I'm not sure Sandi - The totes are taller than they are wide by a long shot. Three pots would probably be more and sufficient. I think I'd have to stagger four to fit them in the bottom. The good news is I can make the soil deeper and water less often....the bad news is I can only fit one, maybe two plants per box.
I do have the instructions and if I can figure out a way to scan them, I will gladly share!
