Reference for light requirements? Too bright?
Is there a comprehensive resource online that lists plant light requirements?
The reason I ask is because I have some plants indoors under some shop lights in a spare bedroom, but recently bought a 400 W HPS which will be much brigher.
Is there some point where lights are too bright? even when temperatures stay around 75 degrees?
So I guess I have too questions:
(1) where can I find a comprehensive reference that describes plant light requirements in terms of lumens / foot candles and
(2) Is there such a thing as too much light "burning" or otherwise damaging plants at regular indoor temperatures?
I'm mostly propagating plants under the lights, the plants I have inside now are hibiscus, hydrangea, and wisteria cuttings, but will start some acer seeds soon.
