup you can grow just about any crop under grow lights. One thing to take into consideration is what kind of space will you need. It is probably not practical for most of us to try and grow crops like corn or watermelon inside. A few examples that do well include tomatoes, lettuces, spinach, herbs, peas (will need to be trellised), bush green beans, bush cucumbers, broccoli, cauliflower, beets, carrots, radishes, etc. Keep in mind that you  must meet the same temperature requirements that these plants need outside. For example, you cannot grow cauliflower and broccoli in an 80 degree room. You cannot grow tomatoes in an unheated basement in the winter.

In Conclusion

Just because you don’t have a yard and it is the cold of winter does not mean that you cannot have fresh herbs and vegetables for dinner tonight. Set aside a little space and try growing some food indoors under lights.

Composting at Home | How to Compost

Turn Your Autumn Leaves into Compost

Compost your autumn leaves

Composting at Home | How to Compost

A lot of people wonder if composting is really worth their while. If done properly it really takes a minimal amount of effort. I am not saying you don’t have to work at it, but you don’t have to work at it hard. You just need to follow the “rules” and you will get an excellent product to use in your garden, your containers, or even your flower beds. Plus, let’s face it. None of us wants to contribute any more to the already overflowing landfills than we need to. Just think of it as doing your part to help Mother Nature.




Why Compost?

Over 1/3 of the materials in a landfill are compostable. Why are we throwing out these items that we can turn into the best amendment for our gardens? Do we think it is going to be too hard? I don’t know, let’s not over think it. Composting is simply the breakdown of organic matter. Nothing more, nothing less. Compost fuels plant growth, while restoring  previously depleted soil. It also helps to retain soil moisture and helps to hold off plant diseases.

What Will I Need to Compost?

There really is not much start up cost and you can get as fancy as you want. To start you can use a small roll of fence that you can purchase at any local lumber store or home store. You would also want to have a few posts to wrap the fence around to make your “bin”. Or, you can recycle pallets to make a compost pile. The most expensive, but probably the easiest way is to use a tumbling compost bin, but they will be the most expensive initially. There are also worm composters available. The worms do the breaking down of materials in these systems, no turning with them.

If you are doing any other method than the rotating bin or worms (vermicompost) you will need something to turn the pile with.  We had a special compost turning tool at one point, but a shovel or hoe would work just as well. A neat thing to have on hand is a compost thermometer. You can take the temperature of your compost pile and brag to all of your neighbors how hot your pile is. (I know, a little too geeky for some). This is also a nice tool to help troubleshoot as you rill read below. A really nice item to have is a decorative bin to place on your kitchen counter to collect scraps. You then just take this to your pile every day.

Other than that you need your browns and greens. I remember reading an article in a gardening magazine years ago. The author was telling you if you did not have enough garbage to use OPG (other peoples garbage). I guess some of your neighbors and friends would be willing to do this if you share at the end. I have also read about people going to produce departments and getting the produce that goes bad. The stores are usually glad to give you these unsalable items. That way it doesn’t have to go to complete waste.




What to Compost?

If you have checked into composting before you have probably seen the terms “green” and “brown”. These are referring to the 2 sets of materials that should be added in proper ratios to your compost pile. The green items supply the nitrogen and the brown items supply the carbon. You should use a ration of 1/3 green to 2/3 brown.

Greens:

Vegetable peelings

Grass Clippings

Egg Shells

Coffee Grounds

Browns:

Leaves

Sawdust

Pine Needles

Hay or Straw

I do not recommend using cheese or meat scraps for your compost pile, as these attract rodents. Leaves and larger items should be shredded prior to being placed in your compost bin. If you have too many leaves in the fall you can just save them to the side and add them to the compost pile as needed. Meanwhile they will be partially breaking down. Be sure not to add big clumps of any of the items you are putting in your pile. You want everything to be loose .

