BIOMAND 18LB Lava Rocks for Plants - Porous 3/8-Inch Volcanic Rock for Drainage, Aeration & pH Balance

BIOMAND 18LB Lava Rocks: premium volcanic stone for plants

Discover carefully sorted 3/8" lava rocks designed for drainage, aeration, and visual appeal. They are pre-washed to minimize dust, though a light rinse is recommended upon receipt to reveal their natural texture and keep your work area tidy.

What makes them special

• Porous volcanic matrix promotes steady water flow and air exchange, helping roots stay oxygenated between watering events.
• Natural minerals may contribute trace nutrients and support stable pH conditions in soil and water environments over time.
• Broad-use versatility: use as a potting amendment for succulents, cacti, orchids, and bonsai; aquarium substrate; or decorative top dressing.
• Durable and reusable: designed to maintain integrity season after season, reducing waste and expanding gardening options.
• Tactile and decorative: adds a natural, modern look to containers and terrariums while supporting healthy root zones.

Where to use them

• Bottom-layer drainage: place a layer at the pot base to promote drainage and prevent water from pooling near roots.
• Soil amendment: mix with potting soil (around a 20% ratio) to improve aeration and structure for moisture-sensitive plants.
• Decorative top dressing: finish planters, terrariums, or displays with a clean, natural surface.

Care, longevity, and practical tips

• Pre-washed to minimize dust; rinse again before first use to keep soil clean during planting or topping.
• Store dry and reuse across seasons to reduce waste and preserve their look and texture.
• Handle with care during repotting to maintain surface texture and avoid excessive dust creation.

Whether you work with succulents, orchids, cacti, or bonsai, BIOMAND lava rocks offer a practical, visually appealing option that complements a range of container setups. They are a potential component of a broader drainage and soil-management approach, rather than a guaranteed outcome, and results will vary with plant type, watering routines, and environmental conditions.
