Grow Tent Fans

Maximise your hydroponic garden’s potential with our quality grow tent fans

Creating an optimal growing environment is crucial for the success of your hydroponic garden. One of the key components in achieving this is ensuring proper air circulation and ventilation. Grow tent fans play a pivotal role in maintaining the right conditions for your plants to thrive:

Control temperature: Grow lights can produce a significant amount of heat, which can lead to high temperatures inside your grow tent. Fans help regulate the temperature, ensuring it stays within the optimal range for plant growth.

Humidity regulation: Maintaining the right humidity level prevents excess moisture, mould, mildew, and other fungal diseases. Fans help distribute moisture evenly, preventing the formation of humid pockets.

CO2 distribution: Plants need carbon dioxide (CO2) for photosynthesis. Fans ensure that CO2 is evenly distributed throughout the grow tent, maximising plant growth.

Strengthening plants: A gentle breeze helps to mimic natural outdoor conditions, which can strengthen plant stems and promote robust growth.

At Hydrocentre Hydroponics, we offer a huge range of fans for grow tents, including premium designs from brands like Allvent, Mistral, Mountain Air, and more. Shop the range online or in-store — we offer fast and affordable shipping nationwide.

Types of hydroponic fans in our collection

We stock several types of fans that can be used in a grow tent, each serving a specific purpose. Here’s a quick breakdown of their uses and advantages in hydroponic grow rooms.

Inline fans

• Inline fans are designed to be installed within ventilation systems. They are powerful and efficient, making them ideal for larger grow rooms. Inline fans exhaust hot air from the grow tent and bring fresh air in.
• Pros: High powered and efficient air exchange.
• Cons: Can be noisy and requires ducting installation. Inline fans can't be used with carbon filers but centrifugal fans and EC type fans can deal with the drop in pressure carbon filters create
• Bonus tip: Install inline fans within your ducting system, ensuring they are securely fastened. Use duct clamps to prevent air leaks.

Oscillating fans

• Oscillating fans are mounted inside the grow tent and move back and forth, providing consistent air circulation. They are essential for preventing hot spots and ensuring even air distribution.
• Pros: Provides consistent air movement, easy to install, and helps strengthen plants.
• Cons: Limited coverage area, may need multiple units for larger tents.
• Bonus tip: Position oscillating fans at different heights to distribute air evenly. Mount them securely to avoid vibrations.

Clip-on fans

• Clip fans are small, portable fans that can be attached to the poles of a grow tent. They are convenient for targeting specific areas and providing additional airflow where needed.
• Pros: Easy to move and position, affordable, and fantastic for small grow tents.
• Cons: Limited power, may not be suitable for larger setups.
• Bonus tip: Place clip-on fans strategically around your plants, focusing on areas that need additional airflow.

Electronically Commutated (EC) fans

• EC fans, such as Headwind and Phresh Hyperfans, which are compatible with carbon filters, feature controllers that adjust speed to maintain the ideal temperature or humidity levels. These fans are essential, high-value products and should be prominently featured for customers outfitting their grow rooms and grow tents.
• Pros: Energy efficient, variable speed control and longer lifespan.
• Cons: EC fans can make them more complex to install and integrate into existing systems than originally. designed for EC technology

Centrifugal fans

• A centrifugal fan, also known as a blower, uses the centrifugal force generated by a rotating disk with blades to move air radially from the centre of the fan to the outer edge. This design allows the fan to produce high pressure and move air over long distances through ductwork.
• Pros: Designed to move a significant volume of air efficiently, ideal for optimal growing conditions in larger or more complex grow tent setups.
• Cons: Can be noisy and more expensive in terms of initial investment and potential maintenance costs.

How to choose the right fan for your grow room

Selecting the right fan for your grow tent involves considering several factors, including the size, the type of plants you're growing, and your budget. Here are some key considerations:

• Size of the grow tent: The size of your tent will determine the type and number of fans you need. Larger tents may require multiple or more powerful inline fans to ensure adequate air circulation.
• Airflow requirements: Airflow is measured in cubic meters per hour (m3Hr). To calculate you need 20 air changes per hour for fresh CO2 in your grow area. If temperature is under control, this is fine. Growers use up to 200 air changes per hour if your grow lights are creating a lot of heat as that removes the air from a grow room quickly (around 30-60 seconds) - use more when in doubt.
• Noise level: Some fans can be pretty noisy, which can be disruptive if your grow tent is in a living space. Use our silenced fans, silencers and acoustic ducting.
• Speed control: Variable speed fans allow you to adjust the power based on your grow tent's needs. This can help conserve energy by adjusting the speed automatically with a controller that increases or decreases based on the set temperature or humidity, reducing noise when full power isn't needed.
• Durability & quality: Investing in a high-quality fan can save you money in the long run. Look for fans with durable materials, reliable motors, and positive customer reviews.
