Horticultural expanded clay granules 8-16mm 60l size: 8-16 mm ensures adequate water drainage helps maintain proper soil moisture prevents mold formation does not change soil pH chemically inert can be used repeatedly supports soil aeration sold in bulk, without multipacking, 1 pc. = 60 liters Expanded clay is a universal material, widely used in gardening and growing potted plants. The granules are used: for drainage, loosening in hygroscopic crops. At the same time, it is harmless to plants and the environment. Expanded clay is a light ceramic aggregate obtained by firing easily swelling clays and clays in rotary kilns at a temperature of 1200°C. It has high thermal insulation, resistance to chemical and atmospheric factors, fungi, insects and rodents. It is an odorless, non-flammable, frost-resistant material with low water absorption. The product is completely chemically inert - it does not change the pH of the soil, it is not soluble or washed out by water. Expanded clay is completely resistant to any activity of pests, mold or fungi, which reduces the risk of infection for plants. Expanded clay is a durable, lightweight, porous and chemically inert material that can be used as a skeletal element of the substrate. The reliability of expanded clay is due to its easy assimilation with plants and the microorganisms that accompany them. The special properties of this material allow it to be used in hydroponic crops and in crops with drip irrigation correlated with fertilization. Expanded clay does not lose its shape, form and consistency, does not rot or deteriorate, which allows it to be sterilized and reused. The granules are used for drainage of pots and containers (m.in. flower beds) with plants and for structural naturalization of the substrate (e.g. sprinkling the surface of the soil in which succulents are grown). Expanded clay can be used in the cultivation of trees and ornamental shrubs and wherever mulching is used to inhibit the growth of weeds
