Propagation house redesign

Ok so last year I had to get up some sort of structure to keep my tomato seedlings under, and time was very short so I ended up going with a rebar structure like this

The problem was I had no way to keep the rebar hoops from moving side to side other than rope, as drilling and screwing wasn't possible. Now this structure got me through last spring but it was to short, the sides were so low I could only stand in the middle and the rebar would contort under pressure from the plastic being pulled to attach it to the sides, resulting in all sorts of issues. Well, lesson learned. Time for a new idea. After looking on the internet etc I decided to use a simple design and add a few of my own ideas. I am still building it but I wanted to start this thread as it is raining and I have time. Here is a link to the article I mostly followed, it has links to the info he used as well http://www.fiddleheadfarmers.com/fhf...eenhouse-plans

So far the new structure is looking great and I feel like for my region (hardly ever snows only occasional high winds) this will be plenty strong enough. It is 7.5 feet in the middle and there is adequate room at the sides as well. The gothic arch is easy on the eyes and very functional as well. I will next be adding purlins then hip boards to attach the plastic to. Then the end walls. Here it is so far.
