I just got my room all set up lights, fans etc.. i was testing my room temp/humidity. My temp after 2 hrs was 76/77 humidity 30/35 are these good. Im pretty sure that these are all good?
What is your setup? More detail. How many lights,wattage, volume of room, soil/hydro? When you setup a room and run tests, you have no plants. When the grow starts, humidity will be low, as the plants get bigger, they aspire, humidity becomes an issue. Humidity can be controlled a couple of ways. Exhaust, dehumidifier, A/C, Chiller. Tell us about your setup. Have any pics?
