Flood + Drain Standard

IWS Flood & Drain Standard is a modular ebb-and-flow hydroponic system built around a central Brain control unit and fixed 15-minute segment timer. Using 16 mm pipework, the Brain floods pots from a FlexiTank reservoir at set times, then drains back, exchanging stale air for oxygen around the root zone. Kits ship with punched inner pots by default, outer pots, pipe and fittings, two submersible pumps and a FlexiTank matched to system size: 100 L (6‑pot), 250 L (12/18/24‑pot) and 400 L (36/48‑pot). Standard pumps are typically rated 1000 L/h for both fill and drain. The design is expandable and suits media like clay pebbles or coco blends. Intended for growers seeking simple, reliable automation without remote controllers.
