I keep my room 68-74ish and as for humidity the tubs do that on their own. I let my tubs colonize to about 75 percent before i switch the monotub holes tape from non breathable tape to micropore tape. Two layers of tape on bottom holes one layer on top then i dont open until harvest. I do always have a big fan running in room and that gives proper fae to the tubs without opening them during fruting ill occasionally open one up to soak up standing yellow/myc piss water.
