short answer: incandescents have alot of energy in the 700-800nm range. MJ needs 730nm light to convert parts of the plant(phytochromes) back to a 660nm acceptable state. its a cycle. a better plan would be to use the incan's all day, then run incandescent black light party bulbs for 20-30 min after lights out. these bulbs have only 700nm and up and a small bump at 400nm w/ the rest blocked out. we did some testing on this and saw some better results.

long answer: theres a raging debate going on in the perfect LED thread with talks of all red "martian" nights and all sorts of other ideas. many have great merit and require much testing.

lol guess the long and short are backwards....:upsidedow
