9 hours light, 12 hours dark.

unless you expect that; and grow in a reverse scedule...

the 9/12 cycle is not fixed to a schedule of "earth days" and therefore the hours of the light period will be staggered, and fall during dark hours sometimes and during light hours at other times. is there really any risk of this? i grow somewhere that this sig would be obvious (like one board between the outside and 1400 watts of HIDs) i live in an urban area, near a buncha street lights and such. sorry to jack the thread, but wait its my thgreaqd in the first place
