My husband and I built a greenhouse last year, and he wanted it to have a proper raised floor rather than being on the ground so that the structure would be more solid. When the temps dropped, I realized this meant it was always as cold inside as outside. Was this the wrong thing by to do, and can we mitigate it by putting some kind of flooring down that still allows drainage but keeps cool air out? I was thinking about those thick foam mats? Thanks in advance!

Great for extra airflow in the summertime, not so much for the same reason in the winter. My initial thought was to get some sheets of foam to put on the floor, but that would stop your drainage. Off the top of my head, if it were me I’d get some sheets of foam insulation and make panels to go around the “foundation” , bury them a few inches in the ground and nice and tight to the top of the floor system. Then you can pop them off in the summertime.
A raised floor is not something you want in a greenhouse. The ground is a heat source in the winter- though not much of one. If it’s any consolation, unheated greenhouses are pretty much always within a couple degrees of ambient outside temperature when the sun is down.
you could always pack fallen leaves or straw around the base of the structure to help insulate it. maybe a low hedge too.
