The filter mesh is designed to fit the 1 Pot system, the Easy2grow kit and the 2Pot extension trays to extend the easy2grow kit. The mesh is black in colour and is placed into the container. Its purpose is to prevent compost or soil from leaving the pot, keeping the system clean and the Aquavalve free of debris. It also provides minimal protection against escaping roots.
These meshes usually last for several seasons, but it is advisable to replace them at the start of each season, which will prevent any disease from being transferred if present.
