Lighting distances

Discussion in 'First Time Marijuana Growers' started by Annual Harvest, Oct 4, 2010.

  1. Hey all, just a quick question. I just bought a new hps system and was wondering how far from the plant should I keep the light ? I only have one plant and it's a 150 w bulb
  2. If you can hold your hand on the plant top without feeling too hot, then your plant will be ok.

  3. Depends on age of the plant
    I used mine during flowering so, at first I had it 12 inches above the top to get them used to it
    Eventually I lowered it to 4 inches from the top of the buds and they are loving it!
    Just be sure not to burn your plant and it is fine
    Keep a fan on the light bulb
