Grodan Rockwool Mini-Blocks Wrapped 2″x 2″x 1.5″ 24 Pack


Good for seedlings and cuttings


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.
