thx for the replie,
68? not 78.
either way your saying it should be the same lights on or off?
thank u

My plants like it better around 72 to 74 at the canopy. During flowering I like to drop my night temperatures to the low 60s, seems to help with the "fall colors" on the plants.

74* day (lights on).
64* night (lights of).
No extraction or oscillating are fans are required during the dark period.

No problem. You can have the temps up to around 80-85* during the daytime(lights on). Then just make sure you have a 10* drop in temperature at night(lights off). I always run at 74-75*day and 64-65* at night

(good luck).

I was just wondering why it should be 10 degrees colder at night? Or any temp difference at all? The only reason I could think of is so you could try to bring out the purples?
