Even distribution of nutrients, does not absorb nutrients from the crop, encouraging rapid root growth and higher yield so that suitable for mechanized seedling.
  • 【Easy to Transplant】Rockwool cubes can be cultivated either whole or individually. Since the rock wool is transversely textured, we recommend wearing gloves and cutting with scissors instead of tearing by hand. Rockwool grow cubes keep the seeds long enough to establish a root system because of their high water absorption, so that the survival rate of transplanting is high.
  • 【Wide Application】These rockwool starter plugs have pure composition and handy planting hole, widely used in hydroponic, seed starting, rooting, plant propagation, cloning systems and so on. Low environmental impact, easy to handle compared to other substrates, great for planting enthusiasts and commercial growers.

In the weaving process added a surface hydrophilic effect of binder, can keep the rock wool immersed in water for a long time without deformation, and has a good hydrophilic.
    • Agricultural rock wool adopts the pendulum processing method, the fibers are tight, wavy and interwoven together, the fibers are horizontally distributed, nutrition is evenly distributed, which is conducive to the extension and growth of the root system to ensure the uniform growth of crops.
    • The chemical nature of rock wool is generally alkaline, and agricultural rock wool can adjust the pH value after soaking in acidic nutrient solution.
    • Agricultural rock wool is cut into different sizes when it leaves the factory, and the seedling plug is used for the seedling period, with an eye in the middle, which can be sown directly.
