The Rock Wool Grow Cube features a pre-drilled hole on the top, precisely matched to the dimensions of Dondwutianzi propagation plugs. This allows for seamless manual or automated transplanting. Because the plugs and blocks share the same material properties, they integrate perfectly, promoting rapid root penetration with zero transplant shock.
With their uniform dimensions and stable structure, these blocks ensure easy handling and root protection during transport. They are the ideal choice for standardized, large-scale commercial seedling production.
Our cubes are designed with precision sizing to fit perfectly into larger Liluan growing blocks or Grodan-compatible systems, ensuring zero-stress transplanting.
*Available in various sizes for seedlings and slabs
