bottom floor has not great air quality, its dark, damp and animal shit. smells pretty farm down there. dont want to pull that upstairs. its cold down there in may/June but by now its warming up not much better than outside.
DIY swamp cooler is not a bad idea. i might play with that at some point. i plan to put wheels and welding cords on the two smaller 36" fans to make them portable. HF soaker hose?
