Pokon Expanded Clay Balls / LECA: where it works best
Pokon Expanded Clay Balls are an inert physical medium. They are commonly used for semi-hydroponic growing, reservoir systems and spacing inside decorative pots.
Best use
- Fired clay: durable granules that hold shape
- Semi-hydro use: suitable for reservoir-based setups
- Reusable structure: can be cleaned and reused where appropriate
- No built-in feed: requires nutrient solution for active growing
Prepare before planting
Rinse dust away and pre-soak if your setup requires it. In semi-hydro, keep reservoir height and fertiliser strength matched to the plant and current root adaptation.
Pokon Expanded Clay Balls / LECA in practice
LECA does not remove the need for correct light, nutrient strength, pH awareness and reservoir hygiene. It is a medium, not a guarantee of easier growing.
