Buying Guide
- Material and composition: LECA clay pebbles are lightweight, porous, and reusable. Lava rocks offer natural porosity and mineral content that can aid drainage, but may differ in particle size and dust.
- Size and compatibility: Most products provide 4-16 mm pebbles. Choose a size that fits your pot diameter and root architecture, ensuring adequate air flow without excessive gaps.
- Drainage and aeration: Aim for media with strong porosity to prevent root rot. For hydroponics and terrariums, higher porosity improves oxygen delivery to roots.
- pH impact: 100% natural clay pebbles are typically pH neutral, helping maintain stable root zone conditions. Lava rocks may influence pH minimally depending on composition.
- Storage and reuse: Reusable media offers long-term value. Look for bags that are easy to clean and reseal to prevent contamination or moisture.
- Applications: Use for pot bases, plant pavement, aquariums, and decorative top-dressing. Different media may be better suited for orchids, succulents, or bonsai based on moisture needs.
- Maintenance: Rinse or soak media before first use to remove dust. Periodic cleaning helps preserve performance and reduces potential buildup in hydroponic systems.
