Premium quality horticultural clay balls 8-16 mm Horticultural
clay balls are particularly suitable for hydroponic plant cultivation and many other horticultural purposes. Unlike soil, the balls do not compact, so they always remain aerated, cannot rot or mold, and keep the plant roots airy and healthy.
Whether crushed or whole, the granules store water well, so even prolonged absence is not a problem, nor is lack of rain for balcony plants. Water is released slowly, so the material maintains soil moisture for a long time with water seeping through the gaps, and does not dry out quickly even when exposed to sunlight. This makes it suitable as a water storage (and drainage) layer for green roofs.
