Hi
I have a grow room about 2m x 1.1m, 2m high. Four plants in there in late flower in airpots. 2x 300w led lights.
I have an 4" intake fan pulling fresh are in at the bottom, a 6" rvk exhaust fan at top supposed to be taking out warm humid air and two 7" oscillating clip on fans blowing over top of canopy.
In this hot weather I also have a portable air conditioner unit.
Problem I'm getting is constant high humidity, late 60s/70s. I have a large dehumidifier running which makes little difference. I've thinned fan leaves out to allow plenty of airflow around buds and light to penetrate further down, but still getting high humidity.
I find sometimes turning off exhaust fan actually helps to lower humidity. Sometimes it doesn't, same with intake fan.
Any thoughts? Is my exhaust fan too powerful for the space? Seems to be a lot of negative pressure, like the door to the grow room pulls itself shut when the fan is on.
