Hydro Flow's Ebb & Flow Outlet Extension pairs with any of their Ebb & Flow outlets and their Ebb & Flow screen. These extension fittings allow you to adjust the fill depth for your grow trays by raising the screen and increase the amount of water required to fill the tray before it drains. They slide in and out with ease for simple adjustment during your grow.
