Composition
A finer, balanced composition for steady moisture
The structure distributes moisture through the root zone, while mineral components prevent dense compaction around fine roots.
- 1.5 parts coco coir: Forms the base and distributes moisture evenly.
- 1 part worm castings: Adds bioactive organic matter and gradual nutrition.
- 1 part perlite: Maintains air channels and supports drainage.
- 1 part vermiculite: Retains water and releases it gradually to the roots.
- Small amount activated carbon: Supports a cleaner root environment.
- Small amount lava gravel: Adds stability and small air spaces.
- Added organic nutrients: Provide built-in nutrition for the initial period.
Even moisture
Coco coir and vermiculite reduce abrupt swings between overly wet and overly dry mix.
Air around fine roots
Perlite and lava gravel maintain air spaces without making the mix excessively coarse.
Gentle bioactive base
Worm castings and organic nutrients support growth for about 180 days.
Repotting steps
For Calathea, Maranta and plants that prefer a steady microclimate
Use it straight from the package in a pot with drainage and keep the mix lightly moist, not saturated.
- Calathea
- Maranta
- Begonia
- Strelitzia
- Musa
- Tropical plants
Support the root system carefully and avoid pulling the fine roots.
Use a pot with drainage holes; plastic or glazed ceramic slows excessive moisture loss.
Add mix around the roots and settle it with light taps, without firm pressure.
After repotting, wet the full mix and allow the excess water to drain.
Steady moisture does not mean standing water
Check the mix regularly and water before it dries out completely, while always allowing excess water to leave the pot.
