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

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

Many moons ago (early 90's?), HightTimes had a small article that suggested the blacklights ended up producing larger, but fluffier buds.

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......
