VPD Pro XL

The VPD Pro XL isn't just another humidifier — it's a precision environmental control system built for the largest sealed rooms.

Most consumer humidifiers fall apart in a serious grow. They can't hold a stable humidity level, they quit under continuous use, and they can't talk to your automation. The XL fixes all of it.

With a 30-gallon reservoir, 36 misting heads, and up to 27 L/hr of ultrasonic output, the XL keeps up with rooms running as much as 30,000 watts of lights and equipment — think a room around 40 × 15 × 10 ft at full load. It draws 1,300W on a dedicated 15A circuit and integrates with popular automation systems, so you dial in your VPD targets and let it hold them.

When in doubt, size up. An oversized unit reaches set point faster and lasts longer than an underpowered one that never quite gets there. For the biggest rooms, the XL is the humidifier you buy once and depend on for years.
