Any solution for green house to control high humidity

[AmberDawn]

I have 22000sqr of green house I'm using cooling wall to cool dawn in the summer, but is very high humidity 90% in the night and early morning

Yeah there are plenty of dehumifidiers out there, but with that space its not going to be cheap

What is the humidity outside of the green house?
