Above 60, to cold you will affect the rootzone temps. Buds can deal with it, the roots get cold thats when you worry.

I veg my plants at 80 egrees with around 65% humidiity. These temps are good untill the fourth week of flower. Then I bring the temps down to 75 with 50% humidity. These are my lights on temps. I try to have no more than a 5 degree variance at lights out. Two weeks before harvest I try to bring it down to 70 degrees and 45% humidity.

Thats awesome, simulating the transition of fall. i bet you get great results from that. My setup dosent allow for quite that precision but i try and do the same thing, though i can never seem to bring it down to 45%. I end up somewhere inbetween 50 and 55 by the end.

I like no higher then 78 deg no lower then 65.

You just dont want it colder than 68. You dont want it warmer than 82.

70 to 80 is perfect. Lights on 80 lights off 70.

Once you get to fading the last week. You can get down to 65 with the lights turned down.
