Whats more important?

[Fuzzy1981]

i was just thinking about my next grow. in the winter time i can either keep the humidity high, or the airflow going on it's lowest setting during the day. and then kick on for fifteen minutes every two hours after lights out. the r.h. of my basement in winter is 30 percent. so whats more important? humidity or airflow?

airflow by far... I don't even really worry about my RH until it gets way low or way high and at 30% you have nothing to worry about. Yes, it could be higher during veg to help out growth a little, but having good airflow is so much more important and can keep away several problems such as molds and fungi. Plants need to breathe and the more airflow the better.
