How close to keep CFL's to plant??

Discussion in 'Indoor Marijuana Growing' started by cody8892000, Feb 8, 2008.

  1. how close exactly should 2x26Watt 6500k CFL's be to the plant.... i read some thing that said to keep it within an inch or two and i tried that......and it burnt my plant before i could:( ...its in intensive care right now though haha but really about how close should i keep these lights
  2. No more than 5 inches away, try 3-4. And get a fan on them to blow the heat away
  3. will do....thanks alot
  4. word. and with good ventilation you can go even a bit closer.
  5. 2-3 inches even without good ventilation, especially with only 23w cfls, just make sure the temp isn't above 90.
  6. 1-2 inches is best. If a CFL is 4 inches away instead of 1 inch away it is delivering only one-sixteenth the amount of light. If your plants got burned then they had to be touching the bulb, and that indeed is too close.
  7. Hey toasty biz, good to seeya on the posts again. This man was just one of my mentors, listen to him. HE KNOWS HIS SHIT!

    2 inches i'd say is best.
