Why are air extractors important in indoor growing?
In a closed growing environment, such as a grow tent or indoor room, maintaining stable environmental conditions is essential. Air extractors play a crucial role by removing hot, stale air and introducing fresh air that provides the oxygen and carbon dioxide necessary for photosynthesis and plant respiration. They also help prevent moisture buildup, reducing the risk of fungal and pest infestation.
Benefits of using air extractors
- Temperature regulation: They prevent overheating caused by grow lights, maintaining a suitable temperature for plant growth.
- Humidity control: Reduces excess moisture, minimizing the risk of fungal diseases and creating a healthier environment.
- Air renewal: They ensure a constant supply of fresh air, providing the optimal levels of CO₂ and oxygen that plants need.
- Odor Elimination: When combined with appropriate filters, they help control odors generated during cultivation.
Types of air extractors available
In this category, you will find:
- Axial extractors: Ideal for small spaces or as a backup for fresh air intake. They are economical and easy to install.
- Centrifugal extractors: They offer greater power and pressure, suitable for systems with carbon filters and long ducts. They are effective for extracting air from larger crops.
- Soundproof extractors: Designed to reduce noise, they are perfect for growers looking for discretion without sacrificing efficiency.
How to choose the right extractor?
The choice of extractor depends on the size of the growing space and the specific ventilation needs. It's important to calculate the volume of the area (length x width x height) and multiply it by the number of air changes required per hour, generally between 45 and 60 times. This calculation will give you the minimum flow rate required in cubic meters per hour (m³/h) to maintain an optimal environment.
Frequently Asked Questions about indoor air extractors
Is an air extractor necessary in a small grow room?
Yes, even in small spaces, an extractor fan is essential to maintaining stable and healthy environmental conditions for plants.
Can I use a household fan as an extractor?
It is not recommended, as domestic fans are not designed for efficient air extraction and do not offer the same performance as a specific grow-area extractor.
How can I reduce the noise from the extractor?
Opt for soundproof extractors or use sound-absorbing enclosures and damping systems to minimize vibrations and noise generated during operation.
