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.
