Where Is the Best Place to Install Dehumidifiers in Grow Room?

In a grow room, placing the dehumidifier correctly is crucial for maintaining optimal humidity and preventing mold, mildew, or other issues. Here are the best strategies for placing your dehumidifier:

Best Locations for Dehumidifiers in a Grow Room:

Near the Center of the Room

Placing the dehumidifier in the center helps ensure even air circulation and humidity control throughout the room.

Ideally, position it away from walls or corners to allow air to flow freely and let the unit draw in moisture from all directions.

Tip: Ensure the airflow isn't obstructed by plants or equipment.

Close to the Humid Zones

If certain areas of the grow room have higher humidity (such as around irrigation systems or water sources), place the dehumidifier near those spots. Preair ZETA dehumidifiers are ceiling mounted. Installing a grow room dehumidifier above the plants achieves maximum effect.

You may notice some areas with higher moisture from watering or misting, and placing the dehumidifier there will help remove excess moisture from those areas more efficiently.

Away from Vents or Direct Airflow

Direct airflow from vents or fans can reduce the efficiency of the dehumidifier.

Ensure the dehumidifier isn't facing directly into the airflow from an HVAC or fan. The air it pulls in needs to be still to work effectively.

On the Floor, But Elevated

The air near the floor often has the most moisture, but you don't want the unit to be too low to the ground or in a puddle.

Use a small stand to elevate the industrial size dehumidifier a few inches off the floor, which prevents damage from any moisture and ensures better airflow.

Near the Exhaust Vent

If your grow room has an exhaust system, positioning the dehumidifier closer to the exhaust vent can help remove moisture before it has a chance to escape.

This placement ensures the dehumidifier can effectively lower humidity levels before the moist air exits the room.

Considerations for Proper Airflow:

Fans: Use fans to circulate air around the grow room to help the dehumidifier pull in moisture from all directions.

Ventilation: Keep an eye on the ventilation setup, ensuring the dehumidifier doesn't have to work against strong air currents or closed-off areas.

Monitor Humidity Levels:

It's a good idea to use a humidity monitor to track moisture levels in different parts of the room, adjusting the dehumidifier's placement based on the readings.
