When you click on
Specifications it says "Coroplast" right at the top.
I didn't read further.
"6 year reinforced clear plastic sheeting." Do you mean 6-mil? I searched for the former and got the latter. I hadn't heard of reinforced sheeting, but I am unsure how it would help. I bought the thickest sheeting Home Depot had. I believe that it was 6-mil and it disintegrated in the sun.
With reinforcement I would end up with a net with little bits of plastic stuck on it.
By the way, how come I see many green greenhouses. Sure, it is in the name, but isn't green exactly the worst color--except for black?
