Rockwool
Rockwool Blocks
Plants begin as seeds, and they’re very sensitive at the early stages of growth. To provide cannabis seeds the support they need, try the Rockwool blocks from Shore Grow. These products are made from molten rock spun into fiber, which is then compressed into various forms to suit the grower’s preferences. They have a high capacity to absorb nutrients and retain oxygen that fosters healthy plant growth.
Rockwood propagation cubes are the beginning step. You can transport the seedling from the cube to a larger block or directly into a growing medium.
No matter where the plants end up, what matters is how they start out. Add Rockwool blocks to your collection of growing supplies for incredible results.
