IWS (Intelligent Water Systems) builds the automated hydroponic systems that a large share of UK grow rooms are running. The Flood & Drain system is the one most people start with - a reservoir, a set of pots and a Brain control unit that floods and drains on a schedule with no daily input from you. Alongside it sits a full range of dripper, AutoDrain and platform systems, plus the pumps, stands, trays and fittings to build or extend any of them.
Flood & Drain: Complete systems plus the Brain Control Unit and Pro Remote 25mm - see all flood and drain systems.
AutoDrain: AutoDrain stands and components for run-to-waste setups where you do not want to recirculate.
Top Spin dripper kits: 16mm low and high pressure kits, 25mm high pressure, manifolds, stand kits and 12-pack replacement dripper and line sets. Browse irrigation systems.
FloraFlex platform systems: 4, 6, 8 and 9 PotPro platform drainage systems sized for a 4 x 4ft space, plus the complete micro drip and platform drain system.
Alien Rain: Alien RAIN 6 Pot 30L PRO Silver Series and Alien Rain fabric pots - see all Alien Rain systems.
Benching and trays: Wachsen 4ft rolling benches, XTray 8ft x 4ft rolling benches with trays, Idrolab Idro Infinity trays and RTA stands with gland.
Spares and fittings: Replacement drippers, lines, stands and glands - the parts that actually wear out.
Why choose IWS?
Automation you can trust. The Brain control unit is mechanical where it matters and simple where it can be, which is why these systems keep running for years. Every part is available separately, so a failed fitting is a two-pound problem rather than a new system.
IWS FAQs
Flood and drain or dripper? Flood and drain suits clay pebbles and recirculating setups with fewer, larger plants. Drippers suit coco and run-to-waste, and give you finer control over feed frequency.
Do I need the Brain unit? For a flood and drain system, yes - it is what controls the fill and drain cycle. Dripper systems run from a pump and timer instead.
Can I expand an IWS system later? Yes. The systems are modular - add pots, extend the manifold, or move to a larger reservoir without replacing what you have.
