How do I drop my RH down when nothing works? Check Diary. Will defoliation be a good idea? Open tent door and leave it open?My 2x2 is starting to crowd. This is driving the RH to over 70%. Should I defoliate to help with crowding and RH? Or should I just leave it alone? RH in lung room is 48% Exhaust fan, high or low with a dehumidifier, doesn't work. What should I do? Defoliate? Thanks! Check diary.

Maintaining VPDI've got my photoperiod doing well in a 2x2 tent. I'm trying to regulate my VPD with what I have on hand. Currently I'm running my exhaust fan for 8 minutes every hour to get an average VPD around 1, but I'm concerned about the swings. Am I micromanaging?

I am facing a temperature problem again....My tent reaches 84.2F, which is too hot in my opinion. But my humidity is perfect. On the other hand, if I activate the ventilation, the temperature of the tent reaches 76F, which is perfect, but the humidity level drops dramatically to 35%.

Grow Tent/Room setup in the basement - dehumidifier or humidifier needed?I’m planning a small grow setup in my basement and have a room that’s holding a steady 17–18 °C (62–64 °F) with about 55–58% relative humidity. My plan is to vent the exhaust from the grow box straight outside through an existing duct. Will I need a de- or humidifier?
Thanks!Setup. Ventilation
