The Matrix was not designed to be suspended above, but rather directly on top of, or touching the medium. There are two dimensions for each unit, the larger one is the outer diameter. Measure your pot and purchase the Matrix that fits inside of it. You will need a Matrix unit, the same size Matrix Pad (optional), and the correlating Matrix Circulator. Use with Open Flow Bubblers (not the Multi Flow Bubbler) for Maximum Pressure.
In the Matrix System water and nutrients travel into the Circulator, hit the slope of the Matrix and are pushed outward into eight maze sections that have individual holes dripping the water and nutrients onto the Wicking Pad. There are eight slices to the pie, each section is fed the same amount, going through the maze for even distribution. The Matrix pad is a capillary mat used for wicking.
The Matrix is reusable and can sit on top of or fit into your pot, just be sure all surfaces are touching.Place the Matrix Pad on the surface of your plant, the Matrix Unit on top of it, press down, fit the Circulator into the center holes, and connect your 1/4” OD tubing to the Circulator.
The system blocks light and keeps the top of your medium moist for a more even dry down.
