whats a good dehumidifier for a 2x4 grow tent

What the rh of the lung room mate if that high aswell then I would run one in the lung room if not can always get your intake fan and extraction fan turned up to move more air into the tent then if not you can buy small dehumidifiers that should fit in the tent aswell 

@coops98 what’s your ventilation system like. What’s your control trigger, humidity or temp, or both? I use AC Infinity controllers that allow me to set both humidity and temperature thresholds. If you don’t have anything to monitor humidity, it’s going to be a good trick to keep all the balls in the air at the same time. You almost always have a humidity burst to deal with at lights off. When I started growing I pretty much ignored humidity. That cost me a few times.

@jdog I don't actually know what my humidity or temp is of my lung room mate i don't have anything to read it. I normally just stick my intake fan out near my window when the lights are on. When the lights are off depending if it's been raining outside or not I put my intake ducting into my room. I have just oderderd a dehumidifier of amazon that should come tommorow got a right bargain hopefully it does the job. Last thing I want is my girls to suffer.

@coops98 look at getting your self a hydrometer for your tent and lung room can get ones that do two zones at once so you can monitor everything the ac infinity ones are mint can view it off your phone and check when its at the highest and lowest aswell as temp

I really like this one from Amazon, it lasted me at least 3 years and is still going. I just had to replace one AA Battery when it died on me. I recently bought 2 more, 1 to put inside the tent, 2 in the grow room and 3 outside the grow room to compare them the temperatures and humidity for different spaces:

I also have 3 of these that can probe the soil/grow medium (I had 3 before but they are cheap and didn't last that long as you can't replace the battery):

I have bought a humidifier before but I don't really need it, putting a bowl of wate in the tent and letting it evaporate from the tent heat works just as well and is free.

EDIT: Doh, you meant a dehumidifier, I have never needed one where I live, as long as your fans are blowing it wont really be a problem I don't think.

@monkeydo sorry monkey I did reply to you but realised I had attached a photo with my postcode 😵 in it and came on and deleted it quick and haven't had a the chance to reply. So basically I was putting my intake fan tubeing outside during the day and at night bringing it back in depending on the weather. After your comment about humidity causing you problems I went and did some research dident even realise they have little mouths they breath from on the leaves stomata's I think there called. they can close up if there is to high humidity or to dry pretty cool that. I got myself a dehumidifier now which has helped alot I'm still struggling to get it below 65 humidity but I am hoping once the 2 weeks of flower is done I can get in defoliate hopefully that will help bring it down😎 .
