lol the black lights would only make your grow room look kwel m8 lol... soz but they dont emit nowhere near the right spectrum of light to be used for growing.

In the electromagnetic spectrum you have alsorts of waves.....(Radiowaves, microwaves, infrared,- VISIBLE LIGHT -, u.v, x- rays and gamma rays.)

in order ... although i might have missed a few out there... neway the visable light is all we can see. the RED part of visible light ironicailly nearer to infrared is used for flowering while the BLUE part is used for vegein lol the wave length of the U.V is waaay to short for plants to use m8 sorry ...

black light.. lol we need blue for veg and red for bloom.. best bet is a HPS, MH, or CFL for lighting tho CFL is not as good as the others, it will still work if your on a cheap budget.

Actually red colored bulbs from what I read have no effect. Its the light itself that needs to be in the red spectrum. Somewere I was reading like 6500k is blue? Is there a chart for this or how would one determin spectrum of a bulb on the box itself?
