I wouldn't recommend tinfoil. It's electrically conductive and a fire hazard, creates hot spots, tears and wrinkles easily, traps heat, etc. Flat white paint is the most reflective.

Get some CFL's for lighting. All the answers are here:

Yes, the plants need ventilation... as explained in my first post's link about grow rooms. With cfl's, you can probably get away with a bathroom/kitchen wall-mount fan for exhaust at the top, and a simple open hole at the bottom for a passive intake. Then an oscillating fan blowing air around the room and making the plants sway a little.

You can make a DIY carbon scrubber for smell control. More instructions online if you search for it.

Google : your topic site:boards.cannabis.com and you can find a lot of answers. But again, most of the info is already here in the stickies at the top of each section.
bigtopsfinn Reviewed by bigtopsfinn on . Help Me With My First Growbox I need help constructing a growbox, preferrably one that is pretty cheap lol. I've read tons of shit about it, and still confused on many things. Can anyone give me a list of things I will need, and how to set it up? Any help is appreciated. Rating: 5
