Gro-sure perlite is made from natural volcanic rock heated to high temperatures to produce lightweight micro-porous granules.

Mixing it into compost in place of sand creates a light open structure with good aeration and drainage, while boosting water retention and absorption. Ideal for stimulating strong, healthy root growth.

For best results, we recommend dampening the perlite before use to reduce dust. If using the whole bag, pour up to 1 litre (2 pints) of water into the bag and leave to soak for several minutes before use.

Contains 10 litres.
