I have a 4 ft wide, 14 ft tall closet, im putting a board horizontal 4 ft from the floor. I want to have a 2 sectioned closet grow, sealing the lower part from light for a veg chamber, and a flower on top. I have a lot of cfls, i might use for veg, and for flower i only have a 240w Blackstar LED. I don't want to cut a hole in the wall outward, so im worried about the heat of the closet, if i upgrade lights. The Blackstar leds are a little expensive, I'd rather buy a Hps or Mh. what are the best lighting options if I don't want it to overheat? I plan on having 6 plants in both the flower and the veg, and using a four 6 gallon homemade deep water culture buckets, three plants in each. Any advice is welcome!
