The AQUAvalve controls the watering system, automatically filling the bottom of the tray to a shallow depth of 20mm, and then switching off the flow from the Header Tank. The nutrient solution in the Autopot Tray then waters the pot from the bottom as the substrate in the pot wicks the solution up. The Smart Valve remains completely shut until all of the nutrient solution in the bottom of the Autopot has been used up. When the bottom of the tray is dry the Smart Valve opens and again allows the Tray to be filled with 20mm of nutrient solution from the Header Tank. The Smart Valve operates as and when necessary, increasing the frequency of the watering as the plants grows larger and thirstier.
A root control disc at the bottom of the 15 Litre pots prevents soil or substrate from falling out of the bottoms.
