IWS (Intelligent Watering Systems) is a UK-made brand of modular hydroponic irrigation systems, founded around 2006. Now manufactured and distributed by Global Air Supplies, IWS designs automated, scalable setups that let growers manage many plants from a single reservoir. The range covers Flood & Drain (including the Trident bottom-feed design), Dripper (run-to-waste), and Autodrain systems, with kits commonly scaling from 4 to 48 pots and options for flexible or rigid tanks. Systems are built to a high specification in the UK and are widely stocked across the UK and Europe. IWS focuses on simple installation, precise feed timing, and expandability, making it a popular choice for hobby and commercial indoor cultivation where reliable, repeatable irrigation cycles and efficient nutrient use matter.
