Siphon Valve 3/4 inch for Grow Tables

The Siphon Valve drains a grow table on its own using a physical siphon. Once the water on the tray reaches a set point, the valve fires and empties the bed quickly and evenly. No timer is needed for the drain stroke; the rising water level does the work.

Fast, even draining keeps your crops out of standing water, which protects the roots from rot. The drain bore is 17.5mm and it shifts more than 9 litres a minute. The connection is 3/4 inch, 27mm, to suit the standard tray drain point. It is moulded in PP for life with nutrient solutions.
