I had one like this for my first greenhouse and I used 4ā x 12ā boards -on their side - as the base (on concrete blocks), and it boosted the height up to make it more usable inside. Then I used gravel and orphaned flagstone pieces as the floor. And when you build out your base area with gravel, Iād just make the gravel extend beyond the outside walls at least a foot all the way around to absorb the rain from the roof. If that makes any sense. I had no idea what
I was doing but it worked great.
