An AC Infinity ultrasonic humidifier connected to the Controller 69 to automatically maintain target humidity levels in the propagation or grow space.
Dakota installs the CloudForge T7 in the propagation room after dealing with consistently low humidity (below 64% RH). He sets the Controller 69 to trigger the humidifier at 70% RH, noting that runoff water from the Terraform 7 AC unit can be fed directly into the humidifier reservoir.
