How well is this room constructed? Is it actually sealed up?
Its sealed, all pt stock. Threw in some hard pack and stone dust for the bottom, used that new zip system plywood. The stuff you just need to tyvec, tape the seem and go. Then put a layer of ice and water all over and then before building we layed a tarp down, and another tarp will go over it before burring.
Its 7' 3'' x 6 foot, and 5' 9'' tall. So theres just enough room to get things done. We are getting all the insulation in before the roof goes on. Got r19 fiberglass insulation for in between the insulation, then covering everything with the 2'' foam insulation. Should'nt crush or cave in forawhile. But i need some ideas for venting. I was thinking of getting a bigger HPS, maybe a 1000w. I know those have the big 4-6'' duct vents. That could be our potential vent. Probably be a fan on the plants too. Using those little radiant space heaters.
Its going to be mad weird trying to find this thing in the snow
