Water benders unite, humidity control

[22mucho]

I need humidity help, 3 weeks into flowering in a greenhouse and my humidity is out of pocket. I’m rocking 2 lasko super max fans 1 intake 1 exhaust and it’s still high asse. Any other suggestions?

This one is difficult to resolve in most hobby type greenhouses. The intake and exhaust fans are simply moving saturated air through the greenhouse. This air movement helps but isn't going to dry things out. Trying to use a dehumidifier in one of these greenhouses that aren't well sealed is like trying to dehumidify the whole county with a 40 pint dehumidifier. You've discovered one of the downfalls to greenhouse gardening.

I have 2 very large louvered attic fans in my greenhouse for active intake and exhaust. These fans are on a temperature controller. I also have 4 large 16" oscillating fans, one in each corner. You're realistically going to be limited to airflow for humidity control unless you invest the money to seal up the greenhouse and install something along the lines of a mini-split for temperature and humidity control.
