Expanded clay aggregate

Drainage that does not rot, develop mould or wear out for years. BIOVITA Agro Gardening Expanded Clay is a lightweight ceramic aggregate fired at high temperatures – hard, porous granules with a particle size of 8–16 mm. Spread across the bottom of a pot, it drains excess water and protects roots from rotting; mixed with soil, it loosens and aerates it. Approved for use in organic farming.At a glance Capacity: 4 l Type: expanded clay – lightweight ceramic aggregate (expanded, fired clay) Particle size: 8–16 mm Composition: 100% expanded clay, no additives Intended use: potted and ornamental plants, vegetables, trees and shrubs, lawns Application: 2–5 cm drainage layer at the bottom of a pot, 10–30% soil amendment, mulch, hydroponics Coverage: 4 l provides drainage for approx. 6–8 pots measuring 15–20 cm or 2–3 larger planters Certificate: approved for use in organic farming What makes this product stand outExpanded clay is made from clay fired at temperatures above 1000°C – the granules expand, forming a hard shell and porous interior. As a result, they are lightweight, do not crumble, decompose or alter the pH of the growing medium, while water flows freely between them. This is the simplest way to ensure effective drainage in pots without holes or with decorative cachepots, where water collecting at the bottom most often leads to root rot.BIOVITA’s Agro version is expanded clay approved for use in organic farming, with a clean, uniform 8–16 mm particle size – coarse enough not to clog drainage holes, yet fine enough to be used as a soil amendment. The convenient 4 l package is a home-sized portion: enough for several repottings, topping up a cachepot or mulching a few pots.How to use it step by stepPreparation: Before first use, rinse the expanded clay with water in a sieve to remove dust from transport. No soaking or other treatment is required – it is ready to use immediately.Drainage in a pot: Pour a 2–3 cm layer into the bottom of a pot or planter (4–5 cm in large planters). In containers without drainage holes, increase the layer and water more sparingly. You can place a piece of horticultural fleece over the expanded clay to prevent the soil from mixing with the drainage layer, then add the growing medium and plant.Soil amendment: For plants that require free-draining soil (succulents, cacti, monsteras, citrus plants and Mediterranean plants), mix expanded clay with the growing medium at a ratio of approx. 1:5–1:3, or 10–30% by volume. In the ground – when planting trees and shrubs – add it to the planting hole in heavy, clay soils.Mulching and watering: A 1–2 cm layer of expanded clay on the surface of a pot reduces evaporation, algae growth and fungus gnats. Expanded clay does not replace watering – water your plants as usual, checking the moisture of the soil rather than the drainage layer.ApplicationsExpanded clay is an essential drainage material for pots and planters for indoor, balcony and patio plants, a soil-loosening amendment for succulents, cacti, citrus plants and aroids, as well as a growing medium for hydroponics and cultivation in cachepots with self-watering inserts. In the garden, it is useful when planting trees and shrubs in heavy soil, as decorative mulch and when establishing lawns on poorly drained sites. The manufacturer also recommends it for planting trees in urban areas.Gardener’s tipPlanting in a decorative cachepot without drainage holes? Pour 3–4 cm of expanded clay into the bottom and place the nursery pot on top, making sure it does not stand in water. Excess water after watering will drain into the aggregate, slowly evaporate from there and increase the humidity around the leaves – exactly what calatheas, ferns and other tropical plants like. Every few weeks, pour out any water remaining at the bottom.Specifications Product BIOVITA 4L Gardening Expanded Clay Capacity 4 l Form loose aggregate (ceramic granules) Composition / Particle size 100% expanded clay, particle size 8–16 mm Intended use drainage, growing-medium component, mulch, hydroponics; potted plants, vegetables, trees and shrubs, lawns Coverage drainage for approx. 6–8 pots measuring 15–20 cm Certificate approved for use in organic farming Packaging bag Manufacturer BIOVITA Sp. z o.o.

A drainage bag for the entire garden and all planters. Agro horticultural expanded clay is a lightweight ceramic aggregate fired at high temperature: hard, porous balls with a particle size of 8–16 mm that do not break down, rot, or alter soil pH. 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 package is enough for drainage in several dozen pots or beneath a flower bed and hedge. Approved for organic farming.At a glance Capacity: 45 l Particle size: 8–16 mm Type: lightweight ceramic aggregate (fired clay), BIO product Composition: 100% expanded clay, no additives Intended use: vegetables, ornamental plants, lawns, trees and shrubs, hydroponics, green roofs Applications: drainage layer, substrate component, mulch, planting trees and shrubs Coverage: 45 l provides a 4–5 cm drainage layer over approx. 1 m² or drainage for approx. 40–60 20 cm pots Certification: approved for use in organic farming What makes this product stand outExpanded clay is made from clay that expands and sinters into balls in a rotary kiln at temperatures above 1000°C, forming a hard shell and porous interior. The result is a material as light as cork yet as durable as ceramic: it does not become completely waterlogged, crumble under the weight of soil, decompose, or freeze into a solid mass. Moisture stored in the pores is released slowly, helping expanded clay stabilize moisture levels both in pots and in flower beds.The 8–16 mm particle size is the most versatile: large enough to create a permeable drainage layer without passing through drainage holes, yet fine enough to look attractive as mulch. The 45 l bag from BIOVITA is far more economical than small packages – an excellent choice for repotting an entire collection, creating flower beds, planting trees, and green roofs.How to use it step by stepPreparation: 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.Drainage in pots and planters: 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, mix some into the backfill soil as well.Substrate component: add expanded clay at approx. 10–20% of the volume to heavy garden or potting soil and mix it in. The substrate will become lighter, better aerated, and less likely to compact into a crust. In green roof substrates and beneath lawns on clay soil, expanded clay serves as a drainage layer.Mulch: spread a 2–4 cm layer of expanded clay around potted plants and on flower beds. It reduces 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.ApplicationsAgro expanded clay 8–16 mm is primarily used for drainage in pots and planters – for houseplants, citrus trees, aroids, and succulents – as well as for drainage beneath trees, shrubs, and flower beds in heavy, clay soils. It works well as a substrate component for vegetables and ornamental plants, as mineral mulch in pots and flower beds, as a medium in hydroponics and bottom-watering systems, and, according to the manufacturer, for planting trees in urban areas, on lawns, and in green roof technology. It is reusable – after rinsing, you can use it again.Gardener's tipInstead of conventional drainage at the bottom of the pot, try “reverse” watering: place the pots on a tray filled with expanded clay and pour water directly onto the balls. As the water evaporates, it increases the humidity around the leaves, while the roots do not come into contact with standing water – a simple way to keep calatheas, ferns, and orchids happy in a dry, heated home.Specifications Product Agro horticultural expanded clay Capacity 45 l Form loose aggregate (ceramic balls) Particle size 8–16 mm Composition 100% expanded clay (fired clay) Intended use drainage, substrate component, mulch, hydroponics, planting trees and shrubs, green roofs Coverage 4–5 cm layer over approx. 1 m² or drainage for approx. 40–60 20 cm pots Organic farming approved for use in organic farming Packaging 45 l plastic bag Manufacturer BIOVITA Sp. z o.o.
