I have 2 humidifiers running, but have to leave door open for heat reasons..so the humid air just escapes, it stays roughly from 29% - 35% and the temp is normally around 77. Is this humidity okay? Or should I close the door for a higher humidity and heat .. Heat would go to the high 80s.. And humidity would be kept at 60%. I have a bathroom exhaust fan set-up in my grow room but it does not suck enough air to keep the temps down, and now that winter is gone and snow has melted I'm sure my temps will rise more. I have 2 old dryer vents passivly taking air in from the outside, should I plug them to keep hot air from comming into my room.
