Open Exchange, will Dehumid Even Work? (80%+ humidity)

usually just keep a healthy open exchange in my room, but humidity this year is absolutely off-the-charts ridiculous. Recently we've been suffering humidity consistently over 80% and often enough over 90%, and I'm a week from harvest. Humidity in the room is only so much better. I have tried running the air conditioner, that helps a bit and would help substantially but I don't want the temperature going way too low so I can only use it so much. I've also tried using Damp Rid, which if that made any difference it was fairly unnoticeable, I wasn't impressed. [[FOR SOME REASON MY COMP ISNT LETTING ME END THE PARAGRAPH]] I have a carbon filter held over a 1000W cooltube being pulled out only a few feet away by a 424 CFM inline fan. Will a dehumidifier even help at this point, or am I just pulling through too damn much fresh air for any of my dehumidification efforts to work?

buddy why not try one of those littleones they use for the bathrooms .......u could get 2 of them one for inside the then tent one outside for the room and u would be reducing it in both places .............they hold about half gallon and then auto shut off ........u could use for watering if u want

there is one choice too but u might now like it ................a propain burner in the room and well cook the room reduces the water with a open flame for a bit then blug in the dehumitifers

or u could get a ac unit and tweak it so it is on cool/ac when the temp is right it just bolows but to hot it colls and dehumity......this is the method i use the highest my tent got was 65 % humity but that was with 4 days of rain norrmaly holds about 48 53 area
