Features of Dehumidifier

Click to check more details

Powered by a high-performance compressor, the unit removes up to 12 L/day. Dual ventilation ports create a closed-loop airflow, improving dehumidification efficiency and air circulation in grow tents. Ideal for high-humidity environments, helping stabilize humidity and optimize plant growth. Recommended for grow tents up to 150 × 150 cm.

Seamlessly integrates with smart controllers to automatically adjust humidity in real time, working in coordination with temperature control to maintain optimal VPD across all growth stages, from seedling to harvest. This reduces manual intervention and ensures a consistently stable grow environment.

Supports both water tank drainage and drain hose connection, providing flexibility for short-term use or long-term automated operation. When the tank reaches full capacity, the unit automatically stops and activates a warning indicator to prevent overflow, ensuring safe and reliable operation.

Equipped with automatic defrost and anti-freeze protection, the unit switches to defrost mode in low-temperature conditions to prevent coil icing and ensure stable performance. Power-off and restart memory allows the unit to resume previous settings after a power interruption, while sensor fault alerts provide timely warnings for abnormal conditions.

  • HOLD Mode: Automatic humidity-hold mode for maintaining stable daily grow conditions.

  • CONT Mode: Full-power continuous dehumidification for rapid humidity reduction.

  • DRY Mode: Enhanced drying mode for fast drying of crops, clothing, or enclosed spaces.

  • FAN Mode: Ventilation-only fan mode for air circulation without dehumidification.

  • A built-in 24-hour timer enables scheduled on/off control for greater convenience and energy efficiency.

Equipped with four smooth-rolling casters for effortless movement without lifting, along with an ergonomic handle that makes positioning, adjustment, and routine maintenance simple and convenient.

Using Tips

Dehumidifier Usage Recommendations for Different Plant Growth Stages

1. Seedling / Early Growth Stage

  • Recommended Humidity: 65%–75%
  • Usage Tips:
    • Run the dehumidifier at a low setting or intermittently to avoid overly dry air.
    • Pay attention to high nighttime humidity to prevent damping-off diseases.
    • Stability is more important than rapid dehumidification at this stage.

2. Vegetative Growth Stage

  • Recommended Humidity: 55%–65%
  • Usage Tips:
    • Use Auto or Constant Humidity mode to maintain a stable environment.
    • Combine with circulation fans to reduce moisture buildup on leaves.
    • Increase dehumidification slightly at night when humidity tends to rise.

3. Flowering Stage

  • Recommended Humidity: 40%–50%
  • Usage Tips:
    • This is the most critical stage for dehumidifier use.
    • Continuous or high-power mode is recommended to prevent mold and bud rot.
    • Pay special attention to humidity spikes after lights turn off; pre-emptive dehumidification is advised.

4. Late Flowering / Maturation Stage

  • Recommended Humidity: 35%–45%
  • Usage Tips:
    • Maintaining lower humidity helps improve quality and reduce mold risk.
    • Avoid large humidity fluctuations; consistency is more important than pushing extreme low levels.

5. Drying Stage (Post-Harvest)

  • Recommended Humidity: 45%–55%
  • Usage Tips:
    • Use Dry mode or low-level continuous dehumidification.
    • Avoid drying too quickly, as it may negatively affect flavor and structure.
    • Ensure humidity and temperature decrease gradually and evenly.

Additional Tips:

  • Nighttime humidity is usually higher than daytime, making dehumidification especially important at night.
  • Pairing the dehumidifier with temperature & humidity sensors and a smart controller enables automatic adjustment for greater convenience and energy efficiency.
