Rockwool is a natural mineral product, made from melted basalt rock, a rockwool product. 
Rockwool propagation blocks are designed for both seed and cutting propagation, for initial plant production prior to transplanting into larger growing blocks, with no root disturbance.

Planting Seeds: Insert 1/2 seeds in the hole on the top of the rockwool cube. Use a toothpick or other similar object to press the seeds down to the bottom of the hole.
