this isnt the smartest idea, being they are heavy, takes 2 people to move them most of the time. But Newspaper boxes. The newspaper companies have 1000's of them in stock so if someone (like myself) steals one and turns it into a grill
which works great. But it is metal, yes, and that doesn mean some heat, the window in the front you can put some poster board over, and they are about 3' tall. But those have a huge empty spot at the top once you get it open. The coin retun slot acts for a great place to mount a switch or run your wires out of. and the door, when the coin mech. is taken out, will freely open so you can see your baby. I would only put 2 or 3 in there max to start out, but it is a very low profile grow box, could put it on your pack porch if needed.
Just an idea, dont get caught for something stupid liek that, and if you do plan on doing this try to find a newspaper rack not in front of a dunkin donuts. There are lots of porkers out there.
