B1 is a blend of Composted Bark, Clinker, Basalt and Coir Pith. It has been both pH and nutrient balanced. An appropriate control release fertiliser (CRF) should be applied once plants are potted.
The structure of the B1 mix helps to promote strong and vigorous growth. While the Clinker provides good drainage the coir helps to retain moisture, giving plants the best of growing conditions.
B1 is ideal for most plant varieties including exotics and natives and best suited for pot sizes from 100 mm – 450 mm.
Prepared and tested under strict conditions, this product is certified to Australian Standards 3743 for a Premium Grade Potting Mix
