HOW IMPORTANT IS PROPER VENTILATION FOR INDOOR CANNABIS CULTIVATION?



According to the "U.S. Cannabis Market Size, Share & Growth Report" by Grand View Research, the size of the cannabis market in the United States was valued at $13.2 billion in 2022 and is expected to grow at a compound annual growth rate of 14.2% from 2023 to 2030.

In the United States, cannabis is widely used in the cosmetic, pharmaceutical, and food and beverage industries. It is also recognized as effective for the treatment of various chronic conditions. The U.S. Food and Drug Administration (FDA) has approved its use in pharmaceutical products for the treatment of seizures and chemotherapy-induced side effects.

Furthermore, in December 2020, the U.S. House of Representatives approved legislation to remove cannabis from the "Controlled Substance Act of 1970," and it is expected that this further "liberalization" will create huge market growth opportunities in the coming years (source: Grand View Research).

It is evident, therefore, that indoor cannabis cultivation is gaining more and more popularity due to the ability to provide plants with a controlled environment for optimal growth. However, to achieve a healthy and high-quality harvest, it is essential to understand and properly manage the key factors that influence indoor growth. During the cannabis growth cycle, it is important to provide suitable environmental conditions for each specific phase; for example, the flowering phase requires a specific light photoperiod to develop flowers.

Among these factors, VENTILATION plays a crucial role in controlling temperature and humidity to ensure a stable and ideal environment for cultivation and to obtain a high-quality cannabis harvest.

Investing in an adequate ventilation system is, therefore, essential for indoor cultivation, especially for cultivations that use grow rooms (closed and controlled environments used primarily in indoor agriculture and widely employed in cannabis cultivation and other plants that require a carefully managed environment to thrive). Grow rooms need a controlled environment that ensures proper distribution of carbon dioxide (one of the main requirements every plant needs to grow well).

Let's see together the most important factors for Indoor Cannabis Cultivation:

  • Lighting: Light is one of the most critical factors for cannabis plant growth. In grow rooms, plants cannot benefit from natural sunlight, so it is essential to provide adequate lighting. LED lights are commonly used because they offer a broad spectrum of light, ideal for photosynthesis and proper plant development during different growth stages.
  • Temperature: Cannabis thrives in a specific temperature range. During the day, the ideal temperature should be between 20°C and 30°C, while it can be slightly cooler during the night. Maintaining a stable and constant temperature is crucial to avoid stress on the plants and promote healthy growth. Good ventilation facilitates proper air exchange, helping to dissipate the heat generated by lamps and air conditioning systems. This helps to maintain a constant and optimal temperature for plant growth, avoiding heat spikes that could damage the plants.
  • Humidity: Air humidity is another critical aspect of indoor cannabis cultivation. During germination and the early stages of growth, humidity should be kept around 70-80%. As the plants grow, humidity can be gradually reduced, reaching 40-50% during the flowering phase.

Proper VENTILATION helps prevent excessive humidity inside the grow room.

During their growth, cannabis plants start to produce and release water, which is why the resulting humidity needs to be removed from the grow room to prevent it from becoming excessive. Good air circulation helps reduce humidity levels, avoiding mold formation and root rot, common issues in environments with high humidity.

  • CO2 Supply: CO2 is essential for plant photosynthesis, and proper ventilation ensures that plants receive the necessary amount of CO2.
  • Odor Reduction: Ventilation helps reduce unpleasant odors produced by cannabis during the flowering phase. Well-designed ventilation systems can help control the diffusion of these odors outside the cultivation environment.

The ELITURBO range is the ideal proposal for this type of cultivation to achieve maximized and high-quality harvests while also saving on energy costs.

Eliturbo produces a long horizontal air throw (up to 10 m.) and thanks to the alternating rotation of the special patented impeller, it ensures a great air circulation and horizontal distribution of heat and humidity throughout the environment without the need for air transport ducts.

ELITURBO is an international IMPRESIND patent and guarantees several advantages for use in indoor greenhouses, including:

  • Improves efficiency for heating, cooling, or drying up to 50%
  • Stabilizes the microclimate of grow rooms
  • Reduces mold and disease problems due to excessive humidity
  • Enhances plant yield through increased CO2 contact
