PERLITE
Expanded perlite is a mineral that has undergone a process of expansion at high temperatures. It has valuable agronomic qualities, such as the ability to retain water and fertilisers, improve soil aeration, loosen the substrate, facilitate drainage, stimulate rooting and vigorous plant growth. It can be used in substrate mixes, recirculated hydroponics and lost solution growing systems. Perlite is useful in hydroponics when mixed with coco coir in a specific ratio. A pH in the range of 6.5-7 should be maintained for optimal use. In summary, perlite is a versatile and beneficial mineral component for improving growing conditions and is used in a variety of agronomic applications.
