18x18 isn't near big enough for one plant let alone 2 of them. My cab is a 6ft triangle and its almost not big enough for 3 plants. In the attached pics, there is only 1 plant in the cab.

There are 10 CFLs over the top and 10 dual tube 4ft flouro fixtures around the sides. I run the CFLs only till they get transplanted into 5 gal buckets, when they get put into flower, then I turn on the side lights also.
Mississippi Steve Reviewed by Mississippi Steve on . Got the green light, time to build, suggestions/advice please! I talked to my dad tonight and told him what I was wanting to do, which is grow in my room. While he doesn't smoke at all, he is fascinated by science and agreed to help me out with whatever he could. He also owns an electrical business and lighting store so thats a perk lol. Anyways, I have to hide it from my mom so I was thinking of building a box that is 18" x 18" x 60". I was thinking of running two strips of flouros down each side of the box and using CFL's at the top. Good idea or not Rating: 5
