High humidity in grow tent

I dont know what to do, even with a 430 cfm inline fan, my tent is still showing 80% humidity in flower.

do you have a extractor fan ,outlet ,

430 cfm inline the sucks the air out, and i leave the doors open halfway, still getting 80% and after i water im getting like 86% and if i zip it up who knows maybe even higher, how do people use tents without getting mold?

What is your set up? Lighting, temperatures, etc.?

Are you growing in soil\soil-less? How often do you water and when?

If you spray anything on your plants limit it to just before lights on or shortly after. I would recommend you go out and buy some DampRid. They have a hanging product designed for closets and the regular crystals in the slitted container... both work.

You need a dehumidifier.

Did you solve the problem mate? If so, how?

yes dehumidifier ,will get that RH down mate ,
