The Spider Farmer SF-Humidifier5 5L Cool Mist Humidifier is a smart ultrasonic humidifier designed specifically for grow tents, propagation setups, greenhouses, and indoor cultivation environments where precise humidity control is essential for healthy plant growth.

Featuring a large 5-litre water tank, this humidifier provides long-lasting cool mist output with ultra-quiet operation, making it ideal for seedlings, clones, vegetative growth, and maintaining stable VPD levels throughout the grow cycle. The unit includes a temperature and humidity sensor probe for more accurate environmental monitoring and automated humidity management.

The extendable targeting hose allows growers to direct mist exactly where it’s needed while keeping the humidifier outside the grow tent to save internal space and reduce clutter. Integrated WiFi and GGS smart control compatibility allows app-based scheduling, humidity targeting, and automation when connected to compatible Spider Farmer systems.

With adjustable mist levels, timer functions, auto shut-off protection, and whisper-quiet ultrasonic operation, this humidifier is ideal for maintaining stable humidity conditions in professional and hobby grow setups alike.
