Grodan Granulate – 50L Box
Grodan Rock-wool is an inert plant substrate.

Being made from natural rock, Grodan is a mineral based product used in hydroponic growing applications.
**Recommended use with Grow House Inc. Nutrients and additives **
Grodan Granulate is water absorbent granules of rock-wool (almost flock like).
This product is extremely practical for using in hanging baskets, as a stand-alone medium or even as a change from traditional potting mixes.
The product is much cleaner to use than potting mixes, has a higher water holding capacity, and can actually reduce watering houseplants to approximately once every 2 to 4 weeks.
Directions for use:
Pre soak in pH 5.5 water/nutrient before use.
