Light height for Hps and T5

  1. Well just woundering around what height T5 should be at when starting plant off? When I do switch over to my 250 watt Hps mh what height should it be at later into vegetate it?
  2. I keep my T5 about 1-2 inches from the plant. The 250watt I would keep around 8 inches or so. I keep my 150watt lights about 6 inches or so
  3. Really on T5 you can get that close with out burning it?
  4. Yeah I keep my CFLs and T5 light about an inch away from my seedlings
  5. Yea CFL's/T5's radiate very little heat. Good air circulation is strongly suggested though.
  6. Yes of course. CFLs don't get as hot as HPS or MH but they still get pretty hot. Keep a fan blowing at all times. I'm adding a stronger one soon
