Grow room temp and humidity

Hi Everyone,

I wanted to know if anyone had any advice on how I can get my humidity up in my grow tent. I woke up this morning and my temp was 68F and the humidity was 20%. I live in Southern California and it was dry as hell yesterday. I had a humidifier running in the tent all night. I think the in line fan I have is so powerful it just sucks out all the fog before it can do anything. It's almost like its too powerful cause the temp doesnt get high enough either unless I turn the fan off. I tried a wet towel in the tent and it didn't work that well. Any other advice?

Whats your ventilation setup like?

I have a sun hut 2x4 tent. It has built in vents on the side and in the back. The inline fan is pulling out air directly from the reflector. And there is an oscillating regular fan on the floor of the tent just to keep the air moving.
