Black light

  1. Will putting a black light over my little plants to emulate a night time setting help? A friend of mine told me it would, and could also make my nugs a purple-blue tint. Does anyone know if this is true or not? I've never heard of anyone doing this so some confirmation would be good before I take his advice, thanks!
  2. If your lookin to grow purple plants leave them out in the cold a couple times. I dont know how well using a blacklight would work for that.
  3. yeah I dont want to kill them accidentally though, it gets cold up here!
  4. if you only do it a couple times theyll be fine. it takes more than 1 night of cold to kill an mj plant
  5. thanks man i appreciate it!
  6. Yeah man, The whole blacklights giving bluish or purple hues made me have to go get the wealth of info on here.

    Good luck!
  7. Blacklights have no place in a grow room. OP your friend is an idiot.
