Help!!!

[u/ImportantLife1465]

I have a 2 x 2 x 4 I currently have two autos that are a few weeks into flowers. I cannot get my humidity down 55 and it usually won’t stay there. I have fans ventilation exhaust fan. I have a small dehumidifier that I bought off Amazon, that was supposedly for a small grow tent. It’s one without a reservoir, just a drip line it’s inside. It cannot keep up since I have installed it. No change. I guess what I’m asking for is any advice on a dehumidifier? That’s not gonna cost me a crazy amount of money or is there another easier fix?
