Ventilating a Homemade Polyfilm Greenhouse

 

Polyfilm Hoop House

Are you building a homemade polyfim greenhouse, but are unsure about how to ventilate it? Here are a couple of solutions for you. You can see that this greenhouse has roll up sides, an option which is readily available, but can be costly. We have 2 options available that insert directly into your polyfilm covering without any additional framing. They use the channel base and wiggle wire to insert directly into the greenhouse covering. You simply cut the film and install these accessories directly into the film covering without any additional framing.

The first option is a solar powered greenhouse shutter. This has louvers and a wax cylinder powered opener. It will open when it is warm and close when it is cool automatically. They are available in 6 different sizes. If you would like to use this on another type of greenhouse such as polycarbonate, we can remove the base channel and you can insert this directly into a wood framed opening.

The second way to do this is with a solar powered roof vent. This is a lightweight polycarbonate vent. It weighs less than 10 pounds, but you get all of the benefits of the durable polycarbonate covering.  It also has the was cylinder powered opener that will automatically open and shut the vent as the temperature requires. To install this you simply cut the polyfilm and install it directly into the greenhouse covering.

A lot of people prefer to build their own greenhouses rather than purchase a kit. With these 2 ventilation options, there is no reason not to build your own polyfilm  greenhouse.




Prepare Your Greenhouse For Winter

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.
