I was looking round for plant lamps. Ended up buying a Phillips plant
and aquarium T8 tube.
Been reading, but no really good info. I'm not growing a big crop,
just seeds. I'm
just trying to keep them warm right now. Got heat and halogen lamps.
There are various CFL's and
I have a few dozen myself, of different colors. I know you need UV of
some sort.
In the past I have used black lights, not for plants. there are at
least two types of Black Lights or BL.
One type is filtered, blue tube. The other looks like a regular
florescent and when its on looks dim unless
it fluoresces something. I know these have a good UV output since when
I used them, would bleach out colors
pretty good on objects close by, but is not the hazardous germicidal
types. The only thing I know will work is
metal halide arc. Maybe some automobile arc lamps ??

Anybody know more ??
