Love the greenhouse. Hoop houses are big now here in North Texas. I use low tunnels for my lettuce most of the time but this year has been so mild I've needed anything but a sheet. All the neighbors are getting my extras and loving every minute.
For all you folks interested in making one, go over to Johnny's Selected seeds and see their videos and instructions on how to do it. They sell the pole benders so you can bend your own hoop house and buy all the pipe locally. No expensive shipping that way.
Hope no one minds me promoting them but I really like those folks and they seem dedicated to helping folks grow food.
