Rockwool Medium
Rockwool medium refers to an inert, fibrous growing substrate derived from basalt rock that has been spun into wool-like strands. In cannabis cultivation, rockwool serves as a soilless medium commonly used for propagation, cloning, and hydroponic systems. The material offers consistent water retention and aeration properties, allowing breeders and cultivators to maintain precise control over nutrient delivery and root environment. Rockwool cubes and slabs are popular in structured breeding programs where environmental variables require standardization. The medium is reusable with proper sterilization, making it relevant to large-scale genetic evaluation and seed production workflows.

Breeders favor rockwool systems for their reproducibility across multiple plant generations and phenotype testing batches. The controlled conditions enable accurate observation of trait expression independent of soil variability, supporting rigorous lineage documentation and parent selection.