Maintaining your pile

Don’t leave food scraps at the top of your pile. Cover them with a layer of leaves or grass. This will help to deter pests (rodents, raccoons, etc)  that may want to get into your compost. You need to rotate every few weeks and add in more materials. You should be keeping your pile moist, not damp. Or, if you have purchased a rotating bin you should follow the instructions that have come with the bin. These are usually up on a stand and are easily rotated with a handle or simply by spinning the bin.

Troubleshooting Your Compost

Your compost pile should not smell. If it smells like rotten eggs or musty you need to add browns and aerate it (turn the pile). If your pile is not getting hot enough add more greens. This is where your compost thermometer comes in handy. Your pile should be getting to at least 150 degrees F if it is working properly. If your pile is too wet, add brown – cardboard, leaves or wood chips.




Bugs, etc in compost pile

If you have mites it means that your pile is too moist. You need to add your brown materials. You may see a white layer form over your compost pile. It is fungus and will aid in the process. It should be ignored. You may also see millipedes and potato bugs in your pile at times. There is no concern as they are just aiding in the process. If you have rodents you should make sure to “bury” food scraps below the surface of the compost pile so they are not quite as tempting to the animals.

When To Use Compost

Most people agree that the fall is the best time to add the compost into your garden soil. Cover it with some sort of mulch. That way it will have the entire winter to break down and become part of the garden bed. If this is not possible or you just don’t want to do it then you can add it about 2 weeks before you are ready to plant. Be sure to mix it into the soil good. Of course most of us are in a big hurry in the spring to get planted, so waiting until you can work the soil and then waiting 2 more weeks may be too much for some of us (pointing at myself).

Heating the greenhouse with compost

Did you know that you can use your compost pile to heat a greenhouse? You can put the compost pile directly in the greenhouse if you have space. Remember that they will get up to 150 degrees when working properly. Use your thermometer to check the temperature. If it is lower than 120 degrees you will need to aerate the pile.  Some people are concerned about having their compost bin inside the greenhouse due to the potential fire hazard. Plus, I have heard the complaint that the pile may smell. If you recall from earlier in this post, if you have a smell you need to fix your compost bin – something is wrong.

If you prefer to have your compost pile outside the greenhouse you can run water pipes through the compost pile to heat the water and then run the pipes into your greenhouse.

Conclusion

Composting is a win / win situation. It is good for your garden, good for the planet and good for your soul. Get busy composting!

Palram Greenhouses Review

Palram Greenhouses Review

Palram Greenhouse Review

Palram Greenhouse Review

We started selling greenhouses online in 2002. We started selling Palram Greenhouses online in 2003. It was a model called the Enthusiast. And I must say, everyone was very enthusiastic about this little greenhouse. It had a gambrel roof and was a 8′ x 8′ size. It had 4′ extensions that you could add on. The next model to surface was the Mini Pro. It was a 8′ x 10′ size. I am not quite sure why, but both of these models were discontinued. Snap and Grow Greenhouses were next to appear. We sold those for quite a few years up until 2014. They are still available, but we decided to not carry them anymore. It had nothing to do with the greenhouse, it was a “corporate” decision. We (Tom and I) just felt that we had too many greenhouse options available.

Enthusiast Greenhouse

MiniPro Greenhouse

MiniPro Greenhouse-no longer available

Features of Palram Greenhouses

They are sturdy! The first time I saw an Enthusiast was at a trade show in Ohio. I was walking down the aisle and all of a sudden there was a loud boom. I just about jumped out of my skin. There was an exhibitor in the Palram booth slamming a sledge hammer at this poor Enthusiast. It didn’t budge a bit. That was pretty impressive. Hey kids, don’t try this at home!!!

All of the Palram greenhouses are pretty much built with the same materials, there are just different configurations and options. Some of the models now have twinwall polycarbonate in the roof and/or sides. Even though the outside sheets of the twinwall are clear, the rib in the center of the sheets will distort your view. It will not be like looking through glass. The same single polycarbonate that was found in the Enthusiast will be in the rest of the models. You will get glass like clarity with this lightweight  panel with over 90% light transmission. The panels are flexible and you can bend them and twist them. Don’t let that fool you. It is very durable.

