Humidity Problem

I put my girls in to flower photo-period by two days ago. But I think that My humidity still to High about 70%. what the best way to put it down? any suggestions? thanks

I have a oscillating fan inside i should put one more?

Air always helps, but try hanging some dry towels up, and put the fan blowing on some salt.

nice I going to try it. But how do I put the salt?

put the salt in a 5 gal bucket and pass air over the top

Nice!!! I m going to try it!
