We made mine with 2x4 and lattice panels, like I mentioned go to greenhouse and check my GH from miami, down here you have to protect the orchids from the rain. norma
Norma you mentioned you used plastic.. Can you tell me what kind ? Also has heat played a factor >?
How are you olding the plastic and the shade cloth together ? I am guessing you have the plastic on top and the shade cloth below. Have you had any problems with water puddling ontop ?
Ok I got the plastic from a co. at Homestead it's plastic for GH. I put the shade cloth and the plastic on top, you have to stretch both of them, I also got a black ribbon at HD to protect the plastic from braking. Did you visit the green house from miami? check that forum and check your private message. norma
