We recently added the VPD Pro's largest humidifier system to our veg. We are very pleased to say the least! The system keeps our VPD exactly at the numbers we're trying to reach! We have never been able to run our lights at 100% due to drying out the room. But that is not the case anymore thanks to the guys at VPD Pro!!! Our plants have doubled within a week of installation!

Replaced five pieces of equipment, saved power, and am living between 0.8 under to 0.1 over set point.

VPD Pros earned the Breakout Brand of the Year award in the 2025 Best of Herbage because they've brought real innovation to cultivation environments. Their technology helps growers dial in vapor pressure deficit with precision, giving cultivators a smarter way to stabilize plant health and maximize quality. In a market where consistency matters more than hype, tools like this are making a real difference.

VPD Pro's humidifiers outperform every humidifier that I have used in the past. Keeps my rooms at perfect humidity levels. I recommend them to anyone that is having a hard time maintaining their VPD.
