Re: Effects of light on fry color development

[Wright Huntley <jwwiii at pacbell_net>]

Good question, Tony,

For shop lights that want 4' 40W T12 lamps, I like the GE "Sunsine" (aka 
Chroma 50) lamps, combined with a "daylight" to make the overall effect a 
little bluer. Note that both produce less lumens/Watt than "Cool whites." 
That is because CWs match the human eye-response very well indeed, but 
plants want more blue and red than we see.

One Cool White and a couple of P&A tubes worked pretty well, as I recall.

There is lots on lighting in the Krib <www.thekrib.co> so suggest you 
browse a bit, there.