The frames are rust resistant aluminum and the greenhouses come with a 5 year warranty. I am very active in several online greenhouse forums. There are many people discussing their Snap and Grow greenhouses that are 8 – 10 years old. Let me tell you that Palram Greenhouse owners are very satisfied and loyal. Actually, the whole time we were selling these greenhouses we only had 2 issues. One was from a greenhouse that was in a tornado. That is just plain old bad luck. The other was a gentleman who just was not satisfied. We sold a lot of these greenhouses, so I guess one person is not too bad a record.

These have simple to use Smart Lock connectors. These greenhouses can be assembled easily by 2 people in 1 – 2 days. Step by step instructions are included with all greenhouses. You can accessorize your greenhouse with items such as plant hangers, shade cloths, an anchor kit, shelf kits, automatic openers for roof vents, benches, or a trellising kit. Most of the Palram Greenhouses can be made longer with the addition of extension kits.

Although the clear view clarity of the single polycarbonate panels is a nice feature, they will not supply you with as much insulation as other greenhouses. Although you can heat  them in the winter.  Depending on where you live and what temperatures you are want to achieve,  you may find that this is cost prohibitive. Of course there are solar methods you can use to retain some heat during the night hours. Also, some people will use bubble wrap to insulate the greenhouse more. If you are looking for a 4 season greenhouse I would consider the Glory with 10mm twinwall panels.

The Winter Greenhouse – To Heat or Not to Heat?

The winter greenhouse – to heat or not to heat? That is the question!!!

Should you heat your greenhouse in the winter?

We all want to use our greenhouses in the winter. But, it can be costly to heat them all winter long. For certain crops you will need the heat. Do you want to grow seasonal  winter crops without the cost of additional heating? Or, do you want to pay the heat bill to have tomatoes and peppers all winter long? That is the real question.



Did you know that a greenhouse will build up a lot of heat during the day? That is why you need a ventilation system in place. But, once the sun goes down the heat will begin to dissipate and disappear. In order to keep your greenhouse above the outside temperature at night you will need to have heating systems or other solar systems in place.

Solar Practices

You can keep some heat in your greenhouse at night by using a few solar practices. You can pull a solar blanket over the roof of the greenhouse to help keep any heat inside. These are on the inside of your greenhouse and are typically a heavy blanket that can be pulled at night.

Probably the most popular and easiest method is to use black containers filled with water. These will build up heat during the day and let off the built up heat slowly through the night. You can use gallon water jugs painted black or 55 gallon drums.

You can put a compost pile in your greenhouse. Although, I have heard quite a few people complain about the smell. If you have a properly balanced and properly functioning compost pile you should not have these odors. But, if you want to spend some time and money you can put your compost pile outside and pipe water through the pile (which will heat the water in the pipes) and through the greenhouse for heat.

Some people will use a layer of bubble wrap (yep, like what is used for packing in all the boxes you receive) to help add insulation to their greenhouse. They basically just line the interior with the bubble wrap to help keep the greenhouse a little bit warmer.

These methods will all give you supplemental heat, but none of them will give you a way to control what end temperature you require. To set the heat at let’s say 60 degrees, you will need a heater with a thermostat.



Heating systems

Greenhouse heating systems are available in electric, natural gas and propane. I much prefer the natural gas or propane. My top pick, and the heater that I use in all of my personal greenhouses, is the Southern Burner heater. I have used both the natural gas and the propane models. I find that they both function the same. These are great heaters because they require no electricity. They are the perfect size to fit under a greenhouse bench, thus staying out of the way and not using up valuable space. There is a vented and a non vented model. I personally have always used the non vented heater, but there are some locations in the US where this is a problem and against code. Even though it is called a non vented heater you still need to have a fresh air supply.

