Reply With QuoteNo. UV light is damaging to the plants and just about all life I think. They use UV light to sterilize medical equipment. Granted commercial black lights aren't as strong as the ones used for sterilizing but it's UV none the less.
Putting a Blacklight in the Growroom?
Should it be done? Just started to show preflowers. Using an Aerogarden 3 with some extra CFLs, thought about tossing a blacklight in there but dont know if its a good idea.
Info is appreciated

a reptile light is a lot better for adding uv light I never heard of using a black light for growing I don't imagine it would be very use full as they don't through very much light although its from a differen't spectrum it might help a little but probally not very noticeable
Blacklight is UVA not UVB! UVA repair's damage done to plant by UVB but not necessary.....Repti-glo UVB 26 watt 3 ea for 1000 watt's...work's best..see result's 11 more day's to harvest!!

Black lights will do nothing but waste your time and money when it comes to your grow. Save them for after your harvest.
If I recall correctly HPS emit some light in the UV spectrum anyway?
I remember researching cool tubes before I bought and one of the things I read was that they block the UV created by the HPS lights..
Don't quote me as I am pretty sure I read that on a grow forum :P
luke Yes 12% loss with glass of uv but extended spectrum lamp's such as my lumilux has enhanced blue and uvb....and 145,000 lumen's but I still use 3 27 watt uvb reptile lamp's as an aid to resin prouduction....jack1000watter as high as possible six feet 11 inches!and200 watt's uvb cfl's.jpg4th of july!! 011.jpg4th of july!! 009.jpg

Many moons ago (early 90's?), HightTimes had a small article that suggested the blacklights ended up producing larger, but fluffier buds.
While my comments here may seem to be thought out intelligent dialect, sometimes helpful, sometimes, silly, immature, offensive, or ignorant. This is just a character for online expression of personality, for MY entertainment, Not yours..
