GAS Enviro Controller v4 26AMP Environment Humidity Temperature AC EC Fan Control

The G.A.S Enviro Controller V4 is an advanced environmental controller designed to fully automate climate management in hydroponics and indoor growing environments. By controlling EC fan speeds and managing temperature and humidity, it helps maintain stable conditions inside a grow tent or grow room, supporting healthy plant development throughout vegetative growth and flowering.

Designed specifically for EC fans, the Enviro Controller V4 automatically adjusts intake and extraction fan speeds to maintain the environmental parameters you set. With an upgraded plug-and-play sensor probe and four programmable sockets, it also allows growers to control heaters, humidifiers, dehumidifiers and lighting equipment from a single unit, simplifying grow room management.

How It Solves Grow Problems

Indoor growers often face unstable temperature and humidity caused by powerful lighting systems and ventilation equipment. Without automated control, these fluctuations can lead to heat build-up, humidity spikes during the flowering stage, or slowed vegetative growth due to inconsistent environmental conditions.

The Enviro Controller V4 constantly monitors grow room conditions and adjusts EC fan speeds to maintain stable airflow and climate levels. By balancing intake and extraction fans, it prevents heat accumulation while removing excess humidity that could affect bud density and plant health.

With programmable sockets for heaters, humidifiers, dehumidifiers and lighting equipment, growers can create a fully automated grow room environment. This stable climate improves nutrient uptake, supports strong root development and helps maximise yield throughout the entire indoor growing cycle.

• 1 × Temperature, Humidity and Light Sensor Probe

How to Use

1. Install the controller in an accessible location within your grow room.

2. Connect compatible EC intake and extraction fans to the controller.

3. Place the sensor probe at canopy height for accurate environmental monitoring.

4. Plug environmental equipment such as heaters, humidifiers, dehumidifiers or lighting timers into the programmable sockets.

5. Configure your day and night temperature and humidity settings using the controller menu.

6. The controller will automatically adjust fan speeds and connected equipment to maintain your chosen environmental conditions.

The controller is designed for use with EC fans only. If using AC fans such as RVK models, a different fan controller will be required.