Max/ Min Thermometers

A relatively inexpensive, but very valuable tool is a max/min thermometer. These can go from low tech models to models where you can monitor the temperatures from inside your home. Some even have an alarm system set up with them if the temperature drops too low. These are valuable in both a heated and unheated greenhouse to help you troubleshoot any potential problems that you may have.

Crops You Can Grow in a Heated Greenhouse

You can grow just about anything that you can grow in your garden in the summer if you heat the greenhouse. Your night time temperature for tomatoes must be a minimum of 55 degrees. You can also grow peppers, squash, cucumbers, melons, beans, eggplant, corn, basil, tomatillos, etc.

Rules To Growing in an Unheated Greenhouse

If you are growing in an unheated winter greenhouse there are a few rules you should follow for the best harvest. You must be growing crops that are in season during the winter in your area. These cool weather crops include crops such as lettuce, spinach, chard, carrots, etc. Do NOT try to grow warm weather crops in an unheated winter greenhouse. If you are not sure of your growing seasons I would check with my local extension office to see if they have a free vegetable planting guide available. If you don’t know where they are just do a search for extension office “my town”.





Do not try to grow in containers. They will lose any heat they have retained rapidly. You should grow in  the ground or in raised beds.

Cut back on how much water you think the plants will need. Plants require a whole lot less water in the winter than they do in the summer. Only water when the ground is dry 1″ to 2″ below the surface.

Grow in “layers”. Add a cold frame or a mini hoop house inside the greenhouse. If you have electricity you can even add heat cables to the cold frames or under the mini hoop house. I always like to use heat cables in  my personal cold frames. I  find that it gives a higher yield earlier. Just be sure that you check these in the morning. Depending on your location and your weather your cold frame or mini hoop house made need to be opened during the day and closed at night.

Crops You Can Grow in an Unheated Greenhouse

You can typically grow lettuce, spinach, radishes, carrots, beets, turnips, kohlrabi, broccoli, cabbage, bok choi, chard, greens, mustard greens, kale, chives, chinese cabbage, english peas, and cilantro (may require a double layer growing system such as the cold frame).

In Conclusion

To heat or not to heat? Well, that is really your decision and should be based on how much money you want to spend for winter heat and what crops you want to grow. Whichever way you go, fresh veggies year round can’t be beat! Enjoy!

How To Grow Mushrooms

How To Grow Mushrooms

Are you concerned about the quality of mushrooms you are buying in the grocery store? Do you wish you had healthier alternatives? Why not grow your own? It is not all that complicated if you have the knowledge of the requirements of the plants and a few simple tools.

What are mushrooms?

Mushrooms are a fungus. They are low in calories and carbohydrates. They are a great source of B vitamins, trace minerals, fiber and even protein. They are high in antioxidants and they have anti inflammatory properties. They have also been linked to fighting cancer and supporting heart health. OK, and if all that is not enough, they are pretty darn tasty too.




Why should I grow my own?

I confess that I used to buy jarred mushrooms for when I was really lazy. One day, several years back, I took the time to read the label and found that they were not from the USA. That was the end of my jarred mushrooms. But, even if you are purchasing fresh mushrooms you do not know what pesticides may have been used. Due to the nature of the mushroom they absorb a lot of what they come in contact with. I don’t really want all of that. Plus, as an avid, long time gardener, I know the joy of harvesting your own crops. Not to mention the peace of mind that comes with it.

What do you need to grow mushrooms?

You will need either mushroom spores or spawn. The spawn are much easier to handle for a first time project. As you progress you may even learn how to harvest your own spores, but that is not something that you would want to take on as a new mushroom farmer. You need a growing area. You will want an area where you can cut the light off and keep the temperature at a pretty constant temperature. A basement, a spare room, anything of that sort. I remember talking to a man at a garden show years ago. He told me he had grown mushrooms in his hallway for years. You will need nutrient rich soil and a substrate. Materials such as straw, compost, wood chips, sawdust, newspaper, cardboard or coffee grounds are excellent materials for the substrate. You will also need boiling hot water and temperature and humidity controllers.

