it is what it is. If you're like me trying to survive what do you do. Heater is blasting and I have space heater at the intake and barley over 60. Under 50 I'll worry. Last power outage I got a little bud rot on one ripe plant..

Lower temps overnight, depends on stage of growth.
for youngins I don’t like it below 65.
for flowers. It can drop into mid 50’s. That’s what brings out the colours.

They will grow, but slower than optimal.
get a heat mat. Or plug in a space heater.
more about keeping soil temps warm.

Just make sure it doesnt fluctuate 10 degrees lower than what it gets when lights are on.

The tough answer would be to insulate your basement. Really hard to control tent temperatures if lung room temps fluctuate
control the lung, control the tent.

Dial the exhaust back if you can. Keep the warm air in.

Yes. Dont let it drop that cold. If you were locked in the room 75 degrees all day and when you laid down for bed the temp got below 65 you wouldnt sleep you wouldnt rest youd go into shock.
