Description

High-precision plant dehumidifier designed to fine-tune minor humidity and VPD changes in grow tents up to 2x2 (one plant).

Integrated onboard controller with corded sensor delivers VPD and humidity readings, trigger-based automation, timers, cycles, and auto shutoff when full.

Dual thermoelectric motors and 10-level PWM control support humidity adjustment. The manufacturer describes control down to 60% RH; follow the setup and operating conditions below.

Exhaust port enables ducting of dry air into a grow tent, while the optional intake port supports an ultra-efficient, closed-loop humidity control system.

Works with UIS controllers for Wi-Fi app connectivity, unlocking AI-powered automations, data tracking, real-time alerts, and personalized grow guides.

Precision Climate Control: Purpose-built for cultivation environments, this plant dehumidifier is designed to help fine-tune minor humidity and VPD changes from propagation through flowering in grow tents up to 2x2 (one plant). The manufacturer describes 0.6-1.0 kPa as an optimal VPD context to support transpiration, plant metabolism, nutrient uptake, and growth. Actual results depend on growing conditions, installation, and the selected programming.

Advanced Engineering: Driven by dual thermoelectric cooling modules and 10-level pulse-width modulation (PWM) control, the unit is designed to fine-tune relative humidity. The manufacturer describes control down to 60% RH; use the listed operating and setup conditions. A rear-mounted exhaust port allows direct ducting of dry air into cultivation zones, while the optional intake port supports a closed-loop configuration for sealed environments where climate precision and energy efficiency are important.

Integrated Smart Control: The integrated controller, paired with a high-precision remote sensor, continuously monitors live VPD and RH metrics while enabling automation logic through programmable thresholds, timed cycles, and auto shutoff upon reservoir fill. Fully compatible with UIS platform controllers and the AC Infinity mobile app, the system offers full wireless control and monitoring. When connected to the controller AI+, users gain access to AI-driven automation routines, historical environmental data logging, real-time push alerts, and adaptive grow recipes-enabling optimized environmental management from any location.

Setup and operating conditions

Use up to two optional 4-inch duct tubes, sold separately. Close the loop for dehumidification or use an open intake/exhaust route in FAN mode. Keep unused ports capped, place the sensor at canopy height and keep the unit upright. A missing or full condensation tank pauses operation, as does tilting past 20°. Empty the tank or connect the supplied drain pipe to a suitable catch tray or drain. Set OFF mode before unplugging and cleaning with a damp cloth; let parts dry. Do not hardwire the unit or use it in flammable, explosive, chemical-laden or wet surroundings.

Connecting a compatible external UIS controller, sold separately, overrides onboard settings and disables the onboard touch controls and display. OFF sets the minimum running level; choose zero for a complete stop when triggered off. ON sets the maximum; AUTO responds to high humidity and VPD mode to low VPD. Refer to the HYDRONE3 programming section for timers, cycles, calibration and leaf offset.
