Overview

Gerta 10QT Horticultural Perlite Bulk is a lightweight, inert soil amendment designed to transform ordinary mixes into airy, well-draining substrates. The chunky, white grains come from natural volcanic origins, staying open as you water and helping roots settle in without becoming waterlogged. Ideal for indoor plants, seed starting, and raised beds, this perlite lets you tailor moisture and airflow for healthier plant foundations.

Key Benefits

  • Improves drainage and soil aeration, helping roots access oxygen and avoid compacted zones.
  • Supports even moisture distribution, reducing erratic wetting and helping seedling care.
  • Works as a robust rooting medium for cuttings and young plants, promoting even root ball development.
  • Lightweight and easy to blend into pots, containers, and raised beds, making soil conditioning simple.

Ideal Uses

  • Seed starting and seedling care with improved air pockets and moisture balance.
  • Container gardening and houseplants needing steady drainage and root oxygen access.
  • Soil conditioning in compacted soils to enhance overall texture and root health.
  • Mixing with potting soil or soil-less blends for better structure in raised beds.

How to Use

Rinse before use to minimize dust and ensure a clean mix. For most pots, start with a 10–30% perlite blend by volume, adjusting toward better drainage if needed. Use in seed starting mixes to maintain steady moisture and in rooting projects as a light, moist rooting medium.

Tip: When used in combination with other substrates, perlite helps create airflow and water-oxygen exchange, supporting healthier root zones and easy handling for daily care.

What’s in the Box

Each bag contains 10 quarts of perlite, compactly packed in a clear resealable bag for convenient storage. Packaging dimensions are designed for easy handling and transport. Note: Perlite may generate some dust during transit; a quick rinse before mixing is recommended.

Shop with confidence: Gerta offers 1 year of free replacement and 3 months of quality assurance on this product.
