Been talking the boss into letting me getting a greenhouse, thing is I don't want to fixed it on my grass, next best thing is to put 1/2" ply ontop of my deck then my greenhouse on the ply, everything would have to be grown in large pot or make a plywood trench down one side and along the back to form a L shape, and pots opposite the main trench, wood this work or be a waste of time/money.

I think your deck would rot with all the wet pots on top even if on plywood.
