What is Perlite?
Perlite is a volcanic glass material expanded by heat, resulting in lightweight, porous, and sterile particles.
Uses:
- Soil Amendments: Mix with potting soil to improve drainage and aeration.
- Seed Starting: Use as a seed starting medium for optimal germination.
- Propagation: Enhance root development in cuttings and seedlings.
- Hydroponics: Use as a growing medium in hydroponic systems.
- Insulation: Reduce soil temperature fluctuations.
Benefits:
- Improved Drainage: Prevents waterlogging and root rot.
- Increased Aeration: Enhances oxygen availability for healthy roots.
- Water Retention: Holds water, reducing frequency of watering.
- Sterile Medium: Reduces risk of soil-borne diseases.
- Lightweight: Eases handling and shipping.
- pH Neutral: Won’t alter soil pH.
- Increased Root Growth: Promotes healthy root development.
- Better Nutrient Uptake: Facilitates nutrient absorption.
- Reduced Soil Compaction: Prevents soil settling.
- Environmentally Friendly: Non-toxic, reusable, and sustainable.
Ratio for Mixing with Potting Soil:
- General purpose: 10-20% perlite, 80-90% potting soil
- Seed starting: 50-70% perlite, 30-50% potting soil
- Propagation: 70-90% perlite, 10-30% potting soil
Tips and Precautions:
- Wear gloves and mask when handling perlite to avoid dust inhalation.
- Avoid inhaling perlite dust.
- Use in well-ventilated areas.
