Nerds. Lol.
The pink is the new rage in hydroponics huge European food production facilities are using them now. I kinda totally want one but I think it would mess with my OCD when I stare at my fuge critters.
Check out the one from kessel. Omg.
Reef lights actually should work worse than cheap lights as cheaper lights contain more of the R Y and O spectrum plants usually get from the sun. I.e. Full spectrum. Reef lights are not truly a full spectrum though some advertise they are.
I use a 5600 (daylight) and a 3200 CFL from the dollar store. Actually the same color combo my wife's orchid society recommends for completion flowers. That or one soft white and one cool white fluorescent tubes.
Intensity does count as intensity is a component of par. and if your growth is slow in the fuge it's not a bad idea to up the intensity. Or add spectrum.
I suppose I could meter how much light is in my fuge one day. But that may cross that fine line of crazy.
