Can you open up the tent? Air circulation helps with humidity—- seems like that’s the problem…

If running a vent fan it is almost useless to also dehumidify. The vent fan can draw in humid air faster than a dehumidifier can remove the moisture. Your dehumidifier will run continuously and have minimal impact on the humidity. If you do not run the extractor fan then a dehumidifier will work. The problem is then the heat generated by the dehumidifier will warm the tent. Also, inexpensive Peltier style dehumidifiers are almost useless. They do work... sort of. They work so so when the humidity is really high but most do very little below 60% RH and really struggle to ever obtain 50%. Compressor type dehumidifiers are much more energy efficient and they are much more powerful and able to obtain much lower humidity. You may still have a problem with heat buildup in the tent. It all depends on your conditions since a compressor type machine will not have to run continuously like a Peltier machine. A really good solution is to hack a window air conditioner. Modify it so the conditioned air can be blown through a hose and you can both dehumidify and cool your tent.
