I have a humidity problem when the lights go off, it rises to 80%. I made this mini dehumidifier with coarse salt and I should mention that during the dark hours I have a fan and a humidity extractor running, but it doesn't drop enough... Any advice? Suggestions?

Use some salt or rice but they will not do so much. Let the air ricirculate in to the room you are growing. I think u need a dehumidifier in italy now is very humid , i can flower only cause i use my ac to drop down the humidity in the night, in the day i can open the window and the humidity drops down. Hope tu help u, my english is bad tells me if u want some tips in italian 😊💪🏼

hi green thumb, what's the outside humidity? if it's at 80 you have little to do. if it's lower, you just need to turn the extractor up to the max and ventilate the inside of the grow as best as you can. passive dehumidifiers (like the one you built) are very inefficient. active dehumidifiers consume a lot of power and generate a lot of heat.
