AC Infinity Cloudforge Plant Humidifiers — VPD & Humidity Control

About

Adding humidity is the easy half. Holding it steady is the part that matters, and it's where a plant humidifier differs from a household one. The Cloudforge series uses an EC ultrasonic vaporiser with 10 output levels and a corded humidity sensor, so instead of running flat out until the tank empties it holds a target you set — by humidity, or by VPD. Quick Bloom Lights is the official Australian AC Infinity importer: stocked in Sydney, Australian plug fitted, 2-year warranty handled here. 240 / 1,300 ml per hour — T3 and T7 10 levels PWM output, not on/off VPD control triggers on humidity or VPD Cold mist no warm-up, no heat added T3 or T7? Same technology, same controls. The difference is output — and output, not tank size, is what decides which one suits your space.

The tank is there to feed a much larger vaporiser. What that buys is the ability to actually lift and hold humidity in a big room, where a smaller unit would run continuously and still fall short. If your space is large, size up on output; a bigger humidifier throttled back holds a target far better than a small one at maximum. Why humidity, and why VPD Plants transpire through their leaves, and how readily they do it depends on the difference between the moisture in the leaf and the moisture in the air around it. That difference is vapour pressure deficit — VPD. Air that's too dry pulls moisture out faster than the roots can repl
