passive intake and humidity

[S13Hitman]

Having trouble raising my RH because my exhaust runs 24/7 since I have a passive intake setup. I've tried multiple humidifiers and wet towels and still can't reach the right humidity I need.

Is there any tips or suggestions you guys have without changing my ventilation setup?

Thank you

Ultrasonic foggers seem to be the go to for an end-all solution. Haven't used them personally but there's loads of information here if you search around.

What is your current RH& temp, and your desired RH? How much are you trying to raise it?

evap ac, freestanding or through the wall, hook up water hose. 165 watts. 550bucks oz. get your humidity up quick.

The higher the heat, the lower the RH...

What about the environment that the tent is in? Is there a way you can simply raise the room humidity with a humidifier? Since the air is being pulled in through there, that would seem to make sense? Easier than trying to hold atmosphere in a vacuum.

Swamp cooler! Gut it and use as passive intake. Works like a lucky charm!

Why did you say to gut it? Are you talking about using a store bought one, or a DIY swamp cooler aka a fan over a bucket of water?

ya those home depot or regular home humidifiers dont work for shit. I bought 3 in total, for 150sft space or so, with a constant active exhaust system and they didnt help at all. Ive been able to keep my humidity up in the active exhaust room now, by keep the inline on a speedster, 8" fan running at the highest low setting barely pulling out air. also making sure you have enough foliage or plant life in the area, the more condensed the room is with foliage and medium the higher the humidity will be obviously, so try to keep the room full . maybe grow some tomatoes, aloe, or other random plants nearby if u dont want to grow too many canna plants. i also let my runoff just hang out and evap off the floor doesnt take too long, and with everyday watering it stays pretty consistent. room has been a constant 60-70% for the last few months. will see once summer gets here tho.

For passive rooms i usually dont have much problem keeping the humidity up. if thats ur only way of cooling the room, keep her on a controller and if its cool enough outside and not too many btus in the room it shouldnt have to run 24/7. but if its not cool enough outside its not worth trying save $ on running no ac
