Holiday perlite is an expanded, lightweight volcanic rock used in horticulture to improve soil aeration, drainage, and root development. It acts as an inert, odorless soil conditioner that prevents compaction in potting mixes. Commonly used in potted plants, seed starting, and hydroponics, it provides essential moisture retention while keeping roots breathable.
- Soil Amendment: Mix 10%–40% perlite into potting soil to improve drainage and prevent heavy soil from becoming compacted.
- Seedling/Cutting Mixes: Ideal for promoting easy root penetration in seedlings and cuttings, often combined with peat, coir, or sphagnum moss.
- Hydroponics: Used as a soilless growing medium for maximizing growth.
- Bulb Storage: Used for packing to conserve bulbs and root plants over long periods due to its insulating properties
