try putting some wet rags in there and maybe a few paper towels in the cups to help give the water something to wick up and evaporate off of.my humidity is 30%....f@$# i tryed putting a couple cups of water next to my plants with a heating pad underneath and nothin changed. do i need a humidifier? is there a cheaper way? how do i keep the humidity up in my box if im constantly pushing fresh air in?
rags worked pretty well for me here in the states, mate. and i never had problems with water and electronics, thats only for the clumsy and unbalanced.
do you have the humidifier running continuously
