Rockwool Mini-Blocks are a favorite seed starting medium in the growing industry.

Made from molten rock spun into cotton candy-like fibers, these blocks provide a highly aerated and supportive growing environment for your seedlings and cuttings. 

These Mini-Blocks are individually wrapped in white plastic to minimize algae growth. Remove wrapping and transplant seedlings into any loose media such as Grow-Cubes or coconut fiber or leave wrapping on and set on top of a larger Gro-block.
