can Incandescent lights interupt flowering?

ok so its my belief that you cant grow squat under good old fashioned incandescent lights.

if you open your grow tent in flowering phase during the 12 hours "night" with an incandescent light on, is that going to "wake up" the "sleeping" plant, AKA ruin things?

absolutely possible. Incandescent light may not be efficient enough to properly grow herb, but it sure can make your chick grow balls.

bugger ........

depending on how close and how big the incandecent is ...something like 5-10% of incandecent bulbs give off the usable spectrum.....i would deffenetly not do it. i heard green LED's are good tho

2 or 3 minutes under incandescents won't do anything.

2 or 3 minutes everyday just might.
