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
No. 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.
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!! Barney's Farm LSD..jack!View attachment 2241367View attachment 2241373View attachment 2241374
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....jack
Certainly would like to read that...active spectrum for plant is 400nm to 700nm....black light's are far red..800nm-900nm.....Par photosynthetically active radiation is the only light used in plant growth...so??????290-300nm for resin production UVB...UVA 320-400nm phototropism...(following sun!)...jack......
