bigsmoke07 Reviewed by bigsmoke07 on . New Home, Empty Closet I finally bought my first house! One of the bedrooms has (what I think is) a perfect sized closet. It is 6' wide by 3.5' deep and about 8' tall. My initial idea is to split the closet into two 3' x 3' rooms with a 400w MH on one side and a 400w HPS on the other. There is already a shelf at about 6' that I can use to mount the lights on, and I can keep the ballasts/fans/ducting/etc on top. Id like to have 4 plants on each side. If the plants are under 5ft, I should be able to fit four 3-gallon Rating: 5
