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.
Hello... my name is Snick Meyers and I am an owner of Trio Pharms, LLC. Over the past four months, Trio has served as a somewhat "beta test site" for a humidifier known as the VPD Pro. I have long been aware of the vapor pressure deficit chart and its relationship to growing marijuana. Previously, Trio had problems generating enough moisture to stay within the boundaries that the VPD chart recommends vs room temperature. I found humidifiers that promised they could fix this problem but they came at a price tag that was unaffordable to our meager budget.
The VPD Pro solves this budget problem... but does it perform as promised... "in spades!"
By electronically charting the 24 hour deviation of this humidifier, I found that it is accurately calibrated to a tenth of one percentage point over the 24 hour period. Because the machine can produce more moisture than our room requires, it allows us to turn up the air conditioning; thereby, saving us money on our electric bill while still operating in the prime vapor pressure deficit range that the chart indicates.
However, the biggest surprise to me was that the increased moisture had a greater positive effect on marjiuana growth, in my opinion, than the usage of CO2... yet another reduction in cost!
Needless to say, Trio does not only recommend the VPD Pro but has it installed in all of our grow rooms.
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.