What kind of mushroom should I grow?

Oyster , shitake and button mushrooms are probably the easiest to grow. There are so many other beautiful, colorful and I am sure tasty varieties to try that are available as spawn. These may take longer to grow.

How do I grow them?

Some of the spawn that are available are meant to be inoculated onto stumps or logs. These take up to a year or more to produce. These are the exception. Most mushrooms will produce between 1 – 3 months depending on the size of mushroom you want. You basically sterilize your substrate which has been placed over your soil. You then inoculate the spawn or spores. Make sure to keep your temperature at the desired level for your species. At this point you will be misting the spawn 1 or 2 times per day. Once you see mycelia – which is a fungal version of roots, you will cut the watering down to once a day. The main thing is to keep out of light and drafts. For detailed instructions see Mushroom Growing 4 You.

If you purchase a kit you should follow the instructions with the kit. You harvest by cutting with a sharp knife. Once you cut the mushroom another may appear again in the same space. But, to ensure a constant supply of mushrooms you should plant a couple of weeks apart. If you are using a large enough growing bed you may just be able to place your spawn in different areas of the bed a couple of weeks apart.




Growing with Mushroom Kits

These have had pretty much all of the guess work taken out of them. Most of the kits are as simple as open and water. Some will even give you mushrooms in as little as 10 days. This is a great gardening project for a child. With the short turnaround time they will not tend to lose as much interest as with crops that take longer.

Can I make money growing mushrooms?

Absolutely. But, as with any farming operation, you will need to research your local market first. Visit your local farmers market and see if anyone is selling mushrooms. Ask the vendors if they ever get requests for them. Go visit your local chefs and see if they would be interested in purchasing them. If you have small local grocery stores you may be able to work with them. I am finding more and more that even the big grocery stores are trying to source fresh food locally. If you have the demand do not start out too large, especially if you have never grown mushrooms before. The best feature of growing these is that you do not need to invest in expensive equipment to get started. You will need your items as listed above, but they are not high dollar or hard to find items.

Conclusion

We are all concerned about the quality of our food. That is a given. But, there is nothing more satisfying than growing your own food. Mushrooms are an ideal crop because they don’t require a lot of room or hard to obtain special growing conditions. Try your hand at growing mushrooms today. I think you will be pleasantly rewarded for your efforts.

What’s All The Hype About Hypertufa?

DIY Hypertufa containers and garden art

What’s all the hype about hypertufa?

Have you been seeing “hypertufa” a lot lately? Are you unsure of what it really is? Would you like to learn how to make your own hypertufa projects? Then read on.

What is hypertufa?

Hypertufa is an excellent diy project. It is a long lasting and beautiful substitute for tufa. Next question – what in the world is tufa? It is a natural volcanic rock. Making hypertufa is the art of making decorative or functional garden items from a blend of cement, peat moss (coir can be substituted under certain circumstance), sand, perlite or vermiculite, and water. There are about as many hypertufa formulas as there are hypertufa crafters. You can vary your recipe and the amount of each ingredient added to meet the needs of your project.




Why hypertufa?

Why not? It is an excellent substitute for heavier concrete planters. It is lightweight, it can be hand molded, sculpted, carved,  and you can add decorative mosaic pieces or color to it. It is long lasting and will not freeze if it is cured properly. When the peat moss breaks down or decomposes it will leave pits and crevices making a natural looking pot. It is a porous material that is conducive to plant growth. Plus, the fact that your creative juices can flow and you can make a truly one of a kind, this is my creation, piece is just the topping on the cake. A small beginners project would be an excellent start to a child’s journey into hypertufa. They will love it. It has been compared to making mud pies! Don’t forget to wear old clothes.

What can I make?

