The Hydra 'SM' Electronic Humidifier may well be the easiest and best way to keep your stash in optimal condition. This compact unit takes up about as much space as six cigars, yet it can easily handle up to eight cubic foot humidors - that's large enough for 2500 cigars! It uses a 1000mA power supply, meaning that it's one of the most powerful humidifiers in its class. You can check the humidity level on the on-board visual display, or via the included remote (wita a 54" cord) which lets you check or change the humidity level without even opening the box. External fans can be purchased to circulate moisture more efficiently in larger humidors, and extra tanks can be purchased so you always have a tank ready to swap. Finally, you never need to worry about running out of water because the Hydra 'SM' has both visual and audible 'low water' warnings.
