when do I change DIF ?

[littlemountain]

I try and keep the temps as close to 78 degrees, (at the canopy) as I can. Lights on - lights off. I try not to go below 70 degrees.

far-out an answer :thumbsup:

I am 5 weeks into 12/12 my my high is 81 degrees and that is minutes after lights come on- a spike in transition of heater going off and lights building heat- rest of day 77 -78 high - night temps are 66-67 degrees when should I raise my DIF and what is the night low I should strive for ?
