  1. what does it do to ur plants and for what do i use it i already have a halo gen light
  2. dude infest in some flurescents and an hps loose the halogen I dont no about ultra violet but my guess is its not gonna be the right spectrum
  3. get rid of the halogen....it will kill your plant.....use fluros or HID lighting.....read the growguide below my sig....it will help yoiu......Peace out.....Sid
  4. "Supposedly" some sort of UV rays are beneficial for mj but "apparently" blacklights don't emit enough of it to make any difference.
