I totally understand that cfls need to be closer to the plant than the other options avail but my problem deals with the fact that i lost my last plant due to keeping it too close. So my question is, how do i keep a cfl rack close to the plant and not burn it, but not too far away to promote stretching? is this just "the art" of it, or is there a good tool/technique used to diagnose the distance (i.e. read the plant, distance temps, wattage to plant ratio)? anybody with a green thumb in cfls mind helping a man out? if it matters, the old plant was in a bad circulated grow box, but i built a new one with a nice light rack and optimal air flow. im just afraid of plant stretching/burning. box measures 3.4' X 2.4' X 1.4, out of an old dresser drawer. the rack consists of 6 27 watt 5000k 1750L bulbs. 2 exhaust pc fans and 2 intakes at the bottom.
