well you could go smaller say 4-5 each tent or room and have one on 12/12 then take the other 12 hours and grow another then somethings always warming something lol! Just a thought!

well i was thinkin in the night when its colder so the light warms the room up and give them the rest of the day to recover but even then the days are gettin cold anyway cause its winter so what would be the best, on at 12 at night and off 12 midday?

i do 7p-7a off. as long as you exclude any light during dark cycle, any schedule will work. run a small heater during dark if RH swings.

Check with your Power company, here, PG&E charges more for elec during the hours of 2pm-9pm. I like to run 9pm-9am

I also run 9pm tp 9am. So the cooler hours the lights are on for heat as well as light. When the temp goes under 68 a heater comes on when the lights are off. All that's really needed is 12 on and 12 off.

I do it as close to sun down as I can get so dont have to worry about light leaks and hermie situation. Just set some to 7-7 which is like fifteen minutes before and and after the real sun up and down here

Whenever. I programmed my timer for 9 and 9...I didn't transition the 24/0 to 12/12 but shit, I had females in 2 days. Might have stressed one a little bit because she's hesitant about budding even though I can see her preflowers but the other is growing hairs on all branches.

Don't know about there, but it's a bit less expensive to run the lights at night.
