Use the IWC Deep Water Culture (DWC) system to grow your plants for increased growth and higher yields. The method involves leaving plant roots submerged in an oxygenated nutrient solution, while a rich supply of bubbles is created around the root zone. The pots are kept separate and work independently from each other, meaning each pot must be maintained individually. The IWS DWC System is a simple and cost-effective route into hydroponics for both novice and experienced gardeners. We carry a wide range of IWS DWC components and spares that are ideal for upgrading or customising your system. From IWS fittings and pipes to system tanks, timers and pumps, you will find everything you need to build your own DIY system here.
