Hey yall. I'm planning my first grow using CFL's. My parents caught me smoking weed and said they didn't care, as long as I didn't waste all my money on it... So I basically wanna grow for personal use and save some money My box is 3 feet long, 1.5 feet wide, and 2.5 feet in height. I'm not sure if passive or active intake is better. It would be great if someone with experience could tell me which option is better for my box. If I do passive, how big should the holes be and how many? I need all fans and holes to be on the right wall of the box, which is up against the wall so it's out of sight. Thanks! Here's some pics of the box- Imageshack - 1000679xn.jpg - Uploaded by mindrevolution Imageshack - 1000677f.jpg - Uploaded by mindrevolution
