At this point, I’ve put at at least 5 hoophouses and assisted in various parts of many others. I feel like I’ve got a pretty good grasp of the process, but I just stumbled on a handy publication of high tunnel construction tips (PDF) from UVM. If you’ve never put up a hoophouse, it spells it out pretty well. I definitely picked up a few things that I’ll do differently (and many that I’ll keep doing my way).
