Humidity? too High! HELP

So when my room is in its dark period my hygrometer reads 68 F and 65 percent humidity.....i am ghetto'n it with no exhaust but i do have an air in...my question is im in week 4 or flower and i am starting to lose sleep at night over mold and all that...my room is 8X8 and i have 2 fans goin...one on circulation and one just blowing upward....meanwhile i have a fan mounted over a vent linked to the outside drawing in fresh air...What can i do to avoid powder milder/ other molds?

You could always buy a dehumidifier. Not exactly the cheapest thing, but if you plan on growing on a regular basis, it'd be worth it in the long run. You can probably find a cheap one for like $50 or so.

Dude you need an exhaust before an intake. Get a dehumidifier and set up an exhaust, just use passive intake.

okay...so passive intake meaning door craked? and vent thru my vent that goes to outside?


or should i suck fresh air in thru my outside access and vent thru my open door (cracked)? thanks


ALSO i have access to an AC unit...could i lower nite temp to get rid of humidity issue? everything else is a plus the temp rite now is 71 and the lights are off when they flip on its 78-79.5 thanks guys!

that's a livable range, if you've got good air movement no molds will form. A used dehumififier would be a good investment. A small 15 liter one is adequate for just a grow room.
