Features

  • Premium MaterialOur rockwool grow cubes are very effective hydroponics substrates, made of high-quality basalt and chalk, being melted at high temperature then centrifuged at high speed to spraye into 0.005mm fibers and pressed into blocks.
  • Benefits of Soilless CultivationRockwool cubes are superior to other typical hydroponic supplies, with up to 96% porosity and 91% water. 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 TransplantRockwool 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 ApplicationThese 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.
  • Package Included4 sheets of 200 cubes, 50 cubes in total. Simply soak the rockwool cube briefly(10 sec) in acidic nutrient solution and adjust its pH value around to 5.5. Don't squeeze it!
