Description
A special, soilless substrate is required for the Bonsanto Hydrosystem. Our expanded clay, which has been specially developed for the Bonsanto Hydrosystem, is low in lime and offers the advantage of storing water for up to 24 hours while maintaining high air permeability. This is crucial for healthy root development.
The expanded clay is supplied in 4-litre units, which is exactly enough for two runs in the Bonsanto Hydrosystem or for two separate Bonsanto Hydrosystems.
Scope of delivery:
- 2 x 4 litres of low-lime expanded clay as a soilless substrate
- Suitable for two cultivation cycles in the Bonsanto hydro system
