DIY Humidifier Accessories & Fans

Everything you need to build and automate your own ultrasonic fog humidifier. These accessories turn any House of Hydro mist maker into a complete, hands-off humidification system for grow tents, greenhouses, mushroom fruiting rooms, reptile enclosures, and whole-home setups.

Add a waterproof fan kit to push fog where you need it, a humidistat controller to hold humidity automatically within a few percent of target, and the mist output controller to dial fog volume up or down. The auto-fill float valve keeps your reservoir topped off for unattended runs, the UV reservoir sterilizer keeps water clean between refills, and the splash guard and duct adapter help you fine-tune placement and airflow.

New to building your own? Start with our DIY humidifier build guide, or pair these with a mist maker kit to get fogging in about 30 minutes.
