Should I worry about humidity ?

My RH gets up to about 65% at times and I'm at week 6 of flower. I have a 440cfm exhaust fan exhausting in the attic at full blast 24/7, 2 fans blowing air under my plants when lights are on, 1 fan blowing over the canopy towards the filter that's exhausting air, and 1 box fan blowing air from behind my tent into the small mesh screen into my tent. I've been stressing about getting a small dehumidifier but they're not cheap. 20170719_124401.jpg

Nice plant man!

I would keep your 2 fans under your plants that are only on during the light cycle turned on after lights out as well thats when you will get your highest humidity levels. Also any clusters of leaves that are heavily bunched together should be thinned out to prevent mold or at least keep an eye on them for mold if you don't like trimming. Other than that she looks great!

If RH right outside the tent is much lower, then you have airflow problem in the tent and need to increase in and out air faster.

Exhausting into the attic, this attic will probably have black mold growing on wood up there soon.

ThcGuy covered all important points well.

Just checked outside my tent in my closet and it was 72F and 58% RH. Inside the tent it was 70F and 56% RH. You think I should be good ?
