Greenhouse Dehumidification Technology for Cannabis Cultivation

Dehumidifiers eliminate humidity issues in cannabis growing

Dehumidification for Cannabis Cultivation

Indoor Agriculture

In an endeavour to create the optimal environment, indoor agriculture can encounter certain challenges in climate regulation including humidity levels.

As the Medical Marijuana industry grows in Australia and the world, it is important to understand how humidity can affect cannabis as it is extremely sensitive to humidity.

Cannabis is susceptible to a variety of humidity-related diseases such as botrytis, downy mildew and Alternaria.

Treating humidity in the growing and drying spaces with a dehumidifier for cannabis is the most efficient method to eliminate diseases.

How to Grow Medicinal Cannabis

indoor cannabis farming australia

Many medicinal cannabis growers maintain that soil and nutrients are the most important factors in growing cannabis, however it is environmental conditions that really matter.

Light, temperature, air circulation, light reflection and humidity are the main factors for creating a perfect growing environment.

To enable a year-round yield, the grow room must maintain a consistent climate.  Temperature and humidity are essential factors during growth cycles.

HVAC Systems and Hydroponics

A number of factors play a role in controlling humidity: room temperature, room size, number of plants, plant species and air circulation. But, ultimately, nearly every indoor grower, no matter how small or large the application, is going to need a dehumidifier or humidifier to achieve indoor air quality.

When you are about to start your cannabis production facility design, have a chat to us as we have worked with Queensland medicinal cannabis growers and can help you create the ideal indoor climate for medicinal cannabis cultivation and manufacture.

  • Whether growing in a greenhouse or closed facility, plants constantly transpire water, increasing humidity. If left unchecked relative humidity will quickly increase.

  • The dew point is reached once water vapour saturates the air. Water starts to condense on the cooler surfaces, including the plants and inside the buds. This condensation leads to the development of fungal pathogens, which leads to the spread of disease and bud rot.

What is the ideal Relative Humidity for MEDICINAL Cannabis?

The relative humidity that is best for cannabis plants varies over the course of their lifecycle. RH levels should be changed during different cycles to optimise growth and health.

It is also important to note that the optimal relative humidity depends on the plant’s heritage. If a plant is native to the tropics, then it can handle a higher RH than a plant native to cooler climates.

Benefits of a dehumidifier for cannabis growing and drying

Dehumidifiers simultaneously improve grow quality, increase dry weight mass, and stimulates the manufacture of compounds.  There are two types of common dehumidifiers that can be applied, depending on a few variables; a desiccant dehumidifier or a refrigerant dehumidifier.
