Finally! After countless hours, it's ready to go. Will it work? I don't know yet. It's my first greenhouse and I don't know what to expect, especially with it being on a deck. I didn't have a great spot in the yard, so this was the next best place.
I built the subfloor with 2" foam board insulation between the studs, then I sandwiched a 1/2" sheet of foam board in between the plywood and studs.
To add height, I built the 6x8 harbor freight GH on top of 2x12s.
I used vinyl sheet flooring with a drain in the middle. I drilled a hole in one of the 2x12s to run an ext cord, then insulated the hole. I also modified the door. It was intended to slide, but I converted it to a knob-style, as I read the sliding door was prone to popping off the tracks.
I added one long shelf for starts (herbs, veggies, etc) and kept the rest of the space for the trees.
Total for everything you see was a little over $600. I have a radiant heater and I know I'll need a fan and probably some other things. I'll eventually remove the piece of 2x12 under the doorway and extend the length of the door for easier entry. We'll see how it goes...
