My grow room is in the basement, so the temperature fluctuates between 60 to 70 degrees. But I get great yields...

72-76 degrees during light hours and 5 to 10 degrees at lights out( marijuana horticulture pg 331)

76 degrees lights on with a temperature decrease of 5 to 10 degrees when the lights go out....some strains do better at 80 degrees with as much as a 15 degree drop when lights are out...of course if you are using co2 in your indoor grow then the plants can tolerate higher temperatures.the low temps at night can influence color like blue,purple and so forth...experience will  teach ya what strains do best in certain temps.

High 70s to low 80's, you will need CO2 past 82 degrees

Sorry I was looking at something else. I keep mine from 70-80f and do not let it drop and raise no more the 15 degrees at a time.
