Imported substrate-perlite from Holland. Professionally graded and handled to reduce the percentage of fines, this RHP-certified perlite will provide your substrate mix with the structure and aeration that you need.
Perlite is a volcanic glass that is heated to over 800 C° upon which it pops much like popcorn and expands to more than 10 times its size, resulting in an incredibly lightweight material.
Perlite is neither acidic nor alkaline and is particularly useful in plant propagation, including taking cuttings and sowing seeds. While both perlite and vermiculite aid in water retention, perlite is the more porous and tends to allow water to drain much more readily than vermiculite.
Perlite substrate is suitable for both vegetable and cut flower cultivation and creates a reliable foundation for perfect custom-made cultivation control. Use perlite to add air and structure to a substrate mix. Benefits the root development of plants.
