Check out my humidification setup. I installed a water-filter that runs from a hose-spigot into the grow-tent where it branches into several individually-controlled tubes that feed each of my humidifiers.
I built and installed a second DIY bucket-ultrasonic from a cat-litter bucket and old computer fan that works better than the $40 ultrasonic I ordered on Amazon. So now the grow-room is fully equipped with 2 (soon-to-be 3) free-standing ultrasonics, 1 inline duct-ultrasonic, and an air-stone bucket-humidifier.
