12 L/day Dehumidifier – Mars Hydro – For Indoor Grow Tents | Smart RJ12 Control | Compatible with the iControl System

Recommendations for using a dehumidifier during different stages of plant growth

♦ 1. Seedling / Early growth stage

      Recommended humidity: 65%–75%
      Directions for use:

• Run the dehumidifier at a low setting or intermittently to prevent the air from becoming too dry.
• Be mindful of high nighttime humidity to prevent diseases caused by damping-off.
• At this stage, stability is more important than rapid dehumidification.

♦ 2. Vegetative growth stage

       Recommended humidity: 55%–65%
       Directions for use:

• Use Auto mode or Constant Humidity mode to maintain a stable environment.
• Use in combination with circulation fans to reduce moisture buildup on the leaves.
• Increase the dehumidification slightly at night when humidity tends to rise.

♦ 3. Flowering stage

       Recommended humidity: 40%–50%
       Directions for use:

• This is the most critical step in using a dehumidifier.
• Continuous or high-power mode is recommended to prevent mold and bud rot.
• Pay special attention to spikes in humidity after the lights are turned off; preventive dehumidification is recommended.

♦ 4. Late flowering / Ripening stage

       Recommended humidity: 35%–45%
       Directions for use:

• Maintaining lower humidity helps improve quality and reduce the risk of mold.
• Avoid large fluctuations in humidity; consistency is more important than pushing levels to extremes.

♦ 5. Drying stage (after harvest)

       Recommended humidity: 45%–55%
       Directions for use:

• Use the dry mode or the low-level continuous dehumidification setting.
• Avoid drying it too quickly, as this could negatively affect the flavor and texture.
• Make sure that the humidity and temperature decrease gradually and evenly.

♦ Additional tips:

• Humidity is generally higher at night than during the day, which makes dehumidification particularly important at night.
• Connecting the dehumidifier to temperature and humidity sensors and a smart controller enables automatic adjustment for greater convenience and energy efficiency.
