Getting ready to heat your greenhouse? Well, now is the time to either check your existing heater or to purchase a new one. Our top pick, the Southern Burner natural gas or propane greenhouse heater is going to have a price increase (the first time since 2008) on November 20th. So you want to be sure to order prior to that date. This is a super greenhouse heater that will fit under a bench and not take up any valuable floor space. It requires no electricity. The heater is all aluminum and stainless steel. They will keep the temperature at the top of the greenhouse within about 5 to 7 degrees of the floor heat. There is a vented and a non vented model available. The vented model is 25,000 BTu’s and will be adequate to heat most small hobby greenhouses. If you have a larger greenhouse you would simply add a heater or two. There is a formula to calculate how many BTu’s will be required to heat your greenhouse based on the size of your hothouse, the glazing type, the indoor and outdoor temperatures. Please be sure to follow this formula, or your heater may be too small to get your greenhouse to the desired indoor temperature. Plan ahead. Winter is headed our way. Don’t be left out in the cold this year!
Even though this picture was taken several years ago, it won’t be long before many of us will be seeing this as we look out our windows and long for summer. I know it is a few months yet, but now is the perfect time to prepare your greenhouse for winter. It is still warm enough that you can move any plants remaining inside the greenhouse to the outdoors. This will allow you to give your greenhouse a thorough cleaning. Be sure to use a mild disinfectant soap to clean with. Get the mold out of every nook and cranny. I know that we all keep our greenhouses relatively clean, but this is just something that happens with all of the humidity. Check any corners or places where there may be potential leaks and be sure to seal them up. Clean your benches if you have any. Repair or rework your flooring, depending on what you have in place there. Check all lighting and electrical systems. If need be, get a certified electrician in to help you with this. You can never be too safe. Same with your greenhouse heater. Whether you have electric, natural gas or propane, be sure to check your greenhouse heat source and be sure that it is properly connected with no leaks. Also, turn it on and make sure that it works. You may have to go out later in the evening as the temperatures drop to try this, but trust me, it is worth the time and effort to do this. In fact, I think that checking your heating system is the most important part of getting your greenhouse ready for winter. I cannot tell you how many times I have received panicked calls that it is going to freeze tonight and my heater won’t come on. There is just no way to get parts or a new heater to you fast enough. So, even though we are still enjoying summer time temperatures, think about the winter and your greenhouse now.
I know it is hard to image this. We are under a heat advisory today in Louisiana. But, now is the time to start preparing your greenhouse for winter. Really, I am serious. You should be doing a check for all of your systems and tightening up for the cold winter months ahead. This is a really good article covering what systems you should be looking after. Even though this was written for commercial greenhouse growers, most of the aspects still apply to the backyard greenhouse grower. Although, I am not sure that there are that many of us that have a back up generator on our home greenhouse.
