How to use
The system floods the pots from the tank on a timed cycle, then lets them drain, pulling fresh air into the roots. Set the cycles at the controls to suit the stage of growth.
Check the feed with a pH and EC meter. For more root space see the Trident 25 litre; spare pots and control parts are in Trident spares.
