Need advice getting humidity down.

Hello fellow RIU members. First time grower here about 8 weeks into my grow 3rd week transition. Time of the year has come in the Pacific northwest for humidity to sky rocket.

Humidity in the tent had been holding steady between 65-75% RH running 3 basic computer fans for my excaust and a passive Intake(still getting suction in the tent)
So far I've been looking into 2 solutions:
Dehumidifier. Not sure if I can get away with doing just my tent or if I have to do my whole room as well and what size dehumidifier I would have to get. My tents 60 cubic feet and my bedrooms around 1300 cubic feet.
Intake filter. would it be a more viable option to run a intake filter and scrub the air coming in to prevent mold/mildew/bugs rather then to try and bring my humidity down? Trying to keep the cost I'd this project below $100 if possible.

Thanks again to everyone that has helped out. One forum I know I can count on.

Not sure what your temperature is but my grow shed was getting cold and I stuck a small heater in their and my humidity went down and temp went up, it ended up being perfect! You can even get like super small heaters.

Currently running around 70-75 degrees in the tent right now. I could try a small space heater and see if that could drop my humidity. Or possibly cranking the power on my lights up a bit. Need to bring my humidity down atleast 20% though.

I've got a humidifier and space to put it in my tent, but I don't bother because I have a pretty good exhaust flow - I figure it does about the same outside in my bedroom.

If you’re using a dehumidifier keep it in the room first. Then move to the tent if humidity is still too high.

Humidity is relative. Meaning 65% at 70f would be around 50-55 at 80f.

Heat is not the best remedy. Although you could keep ur temps between 75-80 and see how your plants/humidity respond. Either dehumidifier or move house :)

Btw great humidity for vegging :)

I bought a small dehumidifier and have it set on Auto in my 4 x 4 tent. Works really well and solved my problem. Cost more than $100 but less than $200

You can always watch CL and fb sales sites for them. I recently picked up a dehumidifier for $20. Works great.
