IWS grow systems: flood and drain, dripper and autodrain
IWS builds modular recirculating systems that grow by adding pots to the same controller rather than by replacing the whole setup, which is why they turn up in rooms running anything from four plants to forty. Everything works off a control unit and a reservoir, so once the plumbing is in, scaling up is a matter of pots and fittings rather than a new system.
The choice between them is really about how water reaches the roots. Flood and Drain, in the Pro Remote 25mm and the bottom-fed Trident, fills the pots from below, holds the level for a set time, then drains back to the tank, pulling fresh air down into the medium on every cycle. The Dripper System feeds from above through emitters instead, giving smaller and more frequent doses that suit coco and finer media. Autodrain combines dripping with a timed drain and covers 4 to 40 plants from one controller.
The IWS Oxypot Vegetative is the deep water culture option if you would rather have roots in solution than in a pot. Spares are listed here too, which is the point of a modular system: grommets, fabric pots, 25mm Pro drain fittings, outer containers, stands, and copper discs for keeping roots out of the drain line. Pair with tanks & reservoirs and air pumps. Call 020 3488 0419 to size a system.
