Autopot Replacement Marix Disc Square - Black

Marix Discs for square 8.5 L and 15 L pots as used in easy2grow, 1Pot, and Auto8 modules. Place one Marix Disc into the bottom of each pot before adding substrates or plants. Marix Discs help to prevent substrates from escaping downwards through the holes in the pot base, keeping your module tray clean and your AQUAvalves fully functional.
