How close can my 24 watt t5 get to the seedlings?

  1. oh and the light is being partially diffused by the clear plastic lid on my propagator.
  2. 3-6 inches.

    You can put t5's as close as you want as long as heat isn't an issue. It'll keep em from stretching.

  3. thanks for the reply bud, heat definitely isn't an issue at the moment. Might even put them a bit closer ;)
  4. with all lights, one of the best (if not the best) ways to test for light heat is by the back of the hand test. hold the back of your hand up by your light. the distance you're wanting to place the light from your plants. if the heat is too much for the back of your hand, it's too much for your plants...
