Hi all been looking at dehumidifiers and before i go spend $500 I'm curious if a 10-20 litre per day dehumidifier can counter a swampy cooler?
The swampy is on in the house a lot I have a 5x5 tent in a room, the room is generally around 70 - 80%rh and the tent is 70- 90% rh I'm wondering if I could bring this down quite a lot been looking at a couple 20l/per day but they say that's at 32° and at 26° it's more like 10l/ per day.

Or even just in general a tent where the air intake is 75%r h, I'm thinking even with a dehumidifier i n the tent the exhaust is just going to suck all the dry air out

You're going to need to isolate the room from that swamp cooler. The dehumidifier probably can't keep up with that constant input of humidity, along with what your plants will produce. In this case you need to fix the source of the humidity.

The problem you have is the air exchange. There is no way the dehu can keep up if it's fighting the swamp cooler. As the tent exhausts air outside it will be pulling humidified air into the room. The room the tent is located in (I will call it a lung room) needs to be cut off from the swamp cooler, install a portable AC in there instead. Then recirculate the air from the tent from and back to the lung room instead of outside which would pull a negative pressure on the lung room thus sucking in humidified air unless you provided an intake from another source with acceptable #'s. Once isolated from the swamp cooler you can control the temperature and humidity of the lung room and thus the tent.

Just as I thought lol I think I'm in the land of fucked.
I've closed the vents from the swampy but some air still gets through and as the window is open in the room for my exhaust I find some also come under the door from the rest of the house. Ok could close the window which might help then I guess I would just have to vent the room daily tho.
Something else I was reading is that I can try build a box around the dehumidifier have a hole near it's intake then make another hole near where the dehumidfied air comes out then put some ducting there and have my tent intake draw from there but I'm unsure how well that would work

So your houses humidity is 70 or 80%?!?!? A little dehumidifier isn’t going to do anything.

Yep it sure is but that's what happens with a house that has a swampy ducted to every room I hate it can't wait to move out soon but in the meantime I'm almost 2 weeks into flower and need to try get through without mould, then not do anything one till I get my own house in 6 months or so. I have 3 oscillating fans in the tent but I fear it's not going to be enough. And these plants where monster cropped just how the clones where when I got them so there bushy as fuck.

So your unable to control the humidity via the humidistat? I mean that high of humidity can and will damage the house. I have whole house humidifiers on my house and on all of my grow rooms along with anden 225’s per room to keep the humidity perfect no matter what. unfortunately even my biggest dehu would be able to keep up if the humidity is staying constantly that high. My biggest is a quest 506 for reference.

A swamp cooler works by misting air and circulating with a fan
It is the mist the makes it feel cooler
No humidifier or stat will change that

It's a southern thing cause you can't use one in cooler climates

So where I'm from people thought it would be a good idea to make big swamp coolers with powerful fans then put the unit on the roof and duct it to all the rooms in the houses, as a cheap a.c. option they work ok but not great and humidity becomes rather high. So no if it's on there's no control over humidity.
So I'm looking at dehumidifiers but don't think even a great one could keep up with the tents extraction but Mabey I'm wrong.
Other option I was thinking is put the dehumidifier in a box and draw the air into the tent from that box.
