So I've searched around and haven't found any threads pertaining to this yet. I'm finishing up building my grow closet and due to space limitations it will be 2'x2'x8'. Idk if in a space that size a lack of humidity will be an issue or not, BUT if it is possible, has anyone ever tried using a diffuser since they are so small and would fit well into a corner? Also if that would work, if or more like when i run into a pest issue someday, could a few drops of rosemary/neem oil be used in it with the water as a method of pest control? Thanks in advance!
