VPD Pro Standard

The VPD Pro Standard isn't just another humidifier — it's a precision environmental control system built for mid-size sealed rooms.

Most consumer humidifiers fail in a demanding grow. They can't maintain stable humidity, they break down under continuous use, and they lack the integration serious growers need. The Standard solves all of it.

With a 10-gallon reservoir, 20 misting heads, and up to 15 L/hr of ultrasonic output, the Standard keeps up with rooms running as much as 16,000 watts of lights and equipment — roughly a 20 × 15 × 10 ft room at full load. It draws 750W on a dedicated 10A circuit and integrates with popular automation systems to hold your VPD targets automatically.

Better to size up than run short — a unit with headroom hits set point faster and lasts longer. This is our most popular model: the proven workhorse serious growers depend on day after day.
