Works for humidity but can also be used to fan your grow too. I'm extremely satisfied with the product and it's a good price too

Works so well we bought a second set of everything!!!

Eliminated my humidity issues. Just couldn't get it dialed in using other methods. Using this product and a timer did the trick.

This Humidifier has boosted the Humidity up 50 %. Worth 20 bucks.

everybody should use it in there grow good humidity
