Does using a black light give the shrooms the light rays they need?

I think blue is the part of the spectrum that they most enjoy. This is obviously not contained in blacklights.

black lights are lacking the green spectrum and have less red then blue. blue is the most dominant color in a black light

Blacklights produce ultraviolet light. Our eyes can see visible light in a spectrum ranging from red through orange, yellow, green, blue and violet above violet is ultraviolet light. As for are they the right lights, I would say use a normal florescent. Blacklights might or might not work why not go with something that is known to work.

I'm fairly sure black lights produce violet light, not ultra violet light. People have done many tests in the past and have found that the blue spectrum of light is what mushrooms utilize the most. The best source for this blue light is sunlight. Use it to your advantage.

It may be that it is a mixture of UV and V light. There is a reason why you are not supposed to look directly at black lights for periods of time and its certainly not because violet light can damage your eyes.

Perhaps it just produces small amounts of UV. Other wise you'd see alot more ravers with excellent tans!

A true uv light will only produce ultra violet, blacklights that you buy at a novlety shop are colored lights, they cut out colors other than purple and blues, they do produce some uv rays but not all that many. thats how my science teacher in highshool explained it anyway. take it as you will :) -zero

Thanks, you guys have been informative. I was just thinking about the idea since I saw someone using it in a picture but wasn't sure if I would really would like to try it. I will stick with the natrual out door light.

What is the difference between a blacklight and a blacklight blue lamp? The blacklight (F15T8/BL) lamp emits in the 350-400 nanometer region of the spectrum. That band is within the "UV-A" region of the spectrum that is from 315-400 nanometers. In addition to the F15T8/BL, GE Lighting makes an F4T5, and F20T12, F40/U3 (U-tube) and an F40. The "BL" type emits both visible light and UV. With a blacklight, you need to wear protection for your eyes and skin to avoid irritation. All five of the lamps listed above come in Blacklight ("BL") or Blacklight Blue ("BLB") types. The "BLB" type is made of special glass that filters out most of the visible and passes UV-A. Blacklight Blues are classified as Risk Group 1 per the ANSI/IESNA RP-27.3-96. (1997 Recommended Practice for Photobiological Safety for Lamps and Lamp Systems: General Requirements). This category is referred to as "low risk" where "the lamp does not pose any photobiological hazard due to normal behavioral limitations on exposure." In other words, under normal conditions, the lamps are safe. If you are going to be exposed for prolonged periods of time, consider wearing eye and skin protection Blacklight (BL) lamps are commonly used in "bug zappers" Blacklight Blue (BLB) lamps are often used decoratively in entertainment lighting and theatrical applications. These lamps are made with a special dark blue glass that filters most visible light. Thanks to GE Lightings web site. Just use a normal lightbulb, you are not getting any more blue light out of a blacklight blue. What you are getting is much less light from the visable spectrum and UV-A rays which can be harmful at high exposure times.
