The Standard IWS system you all the benefits of flood and drain at an economical price
Flood and drain is a horticultural technique whereby nutrient rich solution is pumped into a container, filled with growing media, and then pumped back out.
The draining process draws air into the media which helps keep the rootzone healthy, promotes vigorous growth and exceptional yields.
IWS flood and drain systems can be used with a variety of media such as coco, 60/40(coco/clay), clay pebbles and some growers use soil but for the best results
We recommend a good quality 60/40 mix such as Gold Label.
The grower has a choice of inner pot to suit the media used.
The Aqua Pot is perfect for use with clay pebbles.
The Culture Pot is ideal for use with 60/40 or coco.
The Punched Pot can be used with any media but is best suited to soil or coco.
