U can make a light rig easy.Go to walmart and buy a light fixture. Cfls are great for that. i had the same idea but i never tried it out. but deff use tinfoil or white paint for the walls. hen ur plants start getting a little bit bigger u should transplant asap. and ventilation is needed as well. i stripped down a bathroom vent. but u can find a small fan or something. ur plants need fresh air. if u get the fan just cut a hole in the back of the box and pop it in there.
. u can see my setup. everything that i have is cheap stuff. u can make ur box nice, all u have to do is spend like 20-30 bucks. oh and i use a spraybotle for humidity. i go in there and spray pretty often. Good luck:rastasmoke:
