Using GREEN LIGHT while 12/12 IS ON! HELP

  1. Ive heard that you can use a green light and also heard a red light ....that you can use them in the 12/12 cycle so you can look at the plants in the dark and foiler spray easier without tripping over stuff...since its easier to do it in the dark....anyone know if you can use a green light while your budding in the darkness? and it will not affect it ? or what im scared to try it. ?any advice would be greatly appreciated.
  2. I think they mean green spectrum, red spectrum, not actual green lightbulbs. Im not too sure about that though
  3. well would green spectrem mean a lightbulb green i dont know im hopeing you can use a green lightbulb to look at the plants in the dark that would be cool
  4. Yes it's true about the green spectrum. How to do this I am unsure. I originally thought green light bulb as well until I realized that yes, a WHITE light bulb produces all colors of the spectrum, so obviously a green light bulb isn't just giving out green light. If you find out how to do this, let us know.

    On a side note, don't foliar spray at night (or lights off). Not necessarily going to kill them or anything, but it's best to do it when the plants are "awake" so they can take in nutrients and everything.
  5. but they make those green party lights that are green and verry dark when you have one on....what about one of doesnt put off like white light...just green

  6. Time for Physics 101:

    The green paint on the bulb will absorb all colors that are not green, and only allow the green part of the spectrum to show. So a green light bulb (the kind you buy at the store) will only give off light on the gree part of the spectrum. It's simple physics on how light works: when you see a color, what's happening is that all the other colors are not being absorbed. That's why you can use the green light, because the plant itself reflects all green light, which is why the plant looks green.
  7. Yes. Try taking a regular flashlight and putting some green cellophane paper over it to get green light. This will be fine for the plants at night and they will not "see" the light.