You can make just about anything you can imagine. To name a few you can make spheres, steeping stones, birdbaths, planters, trough planters, garden art, hypertufa leaves, stepping stones, garden lanterns, birdbaths, etc. I am sure you can think of a few more projects.

What tools do I need?

You can probably scavenge most of the tools you need from your household items. You need mixing utensils (gloved hands work well for this) , a mixing container (maybe a wheelbarrow or smaller depending on your project), and molds. Some examples of molds are dish pans, oil pans, boxes, boxes  you make, just about anything you can think of.

Can I find all of the materials locally?

You should be able to locate all of the materials that you need to do a hypertufa project. Portland cement is readily available at the big box stores. Please note: this is not concrete. It is an ingredient in concrete. Portland cement comes in white or gray. You will use the white when you are adding color or if you want a granite look. The gray will be used for all other projects. You should also be able to source all of the other items at big box stores or at local nurseries. We prefer to support the local nurseries whenever we can.




What formula is the best for my project?

Some of this will depend on how you are going to form your final art. If you are a beginner you are going to use the simplest and easiest to work with formula available. No need to burn yourself out with a tough project the first time. Do something small and attainable. Master this and then move on to your next formula. There are formulas that give added strength, that have wire mesh for even more strength, that will make the material easy to carve, that will make the material lighter weight, etc.

What is the most important part of this project?

Well, I would have to say that the artistic decisions are the most important part, but in all actuality it is the curing. A properly cured project will last for years through harsh environments. An improperly cured project may fail before you expect it to. Of course some of this is like gardening. There are “hard, fast” rules that we all have to follow. Then there are the “wonder what will happen if I try this” moments. Not all gardens in all areas grow in the same manner. I have even read about microenvironments where the conditions vary from neighbor to neighbor. But, you will reach a point when you know the proper feel to cured hypertufa. The secret is to cure it slowly in a moist environment. The first part of curing is done in a plastic bag for 2 – 4 days. You will not be able to scratch the surface of the tufa. At that point you can unmold it. You will leave it in the bag unmolded up to a month or more. The project is completed when it sounds hollow when tapped. The final step is leaching out the lime that could be hazardous to your plants. A simple method is to soak it in fresh water (that is changed every day) for 3 days. Next step, planting in your vessel or placing your garden art in the appropriate place.




Looking for extra income?

Hypertufa planters, garden art, etc are in high demand. This is due to the many beautiful configurations that are designed and made. Also, don’t forget the lightweight, durable, and porous attributes that make this a much desired item. They sell great at yard sales, garden shows, flea markets, etc. This is a great way to get your children involved in creation and the art of making money as well.

OK, did I entice you?

Hopefully by this point you are thinking, I have a great spot for a hypertufa sphere. Want to learn how to do this? Check out this thorough informational book. Everything you need to know for a successful project is covered in this 100 page book.

Build Your Own Polyfilm Hoop House Greenhouse

Build Your Own Polyfilm Hoop House Greenhouse

Build Your Own Polyfilm Hoop House Greenhouse

There are a lot of reasons to build your own polyfilm greenhouse rather than buying a kit. You may have a special feature or size that you cannot find in a kit. Maybe you have some materials you can recycle. Or, you may just enjoy letting your creative juices flow and making your greenhouse from your own hands with your own design. There are a few basic steps you should follow making decisions regarding your greenhouse whether you are using a kit or building your own design.



Location:

You should pick the proper location for your greenhouse. This should be a clear, sunny spot on a nice level location. The ends of the greenhouse should be situated facing north and south.

Size:

This is always a major decision when getting a greenhouse. The rule of thumb is – go one size larger than you think you will need. We are, after all collectors and experimenters. We may see the perfect plant at a sale that we just can’t resist. Or, we may find our next best go to variety of tomato or other vegetable that we just have to grow this year. Try to either mark out on your land how you think your plants will be arranged, or do this on a piece of paper. Consider whether you will be having raised beds, containers or hydroponic systems.

Framing Materials:

Will you build your frame using pvc pipe or galvanized pipe?

