Best place i've seen for the stuff so far was a trapdoor in the kitchen of my friends house leading to a room that goes under their house. It's insulated, kept warm, has a fan, and 4 gigantic plants. It was a great place to keep the stuff. My friends family then gave away all the cats that kept making kittens frequently. That's how i found the pot room, i walked into the kitchen and saw a bunch of kitties sleeping on top of a doormat. I went to pet one and found that the doormat was warm. No wonder the cats were sleeping right there in an otherwise pretty cold house. My friends dad showed me what was under the doormat the next day. It was one of those things where your eyes say holy **** rather than your mouth.
