Don't mean to be rude but don't the temps depend on what kind of lighting you are using? When someone is using LED, they don't heat up the leaf surface temperature as much as HID given you have more control of the spectrum. Optimal leaf surface temperature for an LED grow should be at least 9 F higher than an HID grow.You don't want a sudden drop of 20 degrees. The perfect Temp is 77 F. Anywhere between 75 - 82 & you are good with Lights on. I'm told 68 F is the lowest Temp you want to go (lights off) & 84 F is the max (lights on / without Co2). If using Co2 then 84 - 94 F are the Temps you want.
"When growing under optimized-spectrum LED plant lights, the lack of excess infrared and other unusable light causing the leaves to heat up means that ambient air temperature needs to be warmer than for the same plant grown under any light (natural or artificial) which is not optimized for plant growth."
