Marix Discs are designed to fit the 1Pot system, the easy2grow kit & the 2Pot extension trays to extend the easy2grow kit.
The discs are black and are placed inside the pot; the purpose of the Marix Disc is to prevent compost or soil from leaving the pot, keeping the system clean and the AQUAvalve free from debris.
They will also provide protection from escaping roots, and although the Marix Discs will last several seasons, it is advisable to replace the discs at the beginning of each season; this will prevent any disease from being transferred if present.
