This takes away any guesswork allowing each plant to flourish in optimal growing conditions. The Smart-Valve works by restricting the flow of water (or nutrient) into the tray until it has nearly all fully drained. At this time, the smart valve opens and allows fresh water to fill the tray again. This wet – dry cycle is similar to what occurs in nature with rainfall and the dry periods in between. There is no need for pumps, as each AutoPot system uses a simple gravity feed method, and the range of applications AutoPot can be used in is immense – from a single plant to huge commercial situations. Each system is controlled by a “Smart Valve” which works in three different step
