G.A.S: The Ventilation and Horticulture Expert

FAQ's

• What types of products does G.A.S specialise in for horticulture?

  Global Air Supplies (G.A.S) specialises in a vast range of products for horticulture, with a strong focus on grow room ventilation and environmental control. This includes their renowned carbon filters, various types of fans (inline, clip-on), air sanitisers, advanced environmental controllers, and full ducting solutions. They also offer products across categories like lighting, nutrients, and propagation essentials.

• What is the difference between an EC fan and a conventional (AC) fan for grow rooms?

  The main difference lies in their motor technology and control. AC (Alternating Current) fans use older technology, are generally less efficient, and when used with basic controllers, can produce a noisy hum or buzz, especially at lower speeds. EC (Electronically Commutated) fans use newer, digital motor technology that converts AC to DC internally. This allows for vastly superior energy efficiency, quieter operation (no hum/buzz at reduced speeds), and precise, linear speed control (0-100%). While EC fans might have a higher initial cost, their energy savings and superior control often make them more cost-effective in the long run.

• What is the G.A.S Day and Night Heater Controller, and how does it work?

  The G.A.S Day and Night Heater Controller is an essential tool for maintaining stable temperatures in your grow space. It features two separate control dials for setting distinct day and night temperature minimums. Equipped with a light sensor and a 4-meter probe, it automatically switches your electric heater (up to 2.5KW/2500W capacity) on or off to ensure your desired minimum temperatures are met around the clock. This allows for precise environmental control, crucial for optimal plant health.

• What is the G.A.S Day and Night Humidity Controller, and why is it beneficial?

  Similar to the heater controller, the G.A.S Day and Night Humidity Controller provides precise management of humidity levels. It features two dials for setting separate daytime and nighttime humidity targets. With its integrated humidity and light sensor, it can control both humidifiers and dehumidifiers (up to 2.5KW/2500W). This allows growers to maintain ideal humidity ranges throughout the entire 24-hour cycle, preventing issues like mould or plant stress, and promoting healthy transpiration.

• What are the general benefits of using EC fans in hydroponic grow rooms?

  EC fans offer numerous benefits for hydroponic grow rooms, leading to better environmental control and operational savings. They are significantly more energy-efficient than traditional AC fans, consuming less power, especially at lower speeds, which reduces running costs. EC fans also provide extremely precise, stepless speed control from 0-100%, allowing for fine-tuning of airflow. Furthermore, they operate much quieter than AC fans, making them ideal for noise-sensitive environments, and generally have a longer lifespan.

• What are the advantages of using the G.A.S SonicAir Humidifier?

  The G.A.S SonicAir Humidifier 10 Litre is a reliable and affordable solution for precise humidity control in small to medium grow rooms. Its large 10-litre tank provides extended operation, minimising refills. It features a maximum output of 800ml per hour, which is fully adjustable, allowing you to fine-tune mist levels. With four multi-directional spouts, it ensures even humidity distribution or can be capped to target specific areas. It also operates quietly (under 35 dB) and includes an automatic shut-down when the water runs empty for safety.
