Collection: Fans & Controllers
Shop hydroponic fans and controllers at A-Grade Hydroponics — inline fans, exhaust fans and environmental controllers for consistent grow room airflow.
Reliable ventilation is one of the most important parts of any indoor grow. Without enough airflow, heat and humidity build up quickly, slowing growth and increasing the risk of mould, mildew and pest problems. Hydroponic fans and controllers work together to keep grow rooms and grow tents supplied with fresh air, removing stale air and helping maintain stable temperature and humidity throughout the growing cycle.
Our fans and controllers range covers everything from centrifugal exhaust fans and inline duct fans through to manual and automatic environmental controllers, giving you the tools to build a ventilation system suited to a small home tent or a larger production room.
What's in this Collection?
Centrifugal exhaust fans for high-pressure air extraction
Inline duct fans for quieter in-line ventilation and intake support
Environmental fan speed controllers that adjust airflow automatically based on temperature and humidity
Manual fan speed controllers for straightforward, budget-friendly airflow adjustment
Digital thermostat and humidistat controllers for precise climate targets
Whether you're setting up your first grow tent exhaust system or upgrading a commercial grow room, matching fan size (CFM) to room volume and pairing it with the right controller — from a simple speed dial to a fully automated environmental controller — is the key to steady, healthy airflow.
Hydroponic Fans & Controllers | A-Grade Hydroponics
Shop hydroponic fans and controllers at A-Grade Hydroponics — inline fans, exhaust fans and environmental controllers for consistent grow room airflow.
Hydroponic fans and controllers manage airflow, temperature and humidity inside grow rooms and grow tents. Whether you're running a small home tent or a full-scale production room, our range covers inline centrifugal exhaust fans, environmental fan speed controllers and thermostat-driven ventilation systems built to keep air moving and plants healthy.
Poor airflow leads to stagnant air, heat build-up and humidity swings — all of which slow growth and increase the risk of mould, mildew and pest problems. A properly sized exhaust fan paired with a reliable fan speed controller keeps temperature and humidity within the ideal range for your plants' growth stage, improving yield, reducing disease pressure and giving you tighter control over your grow environment.

How to choose
Fan size and airflow (CFM)
Calculate your grow space's volume and aim to exchange the air every 1–3 minutes. Undersized fans struggle to manage heat and humidity, while oversized fans can waste energy and dry plants out too fast.
Manual vs automatic control
A manual fan speed controller is the simplest way to dial in airflow — ideal if you're just starting out. Experienced growers often prefer an environmental controller that automatically adjusts fan speed from live temperature and humidity readings.
Ducting and filter compatibility
Match your fan's outlet diameter — commonly 100mm, 150mm or 200mm — to your ducting and carbon filter size to maintain proper airflow and pressure through the whole system.
