Since my other preferred cheap ultrasonic humidifier was sold out when recommending an option to a new mushroom grower, I decided to check this out. What attracted me to this was the features of the ultrasonic humidification, the large reservoir, and the dual nozzle (directing the humidity to more places with less effort is always nice) setup. What I was also intrigued by was the built in hygrometer, controlling the humidity levels is something that we often rely on InkBird style devices (or similar) for, but I am always happy to remove extra equipment and have less cables/potential failures in the mix.
I’ve used mine for over a year, and liked it so much I’ve purchased a second one. I’ve used the heating feature as well, which produces a warm vapor mist, and has been helpful in cooler times to get the humidity higher than with the ultrasonic humidification alone. I do use additional electric hygrometers alongside the built in unit, it’s remained spot on.
When pinning mushrooms, I like to keep the humidity as high as possible. When fruiting (after pins have formed), I like to back humidity off to around 60-70% RH to avoid issues with blotch or other issues related to excess humidity. By setting the humidifier to around 60-70% at fruiting, it runs less frequently, less water is used and happier mushrooms are grown. Be sure to manage airflow with humidity to avoid drying mushrooms out, some grows require 24×7 humidity due to intense fresh air requirements, but this is usually reserved for commercial grows.
