I made a little humidifier using a clean planter, a clean drip tray and a dishtowel draped over the top. Pour water in the tray, so the towel is wicking up the water, aim one of your little circulation fans on it and voila...humids. You can adjust it by moving the fan or turning up the exhaust system. Without it, I'm hanging at 40% or below, with it I'm at 59-61%. Good luck!
