| Absorbent granulated rockwool increases water holding capacity and aeration, improving plant growth. It can be used alone, mixed with repellent granulate, or used as an amendment to organic based mixes to improve plant growth. When the roots emerge from the rockwool starter cubes it is time to transplant. Put the granulate in a container and saturate it with nutrient solution. If using wrapped starter cube or block, remove the plastic from the block and gently pack the granulate around the block. |
