What Are IWS Pro Flood & Drain Components & Spares?

Expect high yields and increased growth with the IWS Pro Flood & Drain System. Using a simple tried and tested method, the IWS Pro Flood & Drain System floods plant roots with a rich nutrient solution, and then quickly drains it away. This ensures oxygen reaches the roots, which in turn fuels growth and increases nutrient uptakes and yields. Simple and easy to set up, this system is also automated and wastage is low. This wide range of IWS Pro Flood & Drain Components & Spares allows you to create and keep your fully automated feeding system up and running. IWS systems are completely flexible and allow you to fit your grow-space with a customised layout to meet your needs.
