A 4.5L plant humidifier designed to provide controlled moisture delivery in grow tents, grow rooms, greenhouses, and other growing spaces. Its onboard controller uses a corded sensor probe to monitor conditions and manage humidity and VPD-based operation.
The EC ultrasonic vaporizer offers 10 output levels for precise moisture control. Extendable tubing supports targeted vapor distribution, while automated programming, low-water shutoff, backup memory, and a hidable display help maintain consistent operation.
Key Features
-
10-Level Moisture Control: The EC ultrasonic vaporizer digitally pulses water and offers 10 output levels for fine-tuned humidity control.
-
Humidity Trigger: AUTO Mode activates the humidifier when the sensor reading falls below the selected humidity threshold.
-
VPD Trigger: VPD Mode activates the humidifier when the measured VPD reaches or exceeds the selected threshold.
-
Timer and Cycle Programming: TIMER Mode runs the humidifier for a selected countdown period, while CYCLE Mode continuously alternates between programmed on and off durations.
-
Precision Sensor Probe: The corded sensor uses a Swiss-made thermal alloy sensor with an SAE grade-316 steel waterproof gasket for localized temperature, humidity, and VPD readings.
-
Targeted Vapor Delivery: The flexible hose extends to over 4 ft. to direct moisture toward specific areas within a growing space.
-
Water-Resistant Design: A specially designed seal helps prevent water tank leakage, while waterproof connection ports protect against moisture when connecting compatible controllers.
-
Automatic Low-Water Shutoff: Operation pauses when the water supply is depleted and resumes after the tank is replenished.
-
Tilt Fail-Safe: Programming pauses if the unit falls or tilts past a 20° angle and resumes when it is returned to an upright position.
-
Hidable Backlit Display: The display can be switched off while programmed functions continue running in the background.
-
Backup Memory: Auto-start with backup memory helps retain operation after power interruptions.
-
Calibration Settings: Supports temperature, relative humidity, and leaf-offset calibration.
-
Controller Lock: Locks the current mode to prevent accidental setting changes.
-
UIS Integration: Connection to a compatible UIS controller provides access to expanded climate programming, grow cycles, schedules, app control, automation, and data charts.
