Spider Farmer 5L Cool Mist Humidifier

The Spider Farmer 5L Smart Cool Mist Humidifier provides high-efficiency climate control tailored specifically for indoor grow tents, greenhouses, and cultivation rooms. Dry grow tent air forces plants into defensive transpiration, leading to stunted leaf expansion, crisping, and poor nutrient uptake. By maintaining ideal relative humidity (RH) and Vapor Pressure Deficit (VPD), this smart humidifier supports vigorous early vegetative growth, stronger root development, and healthier crop yields.

Equipped with a flexible, extendable forked misting hose, the unit allows growers to direct fine ultrasonic mist exactly where it is needed near the canopy without sitting the humidifier base directly inside the grow space. The system includes an advanced GGS Temperature, Humidity, and Light Sensor that tracks ambient conditions alongside day/night lighting cycles in real time. Through full integration with the Spider Farmer GGS Smart App, growers can monitor environmental metrics remotely, program automated humidity targets, and set custom schedules directly from a smartphone.

Featuring a 5-litre reservoir and near-silent operation, this unit delivers consistent, long-duration mist output suitable for compact grow tents up to medium-sized grow rooms. By automating humidity based on live sensor feedback, it eliminates sudden RH spikes and dry spells, establishing the perfect microclimate for plants across all growth stages.

Pro-Tip: Position the GGS environmental sensor at canopy height—away from the direct blast of the extension hose—to ensure the unit measures true ambient humidity rather than localized mist output. Use reverse osmosis (RO) or distilled water to prevent mineral dust deposits on plant leaves and grow lights.

Key Benefits:

• Spider Farmer GGS App Integration: Connects seamlessly with the GGS ecosystem for remote smartphone monitoring, custom scheduling, and automated humidity control.

• Included GGS Temp/Humidity/Light Sensor: Tracks ambient temperature, relative humidity, and day/night lighting cycles for precise climate automation.

• Targeted Forked Hose Extension: Flexible, extendable tubing routes cool mist directly into grow tent canopies or specific plant clusters.

• Quiet 5L Cool Mist Capacity: Generous 5-litre tank provides continuous, ultra-quiet misting to eliminate dry air stress in grow spaces.

• Optimized Crop Health & VPD: Maintains target humidity levels to boost stomatal opening, improve nutrient uptake, and prevent leaf tip burn.

• Flexible Placement: Keeps the main water tank outside or on the floor of the grow tent to maximize usable canopy floor space.
