Man I need a Hoop house like that. As soon as funds allow though!
I used dwv PVC and lumber for the frame. Screened the ends and lower sides for bugs. Reinforced the walls with chicken wire (to keep meth heads out and cats from scratching through the screen). All of which was pretty inexpensive.
The plastic, lock channel and wiggle wire were the most expensive parts at around $358.00 delivery included.
A person could buy all of the parts over time throughout the winter without spending much at one time. It doesn't need to be finished until June anyway. That's how I did it.
I hope everyone who wants to build one finds out that it's not that hard and costs less than you would think. And there is also the benefits of keeping your plants out of the rain. And it also limits the amount of exposure to pests.
I even covered my screened areas with weed barrier to keep most particulates (such as all the freaking hemp pollen!!! Jeeeezsch!) Out of the place and so far so good in "Parts Unknown!", no seeds to be seen forming.
However, if I could go back and do anything on the hoop house differently, it would be one thing- MAKE IT BIGGER!!!! Because it's so full now it gets hard to move around in there without getting sticky.
I mean, after walking through there, I could probably roll up quite a bit of hash off of my arms. I just don't like the idea of the taste of hash mixed in with burnt arm hair. Lol.
But anyway, build away my friends! Your plants will thank you for it. Just think of all the grass that wont get wasted by bud rot or broken and even killed by wind and hail damage. That alone could pay for a large part (if not all) of the build.
Good luck friend!
