What's inside
Chunky PON
Good for: Larger semi-hydro setups and passive hydroponics.
Key benefits:
- Extra airflow. Larger mineral pieces keep oxygen moving around the roots.
- Won't compact or break down. Rinse and reuse it.
- Fertilizer-free and ready to use. You control feeding with your own semi-hydro nutrients.
Ingredients: Zeolite, lava rock, chunky pumice, chunky perlite, charcoal chips and maifanitum (maifan stone).
Classic PON
Good for: Self-watering pots and all passive hydroponic setups.
Key benefits:
- Even wicking. Smaller pieces move water up from the reservoir consistently.
- Won't compact or break down. Rinse and reuse it.
- Fertilizer-free and ready to use. You control feeding with your own semi-hydro nutrients.
Ingredients: Zeolite, lava rock, pumice, perlite, calcined clay and maifanitum (maifan stone).
