VERMICULITE MEDIA

VERMICULITE MEDIA with a grain size of 1 - 6 mm for agricultural use VERMICULITE MEDIA is a mineral belonging to the mica family.‎ It is a product of natural origin that undergoes an irreversible high-temperature heat treatment and is expanded, losing its combined water by vaporisation and becoming extremely light (95 +/- 20 kg/m3) and insulating.‎ After the expansion process, the vermiculite is sieved to obtain a product with a fine grain size of between 1 and 6 mm, characterised by a neutral to slightly alkaline pH.‎ Thanks to its lamellar structure, VERMICULITE has a high water storage capacity, is an excellent drainer, and also guarantees good exchange and accumulation of nutrients.‎ Being a porous material and an excellent thermal insulator, it also protects root systems from thermal changes and guarantees their oxygenation, keeping the temperature of nutrient solutions constant.‎ Given its nature, it is also rot-proof, sterile, chemically inert and free of pathogens, maintaining its characteristics and performance over time.‎ Loose mineral aggregate.‎