PVC –

If you are using pvc pipe you should use schedule 40 pipe. The simple way to do this is to place a 3′ piece of rebar (sticking out of the ground 12″) where the ends of the hoops will be. Two people are needed for the next step. Place each end of the pipe over the rebar and make your hoop. Your hoops should be placed 4′ to 6′ apart. You will need to use purlins for your frame as well. These are what hold the pvc hoops together. If you skip the purlins you will just have a row of hoops with a cover over them. There is not much structure to this. A minimum of 3 runs of purlins should be used running from one end of the greenhouse to the other. Usually you have one right in the center of the greenhouse with one run along each side where the greenhouse is starting to “bow”. You can use special pvc fittings to tie these together. Most people will use treated lumber to run along the bottom of the long sides of the frames. You can frame out your ends with pvc or with wood. You can build your own door using pvc for framing, or use a purchased (or recycled) wood door. Please note: This style of greenhouse should not be used in high snow load areas. There is a tendency for this type of structure to collapse under heavy snow loads.

Galvanized Pipe –

There are pipe benders available to make specific width of greenhouse bows. Choose the appropriate one for your needs. You will install ground pipe 2′ into the ground with 2′ above the ground. Install your hoops at 4′ or 6′ increments. Install your purlins. You can use a board at the bottom of the sidewalls. The process is basically the same as with the pvc pipe, just different materials. The end walls can be framed out of wood. Although this structure will obviously not have any snow or wind rating, it will be stronger than the pvc frame.

Choosing Your Cover :

There are several different types of covers. The worst choice you could make is going to the box store and buying a roll of film off the shelf. This is great film, but it is just not designed to be used for a greenhouse. There is no UV protection on it. The sun is what breaks down the material. You will be lucky to get one year out of this type of covering. The most commonly used material is a 6 mil, 4 year greenhouse polyfilm. This means that the film is 6 mil thick with a UV covering rated for 4 years. There is also a reinforced polyfilm covering. It has a rip stop feature that will stop a tear once it hits the reinforced cording.

Single vs Double Cover:

You can use either one layer of polyfilm, or a double layer of polyfilm. For the double polyfilm a blower will add air between the layers increasing the insulation factor of the covering. Most people even say that they feel that this makes the film more resistant to tears because it makes it tighter.



Fastening Your Cover:

There are several ways to fasten your cover to the greenhouse. The piece over the top should go from ground to ground.

Batten Tape-

You can use batten tape to fasten the film to the bottom boards. You will place the batten tape over top of the cover and staple through the tape and the cover. Be sure to have your film tight, but not to taught. An overstretched cover has a tendency to tear.

Base and Wiggle Wire

wiggle wire and base for polyfilm greenhouse

This is a 2 part system consisting of a metal base (kind of like a c configuration) with a w wire or wiggle wire. You can fasten the base to your side boards. The base will also bend enough that you can fasten it to your end walls. Pull the cover over top of the base and work the “w” wire in with a wiggle motion. This is a good secure fastening system and will work well with a double polyfilm covering.

Ventilation:

greenhouse ventilation system

Don’t forget to address ventilation. Most people will frame out an opening in the front walls and back walls for exhaust fans or intake shutters. The exhaust fan should go up high in the back wall with the intake shutters down low on the opposite walls. These are usually wired to one thermostat so that they come on at the same time. You may choose to go more low tech and use a roll up curtain along both side walls.These are also available as solar powered systems which require no electricity.



Heater:

southern burner non vented heater

There are times when a heater is not necessary for a hoop house. It depends on the type of crops you are growing and what time of year you are trying to grow them. Cole crops can be grown in hoop houses in the winter often without any supplemental heat at all. On the other hand, if you are trying to grow tomatoes or peppers in the winter you will need supplemental heating.

Conclusion:

Building your own polyfilm greenhouse will be a rewarding experience not only while you are building it, but also while you are using it to grow your own crops.
