Spread across the bottom of a pot or flower bed, they drain excess water; mixed into soil, they loosen and aerate it; and scattered over the surface, they act as decorative mulch. The large 45 l pack is enough for drainage in several dozen pots or beneath a flower bed and hedge.

The result is a material as light as cork yet as durable as ceramic: it does not become waterlogged throughout, crumble under the weight of soil, decompose or freeze into a solid mass. Moisture stored in the pores is released slowly, helping expanded clay stabilise humidity both in pots and in flower beds.\u003c\/p\u003e\u003cp\u003eThe 8–16 mm fraction is the most versatile size: large enough to form a permeable drainage layer without falling through pot holes, yet fine enough to look attractive as mulch. The 45 l BIOVITA bag is far more economical than small packs - it is an ideal choice for repotting an entire collection, creating flower beds, planting trees and installing green roofs.\u003c\/p\u003e\u003ch3 style=\"color: #5C3727; margin-top: 1.5em; margin-bottom: 0.5em;\"\u003eHow to use it step by step\u003c\/h3\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003ePreparation:\u003c\/strong\u003e you can use expanded clay straight from the bag. Before using it in hydroponics or in pots without drainage holes, rinse it with water to remove ceramic dust that could cloud the water and settle on the roots.\u003c\/p\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003eDrainage in pots:\u003c\/strong\u003e spread a 3–5 cm layer of expanded clay over the bottom of the pot (up to approx. 1\/4 of the height in large pots), cover it with substrate and plant as usual. In a pot without a drainage hole, the drainage layer protects the roots from standing in water. In the garden: spread 5–10 cm of expanded clay at the bottom of a hole for a tree or shrub, and in heavy clay soil, also mix it into the backfill soil.\u003c\/p\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003eSubstrate component:\u003c\/strong\u003e add approx. 10–20% expanded clay by volume to heavy garden or potting soil and mix it in. The substrate will become lighter and better aerated and will not compact into a crust. In substrates for green roofs and beneath lawns on clay soil, expanded clay serves as a drainage layer.\u003c\/p\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003eMulch:\u003c\/strong\u003e spread a 2–4 cm layer of expanded clay around potted plants and on flower beds. It limits water evaporation, inhibits weed germination and makes it harder for fungus gnats to lay eggs in moist soil. Water through the mulch layer - expanded clay allows water to pass through freely.\u003c\/p\u003e\u003ch3 style=\"color: #5C3727; margin-top: 1.5em; margin-bottom: 0.5em;\"\u003eApplications\u003c\/h3\u003e\u003cp\u003eAgro expanded clay 8–16 mm is primarily used for \u003cstrong\u003edrainage in pots and planters\u003c\/strong\u003e - for houseplants, citrus plants, aroids and succulents - as well as \u003cstrong\u003edrainage beneath trees, shrubs and flower beds\u003c\/strong\u003e on heavy clay soils.
