Main highlights

Improves the condition of the plants - the use of Keramsit together with soil causes the soil to become looser for the plants, which involves improving the breathing of the roots.
Watering system under control: the creation of a drainage layer of Keramsite on the bottom of the flower pot allows the drainage of too much water and protects the plant from flooding and rot.
The coarse fraction - Keramsit 10 - 20 mm - is particularly useful for drainage in flower pots with large openings in the bottom through which finer fractions could fall through.
Makes it difficult to grow weeds and mould - a top layer of Keramsit in the flower pot inhibits the growth of weeds and rot processes and protects the plants from mould formation.
Ideal for glass compositions - a drainage layer of Keramsite in compositions of plants in the glass allows the maintenance of a correct moisture circulation.

Main highlights

mgc24 Expanded clay is produced by heating high-quality clay minerals. The unfertilised clay granules are odourless, chemically neutral and are not decomposed by soil organisms.
The mgc24 expanded clay granules are ideal as plant granules and have optimal drainage properties. The fine-pored expanded clay balls with their porous core ensure an ideal air and water balance for your plants, indoor plants, flowers, cacti, succulents etc.
The granules can also be used to cover the pot surface to reduce evaporation and thus the watering water consumption. The expanded clay can also be used for admixture when planting larger trees and shrubs in heavy soil.
The colour may vary from the picture due to production.
The coarse structure of the mineral clay balls provides hydroponic plants an optimal hold, stores nutrients and thus creates optimal conditions for vigorous growth. The expanded clay granules are also good for use as a drainage layer when planting containers such as plant pots, tubs, bowls, balcony boxes etc. as the weight of the expanded clay is low.
Grain: 8/16 mm, contents: expanded clay, 20 litres
