yea, i wouldn't mind a tent either if i had a basement or a space to 'hide' it. But if we were to go with a a Cool cab with is what I'm looking into. It looks like a locker, filing cabinet with a lock and everything. I know that something like that could be built at a fraction of the cost. I am pretty mechanically inclined and could also design the grow space with 3d modeling software and calculate most of the heat transfer needed to keep it at room temp, ME graduate student. The problem is investing the money into the tooling require to make this box, Special hole saws that would probably only be used ONCE. I know that hole saws are not to expensive as is, but when you add up all the time, and costs of tooling to do it correctly, t just may not be as cost effective to it it ourself. These people probably already paid an engineer to design the box for optimum temperature etc. Those would be my assumptions i have no clue if they did or not.

which is the cool cab. Seems pretty interesting. i am probably going to go this route if i end up with a nice income tax check. Im living in apartment, so something done RIGHT is a must.
