9 hours light, 12 hours dark.

after a few days they won't sleep even if lights are off trust me

what do u mean they wont sleep if the lights are off.... no light... no photosythesis...meaning they are in a dark period.

[Weedhound]

Sleep?!

[mafia819]

i was quoting something kindprincess says about chickens... ;p

[Tomthehippie]

Keeping thermal heat images down at night when eventually time adjusts to the light being on at night would be a bitch.

Oh. K

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

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

gftf, i see no probs with your idea. if you're worried about a heat sig, then line your room with board insulation. then you wont have to worry.

to give you an idea, we are running over 2000w, no heat probs, inside temps are in the 70's, and the rooms are insulated.

[BOYZNUS]

no you tards.. you simulate more days in a shorter span of actual time... there are actually already like 10 threads about it in the advanced technique section. well at least like 3.

THEN IT LOOKS LIKE YOUR QUESTION HAS BEEN ANSWERED.
