Precision VPD & Moisture Control Engineered for Indoor Cultivation

Eliminate dry air stress, stunted transpiration, and erratic humidity swings across your indoor garden with the AC Infinity CLOUDFORGE T3 Environmental Plant Humidifier – 4.5 Liters (Model AC-CFT3). Engineered from the ground up by AC Infinity specifically for hydroponic grow tents, propagation domes, and enclosed greenhouses, this compact 4.5-liter (1.18-gallon) environmental humidifier delivers up to 45 hours of continuous runtime per refill. Operating at a whisper-quiet 38 dBA with a steady output rate of 8.11 fl oz/hr, the CLOUDFORGE T3 maintains exact moisture targets from delicate seedling and cloning stages through vigorous vegetative growth.

Next-Gen EC Ultrasonic Vaporizer with 10 Precision Output Levels

Unlike conventional household humidifiers that flood rooms with uncontrolled mist or burn out quickly in high-humidity grow environments, the CLOUDFORGE T3 utilizes an advanced Electronically Commutated (EC) ultrasonic vaporizer. By digitally pulsing water at high frequencies, it produces a super-fine, uniform vapor across 10 distinct condensation output levels. This fine-tuned modulation prevents water droplets from pooling on foliage while ensuring smooth, consistent moisture dispersion without jarring humidity spikes.

Onboard VPD & Humidity Triggers with Corded Sensor Probe

Take full command of your microclimate directly from the onboard LED touch interface or remotely through the AC Infinity UIS™ smart ecosystem. Equipped with a high-precision, corded Swiss-made thermal alloy sensor probe, the controller monitors internal tent conditions in real time and automatically activates vapor output based on custom Vapor Pressure Deficit (VPD) triggers, relative humidity (RH) thresholds, timers, or cycle schedules. When connected to an AC Infinity smart controller—such as the flagship CLOUDCOM™ AI touchscreen system—you unlock WiFi app automation, historical VPD graphing, mobile alerts, and synchronized coordination with your inline exhaust fans and grow lights.

External Tent Placement & Extendable 4+ Foot Targeting Tubing

Maximize your valuable floor space inside 2×2, 2×4, 3×3, and 4×4 grow tents. The CLOUDFORGE T3 includes an extendable flexible output hose reaching over 4 feet in length along with interchangeable nozzle attachments. Simply position the humidifier outside your tent, route the flexible tubing and corded sensor probe through a duct port, and direct ultra-fine moisture precisely over your canopy or propagation trays.

No-Leak Sealed Construction & Night-Cycle Safe Display

Built for long-term reliability, the CLOUDFORGE T3 features a specially engineered water-resistant internal seal and waterproof UIS ports to prevent tank leakage and protect electronics. Its backlit digital display can be toggled completely off during dark periods to prevent light leaks from disrupting sensitive photoperiod cycles, while a built-in water-depletion auto-shutoff and backup memory protect the unit and preserve your settings after power interruptions.
