So my tent is in an unheated garage with a concrete floor. It's getting below freezing outside at night and really cold in the garage. Setting the plants on the bottom of the tent isn't good because they are basically sitting on cold concrete.
I put a floor on the bottom of my tent to keep the plants off of the cold concrete.
I didn't have any insulating material when I did this but I'm going to get some and use it as well. But for now it's better than the way it was.
Just a couple 8' 1" x 2" cut in half.
Two pieces of plywood 2' x 4' with the corners cut out so they fit. Insulating material should go in before these.
I covered it with another layer of plastic just because.
And threw the liner that came with the tent in.
Gotta have a heater. I said it was cold.
I'm still going to put some insulation down under the plywood and then probably a piece of that 1" 4' x 8' styrofoam sheeting or whatever it's called. I'm keeping the tent above 65 F but growing in fabric pots sitting on really cold ground is not good. This should solve that problem.
I was going to put in a heated floor this year but never got around to it. That's something I might do after Thanksgiving.
