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 50 cubes, 200 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!

    • It is Cubes for hydroponics 3/4" cubes
Size: 200 Plugs
I grow Aeroponically and order a lot of hydroponic supplies. These Cubes are the same as all from China with 3/4" cubes. While the Rockwool does not have to fill the net-pot it would be nice if they came in 1" circles to assist in planting.

    • Rockwool falls apart
Size: 98 Plugs
All of the rock wools arrived fallen apart into small layers of fibers. One might need to use scissor to cut into square and somehow glue it back together into a cube or payer the broken pieces into a net post that it can establish a base. This is the first time we ordered from this brand and sadly it will be the last for its poor quality. ... show more
