Rock Wool Grow Cubes – Professional Transplanting Substrate

No.LL-RWA-02

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.

Description



PLANTING STEPS
① Use the nutrient solution thoroughly. Impregnate the nursery plug, adjust the EC value to 1.5 ~ 2.0 ms/cm, and pH value adjustment to around 5.5.
②  Put the seeds into the seedling Plug top, and use small grains of vermiculite to cover.
③ Regulate the temperature, humidity, and light to make the seeds emerge evenly and grow consistently.
④ When the seedling roots grow out of the bottom end of the plug, the plug is transferred into the growth block thoroughly saturated with nutrient solution.
⑤According to the plant variety type, the spacing between the growth blocks and rows should be set reasonably to cultivate strong seedlings.
⑥ When the roots of the plant have grown to the bottom of the growth block, move the growth block to the planting strip (try to use large seedlings for planting).
⑦ Open the upper end of the long strip, inject pH5 right Yingyang solution, soaking for 24  hours, and then open the bottom opening of one end of the planting strip to discharge the nutrient solution.
⑧ Transplant the growth blocks to the planting strips, giving the plants the water and nutrients they need.
