I'm planning to make a plant light. Searched for clorophyll info. Found it's light absorption graphic : http://www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=stryer&part=A2670&rendertype=figure&id=A2672
I have thought of something like: 4x fluorescent light tube + 50x 4500mcd red led + 50x 4500mcd blue led
The idea was that light tubes would generally illuminate the plant, and leds could be switched optionally. (Have read that red light is better for roots and flowers, blue - for leaves and energy production)
So now I'm looking for a light tubes which would fit the requirements (so that tube's light emission spectre is as close as possible to chlorophyll light absorption graphic). Not too expensive )
I'd appreciate any advice on this problem. Maybe someone is using any plant lights and would share the experience?
