Just depends on ur location and house/room ambient temps, I have 11 tanks in one room three of them with overhead lamps and the rest with uths BUT I’m in Florida and we keep the house at 76 through out the day and my vent to the room is closed so it warms up to 79-82 through out the day. Che will kill ur humidity so I suppose if you can counter act it then that’s good to go.
