Deliver water and nutrients exactly where your plants need it most - the roots. The Intelligent Watering Systems (IWS) Flood and Drain System is specifically designed for serious growers, whether you are running a commercial outfit or are a professional grower looking after a larger garden. These systems are easy to set up and use the most of every inch of space, maximising efficiency and reducing waste. The powerful pump forces water and nutrients up through your growing medium and straight to the roots of each plant in sequence, eliminating stale oxygen and refreshing the growing environment. This reduces the chance of pests and diseases developing, as well as maximising yield and productivity. Why settle for less? The Pro System is a larger one with a faster flood and drain cycle to increase effectiveness, yet is fully controllable so you decide how much time your plants spend with their roots bathed in nutrients.
