Hey peeps need a recommendation on a dehumidifier for a 2x2 tent. It's wrecking my head trying to find one. My humidity isn't good atm.

Stay away from tiny dehumidifiers , they do nothing.
Dehumidify the room the tent is in so the air going in is lower RH.
Whats your set up? Where does your extraction go to and where does new air come from?
What RH are you at?

Rhino Hobby Carbon Filter Kit, Centri Flo Fan. Intake is just the basic eco fan. my extraction just goes straight out the window. Intake is pulling air from the room. Humidity 67-71

What do you mean by letting it build up? As in fans shouldn't be on 24/7?

There is little point controlling humidity. We just use extraction so when the plants transpire that moisture is removed. Yours is going out the window but if you exhausted into the room and sealed everywhere that moisture cant escape and will build.
Some myth that high humidity is bad, its not really and moisture cant just drop out of the air and mold buds if you dont give it an exscuse to.
Your humidity is linked to your weather, if its 50% outside and you have a window ooen its 50% indoors too. Fuck one day it could be 80% a.d raining or one day hot sunny and 25%. Point is no one gives two tugs of a lambs tail, the principle of air flow and not letting it build is all you need not sealed rooms with hardcore climate control that will set you back a ton of cash.
Keep it simple, theres too much wrong info you end up thinking you need specialized equipment not a tent light and fan as is normally sold for indoor growing.

Interesting, so if I'm thinking right now your saying theirs no need for my intake to be on? Just extract the air from the tent into my room. And seal up the room so air can't escape.

Moisture drops out of the air all the time. Called dew. It forms at night after the temps drop. Don't base everything on your provincial experiences, some places have 90%rh for weeks. Of course they need air treatment, it's not the Lakes District.
Just use passive vents to take air from room into tent, blow it out the window since it is hotter and higher in humidity. If you want to treat the intake air, treat the room you draw from. Use the booster fan to get cool air to the room/ intake duct from a cooler area if needed

The inside of my house dosent reach dew point and neither does my tent, if either did i would have moldy buds as well as a moldy house and shit like life would be pretty hard.

Do nothing you already got it set up right. Advice was to stop thinking about humidity.

Kwl, I feel more at ease now, I've just put in a ram 6inch clip on fan.
I have plants in my wide open basement and noticed dew on the walls about three week ago. Condensation formed at two of the wall/floor corners of the room.
I'm running my whole house Danby down there now. Set at 65%. The machine turns on at 70% and dehumidifies to 60% then turns off to 70%..... but basically it runs most of the time and instead of watering my crop once a week, it's every few days now.

Its fricken 60-80% humidity all week with this rain in the Uk where i am. Dew point is 7c atm according to accuview,no part of my house or grow is that cold. Its 12c outside i can just about feel the moisture in the air. Possibly this morning dew formed in between the rain when temps might have fallen lower outside on cold surfaces.
Now my grow is between 19c and above, i will never reach the point water leaves the air and could cause mold.
If i shut my extraction off it will reach air saturation quite quickly in a small tent with many plants probably causing mold or water to form on tent walls and roof. 80-100% is a short jump here.
A six inch fan is great but point it away from the plants, were not looking to make it windy at plant level but circulate the bulk of the air so the plants experience air movement.
Low humidity is never a problem, you could even add humidity say bring it from 20% to 50% but there is no need and you wont see any difference. A healthy happy fast growing plant will enjoy a warm dry environment as much as a warm higher humidity one, humidity itself is not a very strong force whatsoever, its not like strong wind which will pull water from your leaves fast or strong light that can cause a lot of transpiration. More a minor variable that if everything else is in check will take care of itself.
Who wants to use exspensive troublesome climate control if you dont have to, say it was really hot an ac would be great but its a killer on the electricity so you take a hit one way or another. We have pretty good conditions and most of my grow switches on for the night times all year as this seema the easiest and best solutions to hot sumners and cold winters in your indoor climate.

It's not facing my plants. UK weather is poor lol. I made a mistake last week when I shut down the intake and extraction for the night don't ask why!! And ye it looked like it had been raining in my tent... bad move! Any way.. My humidity is a steady 60 now running 24/7 I was faffing about way too much with fans on then off ECT. On my humidity and temp reader shows temps dropped to 16c in the tent last night. Also keeping my tubular heater on over night now keeping temps at 22c.
