Lowest temp for sleeping girls during the day?

I am in a legal state with mountains. It is starting to get cold. The girls at night are in the low 80s under the lights. During the day when they sleep it is starting to get down to 65 inside. I am thinking the colder temp can help suppress spider mites. Is this to cold for sleeping plants? What is ideal sleep temp? Thanks "homies."

PS: Any idea at what outside temp will spider mites die? Will eggs go dormant or die when it gets cold outside?

..Homies? Really?

65 should be alright, though. You might even get some purpling.

22-26c without co2 26-29c with co2.
18c below plant growth slow down to a halt.
32-35 plant can handle couple hours, until it'll begin to stress and drink water to keep itself hydrated. Also THC will melt around this temperature.

18c is only 64 degrees. I'm down to 61 lights off and growth is vigorous. This kind of stuff is 100% genetics, and can't be nailed down to a specific line like that.

I run lights at night also; 80F by day (actually night, lol), down to 65F year round since I don't adjust the AC and it just works harder in the summer.

Seems fine.

It seems more important to establish stability for temps and RH, within range of course, rather than fighting for a specific number. Thats my experience, at least.
