Can You Put a Dehumidifier in a Grow Room?

Put a greenhouse dehumidifier in a grow room

It is common and beneficial to use a dehumidifier in a grow room. Controlling humidity levels is crucial for the success of many indoor growing operations, as high humidity can create an environment that promotes the growth of mold, mildew, and other undesirable pathogens.

A dehumidifier helps reduce excess moisture in the air by extracting water vapor and collecting it in a reservoir or draining it directly. By maintaining optimal humidity levels, typically between 45% and 55% relative humidity (RH) during the vegetative stage and slightly lower, around 40% to 50% RH, during the flowering stage, you can create a more favorable environment for plant growth. If you are in face of the humidity problem, please contact Preair for a dehumidification scheme.

Different growth requirements for humidity

If you grow vegetables in your grow rooms, You need to know the growth conditions of vegetables. The humidity condition in the greenhouse is directly related to the growth and development of various crops. Scientific and reasonable control of the humidity condition in the greenhouse can make the greenhouse form a small environment conducive to the growth and development of fruits and vegetables, which is an important link to ensure high yield, quality and high efficiency in the greenhouse. Different stages of crop growth and development have different requirements for air humidity. For example, cucumbers belong to moist vegetables and require air humidity of around 85% -90% RH. Luffa, bitter gourd, and other semi humid vegetables require an air humidity of around 70% -80% RH. Solanaceae and legumes are semi dry vegetables, and the required air humidity is around 55% -65% RH. Watermelons, cantaloupes, etc. belong to the dry type, and the required air humidity is around 45% -55% RH.

Suggestion of proper greenhouse dehumidifiers

Different types of dehumidifiers are available, such as refrigerant dehumidifiers, desiccant dehumidifiers, or whole room dehumidifiers. The specific type and capacity of dehumidifier you choose will depend on the size of your grow room and the level of humidity you need to control.

Remember to monitor humidity levels regularly using a hygrometer and adjust the dehumidifier settings accordingly. It's also important to ensure proper ventilation in your grow room to maintain a healthy airflow and prevent stagnant conditions.
