The Humidifier is a device that speeds up the production of Funghi.

Original GameEdit

The original game has 10 different levels of Humidifiers.


Mushroom Garden Seasons has four different Humidifiers for each season, currently totalling 20.


Mushroom Garden Deluxe currently has 18 Humidifiers, (10 similar to those in the original game) with all after the first 10 having been added through events, with most of them being unlockable through the completion of event related requests or through secret word. It is presently unknown how the effectiveness of those outside the first 10 compare to each other. Currently, a list of the requests or secret words needed to unlock all of them is not present. The Ultimate Humidifier (+40%) is the best in the game, with the Bat Humidifier (+36%) being second best.
