SMS Hybrid 4A Controller
The SMS Hybrid 4A Controller is a premium automatic ventilation controller designed to maintain the perfect growing environment by intelligently controlling both inlet and exhaust fans. Combining advanced software-controlled temperature sensing with reliable mechanical fan speed regulation, the SMS Hybrid Controller continuously adjusts airflow to maintain a stable grow room climate while operating almost silently.
Maintaining consistent temperature and airflow is essential for healthy plant growth. Excessive heat, poor ventilation, and fluctuating environmental conditions can reduce plant performance, increase stress, and lower yields. The SMS Hybrid 4A Controller automatically monitors your grow room temperature and adjusts fan speed as required, ensuring your plants remain in their ideal growing conditions throughout the day and night.
One of the biggest advantages of the SMS Hybrid Controller is its exceptionally quiet operation. Unlike many traditional fan speed controllers that cause extractor fans to buzz or hum at lower speeds, the Hybrid Controller has been specifically engineered to eliminate these unwanted noises. It provides smooth, silent fan control with no buzzing or humming guaranteed, making it one of the quietest climate controllers available.
After selecting your desired grow room temperature and minimum fan speed, the controller automatically increases or decreases fan speed through up to five gradual speed levels (the 2A version operates in two stages). This stepped speed adjustment maintains a stable climate while preventing sudden airflow changes that can stress plants.
The SMS Hybrid 4A Controller also synchronises both inlet and exhaust fans to maintain constant negative air pressure, improving odour control and ensuring carbon filters operate at maximum efficiency.
Installation is quick and simple thanks to its plug-and-play design. No wiring or electrical work is required—simply plug your fans into the controller, position the temperature sensor within your grow room, set your preferred temperature and minimum fan speed, and let the controller manage your ventilation automatically.
Suitable for grow tents, grow rooms, greenhouses, propagation areas, drying rooms, and commercial hydroponic facilities, the SMS Hybrid 4A Controller delivers professional environmental control with minimal effort.

How It Works
The SMS Hybrid 4A Controller constantly monitors the air temperature inside your grow room using its temperature sensor. When temperatures begin to rise above your selected setting, the controller gradually increases the speed of both inlet and exhaust fans. As the room cools, it smoothly returns the fans to your chosen minimum speed. This intelligent system keeps temperatures stable while minimising unnecessary fan noise and energy consumption.
