This is the heart of the AutoPot system. One of the most clever uses of mechanical and fluid dynamic principles. What does that mean to you? The valve works independently of electrical power or timers!
How it works:
Through a series of floats, the valve allows you to connect 1/4 inch tubing to it and will automatically fill the container it sits with water to a height of 3-4 inches. It then turns off and waits until the level drops (water used up by the plants) and then further waits momentarily, allowing the potting mixture to slightly dry and air out before repeating the cycle. It doesn’t get any easier or simpler than that. Great Australian engineering at its best!
