Product details

How to use it

A proportion of 2 to 5 % in potting compost is suggested to adjust structure, including in combination with worm castings. It can also be used as a mineral top dressing suited to the pot. Rinse and check the particles before reuse.

Despite its mineral content, this component does not replace an appropriate feeding programme. In terrariums, monitor water levels and prevent animals from ingesting it.
