Key Uses & Benefits
- Soil Aeration: Its granular structure creates air pockets, ensuring oxygen flow to plant roots and preventing soil compaction.
- Improved Drainage: It helps excess water drain freely, significantly reducing the risk of waterlogging and root rot.
- Propagation: It is ideal for seed germination and rooting cuttings because it provides a sterile, moisture-balanced environment.
- Hydroponics: Used as a standalone growing medium or in soilless mixes due to its neutral pH and excellent capillary action.
- Temperature Insulation: It acts as an insulator, protecting roots from extreme temperature fluctuations.
