Hi all this looks like an awsome site!!!

I just built my first greenhouse!I never looked into it just built it!!!I used tempered glass slabs from patio door sets.I cut the thermol units in half and ended up with 4 slabs from one door set.I built frames around the glass pieces.I then built a plywood deck 18 inches off the ground as if i were building a deck.put the walls up then the gable roof witch is glass also.What im asking is if this is going to be practial for growing?Also what you folks would recomend i go buy to get satrted?as far as shade cloth goes can I use used shade cloth from my friends Ginsin farm?also what about heat and ventilation?

as you can see so many questions so little answers.So please help!!!!

Thanks everyone
