Control the Indoor Grow Environment
To produce higher yields and healthier crops

Controlling humidity indoors helps ensure healthy plants. That’s because the amount of moisture in the air effects how much water plants drink and whether they drink more from their roots or their leaves. When there’s too much or too little water in the air at different growth stages, it impacts progress and nutrient intake. For example, too much humidity can cause white powdery mildew or rot/mold and too little humidity can cause nutrient problems such as nutrient burn.
Managing humidity really means controlling relative humidity (RH) an indicator of how much moisture is in the air and how it’s impacted by temperature. A simple definition of relative humidity is the amount of moisture contained in the air compared to the maximum amount the air could hold at the same temperature.
EnviroBoss iSeries smart dehumidifiers provide decision-driving information you need to optimize your environment’s humidity. For example, you can quickly get inlet and outlet temperature and RH readings (show visual example). And iSeries dehus have built-in humidistats. You can set the humidistat for a target RH - no other dehumidifier offers this kind of onboard intelligence!

Plus, EnviroBoss iSeries dehumidifiers are manufactured by Dri-Eaz, the leader in commercial drying equipment technology and solutions for over 38 years. With EnviroBoss, you get all the quality, high performance, durability and user-friendly features that other industry professionals rely on.
The humidistat functions like a home thermostat. You set the desired RH percentage. When the atmosphere of the room reaches slightly below the RH% setting, the dehu will cease dehumidifying until the room's atmosphere increases to slightly above the setting. Then the dehumidifier will cycle on and off to maintain the RH setting.
Primarily, warm air holds more moisture than cold air. Therefore, temperature changes impact how much water the air holds – so it impacts humidity.
Move from the highest humidity during the early growing stages, to lower humidity.

  • 70-80% RH for seedlings and clones –a higher humidity level supports water intake through leaves because the root system is still developing.
  • 40-70% RH during the vegetation period – as roots grow and evaporate moisture through their leaves, it’s time to begin to reduce humidity. Around 5% a week is recommended.
  • 40-50% Rh during flowering – ease the humidity down to slightly lower levels.
  • 30-40% Rh during late flowering – lower humidity even more for optimal yield, appearance and quality.
Plants both drink in water AND evaporate water (via leaves to cool plants). So dehumidification requirements depend on many factors, but it isn’t too complicated. How to Choose the Right Dehumidifier
Airmovers like the EnviroBoss LP help keep airflow low to the ground and the EnviroBoss AV helps with evaporation, cooling and air circulation.
