I am considering buying a humidifier for my grow area, mainly because of the very low humidity even with trays. The thing is, I don't really know what to look for. I know I want a personal humidifier, as my grow area is not that large, and a small tank size won't put me off any because I can refill it 10 feet away. There are alot of options, and I don't even know if I should get a cool or warm mist humidifier. Any advice would be welcome.
