First Legal Illinois outdoor grow, so do I put up this greenhouse or no?

I would think normally this is a no brainers, of course. Here is the real issue, I can't make it big enough so that the plants won't touch the sides. They are like 10' and like 4' wide. I never expected them to get this gigantic. They have pretty much filled the area there for them. So do I put this thing up and hope for no mold on the branches touching the walls. Or do I wait till next year and train them a lot harder so no wall touching??

When did you stick those in the ground? You want to build a greenhouse around them?
