besides the obvious dehumidifier...Sealing the res as best you can it's the only water in the room most likely so without that leakin the air should get pretty dry especially with lights on...humidity shouldn't be a serious problem if you have adequate ventilation...I've heard of people using dehumidifiers in flower to help resin production but never during veg cause it is a tropical plant

What % humidity are you running at currently?
