Having won numerous prizes for their smart valve, Autopot has made life easier for countless gardeners and growers around the world. The Autopot Smart-valve ensures that the water drains completely before new water is automatically let back in to a set depth of about 35mm. This allows for maximum use of nutrients from the water, no water wastage, and no need for electricity to control the water distribution. Autopot systems are perfect for use in hydroponic and aquaponics systems.
