One Smart valve can easily provide water for tray sizes 4m² and larger by water head adjustment up to 1m. The valves work indoors, outdoors and under lights in grow tents and greenhouses, providing a natural 'wet and dry' cycle for your plants with the depth being adjustable to fill between 7mm and 20mm at the turn of a dial.
The Smart valve is for use with any peat, organic based compost or hydroponic media with good capillary lift and can be used with mains water supplies even in hard water areas. It works perfectly with water soluble liquid nutrients, fungicides and pesticides and connects to both 4mm and 6mm (internal diameter) tubing.
Smart Valve watering systems have many potential applications in the fields of hydroponics, landscape irrigation, commercial growing, and household applications to name a few.
