3 pages of ppl telling him not to grow in his parent's house and he's still intent.

scrap the snake cage idea - it won't work - it's hard enough keeping lights/temps/humidity under control for growing weed let along fucking with your poor snake's habitat - he'll bite you as payback for sure.

your best bet is to (as someone else stated) either use 2 Rubbermaid containers stacked on top of each other - if you can put this in your closet, even better...OR to convert a tallboy/dresser into a stealth cab, but this will take plenty of time and patience, which you seem to not possess.

good luck but i can feel numerous 'told you so's' coming on when it doesn't work, or worse - you get busted.
