humidity

If you have a smart controller you can most likely automate it, with smart controller app or from home assistance if you can. and set the automation to run the exhaust fan on an of inside this range. a humidifier will help also.

There's not much you can do.. can exhaust to same room as tent to help maintain or increase humidity -- assuming the plants produce enough to do so. Or, if humidity is rising uncontrollably you can exhaust to an area not exchanging gase with the room encompasssing the tent, but this too depends on ambient humidity beiny at or below what you want in the tent. If these things don't magically pan out in your region's climate, then you need: Dehumidifier Humidifier I grow during the winter for specifically this reason. It's probably 30-35% RH, but adding moisture is much cheaper than removing it - and a lot less heat created - evaporation will actually have a cooling effect, dehum will have a heating effect. the lights and moisture from the canopy eventually balance out around where i need it with minimal dehumidification. My late summers are very high rh, so i avoid them.

Always have an outlet point if into a lung room make sure that room gets fresh air to give to the "box". Never have it too wet or too dry. Have fans circulating inside and have control every aspect of the environment be it cave man or iron man it's the same principle. Dragging air out of an area will also drag air into it so if you only have 1 extractor then sucking out is the best and try get it away from the fresh inlet.. Good luck

It’s like a thermostat but for RH with a RH probe instead of a thermometer plugged on ultrasonic mist maker soaking in a bucket with water. Look for ULTRASONIC MIST MAKER and HYGROSTAT
