Now we're going to talk about the "skin" of the hoophouse, possibly the most important part. Now a lot of aspiring farmers and gardeners have made a little practice hoophouse, or a cold frame out of hardware store plastic, not a good idea. The stuff degrades in the ultraviolet light and you'll be rebuilding within the year. So for a professional quality hoophouse, or any backyard hoophouse, you really want to invest in the greenhouse quality, ultraviolet treated, six millimeter plastic. It's not cheap, but it's worth every penny. Nowadays they've come out with a new generation of extra special hi-tech plastic, so you can do some research. They have additives now that will inhibit the radiant heat loss so you can be even warmer at night. And they also have additives that will prevent condensation. Condensation, of course, causes drips, and drips, of course, cause disease and rot on your plants. Okay, so you've got your plastic, and here is your next option, whether to go one layer or two layers. This, you can see, is an inflated double-layer hoophouse. There's two layers of plastic, and this tiny little fan inflates the envelope in between the two layers. This little three volt fan does all the work, keeping a nice envelope of air. Now the advantage of the inflated hoophouse is that, better insulation of course, and also, if your plastic isn't riffling and ruffling in the breeze and wind all the time, you have less breakdown and the stuff will last years longer. This plastic is guaranteed for four years, and I've been told if you take good care of it, it might double that expectancy.
