I have a big old farmhouse and I'm trying to figure out where to put my grow room. I have been using a closet in a spare bedroom with flouros. I recently purchased a 400w hps setup (hood with 6" inline air cooling) and I'm planning on going hydro. I could use the upstairs room - about 10x12 with a 9 ft ceiling, or build one in the basement. I'm leaning toward basement bcuz it's cool - temp consistant, and humidifier always running. NOW -- do I build a room in the corner? maybe a 5x5ft, OR do I use under the stairs? It's about a 3' x 6' x 8' tall at the high end -- I like this idea bcuz it's hidden in plain view. I'm just a little worried about heat in that space -- opinions are much appreciated!!
