Quick answer-NO !
Long answer- they do not emit light of the properwave length to encourage photosynthesis.

They DO work just fine.

If you spread Visine on your cheeks, it will make bright yellow streaks! :blsmoke:

I will give you a quick lesson on blacklights. Blacklights are not good for growing by itself, but they do accentuate the other lights and the potency of the plant. Blacklights should be used in cogruance with other "grow lights".

Blacklights should be used in the flowering stage, as they emit the UVA and UVB wavelength, which is what the natural sun outdoors gives off. Don't we want our growroom to be as close to the normal sun as possible..? Use caution though, UV light can damage the eyes and skin, especially if you have a powerful UV light, with prolonged exposure. I suggest using sunglasses when under these types of lights.

Blacklights increase the potency of the plant, by forcing increased trichome production(which in turn makes more THC, CBD, and CBC's in the plant). This is good for low trichome strains such as Durban Poison, or Afghani(what i'm currently growing right now). Actually any strain at all..

The way it forces more trichomes to appear, is in response to this harmful UV light emited from the blacklight. We get dark when were in the sun(UV light causes us to tan, a way to block out this powerful UV light) but plants protect itself by making trichomes to block out this light.

I have just recently installed one in my growroom (40W fluorescent blacklight), and I am waiting to see (i'm in the last 1-2 weeks of flowering) how the trichome production will be affected.

Well I hope this enlightens you to as how beneficial blacklights can be to any grower, commercial or just even personal use.

I recommmend spending the few extra bucks to try this out, and see how the potency of your finished product will be affected.

Take care all, and keep smoking.

Off-topic, how'd you pick your name? Wasn't "stealing the name of jah" by any chance?

Blacklight doesnt emit the right spectrum of uvb...you need btween 279 and 320 nm(nanometers) light...which is something you can get from a reptile bulb at a pet store.YouTube - THC, UVB and Me You still need regular grow lights, the reptile bulb is a supplement.

There are different types of "blacklights that you can purchase. some are not even black at all, but clear.. A regular blacklight emits mostly UVA light, but also some UVB light. The best light for UVB would be as Stoney mcfried said, a reptile light.

UV-A380nm - 315nm Long Wave (black lights, concerts, entertainment)UV-B314nm - 280nm Medium Wave (forensic applications)UV-C279nm - 200nm Short Wave (germicidal, sterilization)

make sure to get a fluorescent black light, the kind with a fluorescence tube, and not an incandescent black light, which is a regular light bulb with a special coating. Incandescent bulbs aren't fluorescent and therefore don't work.

I heard that if you leave them on during flowering for just about 5 minutes a day and increase the time there on every other day till harvest that the wavelenght of light tells the plant to protect itself from the harmfull lightwaves thus creating alot more resin and thc clusters, seen it before and it is the most trippy weed ive ever seen, looked like it had clear round orb like things all over it!!!!!
