IWS flood & drain 6 pot

IWS manufacture the finest flood and drain watering systems available. This system enables the novice gardener to become an expert overnight. Can be fine tuned to suit precise needs. It utilises mechanical 15 minute timers with fine tuning minute timers for full control of the growing system. The IWS is a highly developed flood and drain system which works by flooding from the bottom of each individual pot. The pots are made of 3 parts: as stand with a preset height and a 5 degree slope which allows all the water to drain back to the main tank stopping the roots from sitting in water; a base pot with a water tight gland through which the nutrient is delivered and a seperate drain pot with machined holes in the base allowing the flood and drain action.
