According to my research, I found that the 2 best dehumidifiers are the best in the market right now for different-different purposes. 1. If you want a dehumidifier with some advanced features then the Vermi dehumidifier with a 22-pint capacity is the best choice for you. It would be the right choice for you if you want to use it in a large tent or in your home later on. 2. If you don't have any intention of future upgrading the size of your grow tent then I would recommend going with the Afloia Dehumidifier which is one of the lightest dehumidifiers on the market, and is perfect for your small-size grow tent.
