Gerta 20QT Horticultural Perlite Bulk

Gerta 20QT Horticultural Perlite Bulk is a lightweight, inert soil amendment designed to improve drainage and aeration for a wide range of plants. The 3-6mm granules feel airy between fingers and reflect their natural volcanic origin with a subtle, glassy sheen.

In practice, many gardeners mix perlite with existing soil to loosen compacted substrates, creating pockets where water can penetrate and roots can anchor. This helps prevent soil compaction and encourages root exploration as plants establish themselves in indoor pots, raised beds, or seedling trays.

Key benefits you can expect

• Improved drainage and airflow around roots, reducing standing moisture.
• Better moisture management for seed starting and cuttings, supporting even germination and early growth.
• Lightweight, easy-to-handle medium that blends with soil and potting mixes.
• Non-toxic, odorless composition suitable for many houseplants and garden beds.
• Simple storage and use: comes in a resealable bag for quick mixing and re-use.
• Quality assurance: 1 year replacement and 3 months QA; note to rinse before use to minimize dust.

How to use

• Seed starting: mix perlite with seed-starting mix to balance moisture and airflow around tiny seeds.
• Rooting and cuttings: use perlite as a moist, well-aerated rooting medium; keep the mixture evenly moist.
• Potting and soil conditioning: blend perlite into potting soil or raised bed mixes to improve drainage and aeration.
• Indoor plant care: place perlite in topsoil to prevent soil from compacting in small containers.

Note: Perlite may release some dust during transport. Rinse or wet the material before use to reduce dust. The product is packed in a 20-quart clear resealable bag, making storage and replenishment simple for ongoing plant care. While results can vary by plant type and conditions, many users report more robust root structure and better soil structure with repeated use. Consider perlite as a flexible ingredient in your soil mix kit—an option for healthier growth and easier watering.
