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!

These work really well for starting whatever kind of seed

  • A must have item in hydroponics!
Fantastic product for hydroponics gardens. Even small diy projects are made easy with this product. Simple 4” drain pipe, a series of 2” drilled holes, 1” barbed bulkhead fittings, tubing & small fist tank pump & this product. You're hydrophobic gardening 👍

  • It is Cubes for hydroponics 3/4" cubes
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.

  • Good quality but...
The cubes are good quality but unfortunately, it does hinder root development. I went back to sponge types that allow easier root migration.

  • They grow poorly
Bought these because they were cheaper, and will not buy again. Seedlings take much too long to grow in these blocks. When they do grow, they are weak and spindly and very few of them grow in an upright fashion. I think these blocks are too dense compared to the other brand I used. As others have said, they create a lot of dust when you handle them and they feel a little like fiberglass. There is the main block, which sits upon a wider base made of the same material. This base is tenuous and can easily separate from the main block while handling. The seedlings shown have been growing for weeks now, and there is no sign of roots. Plus the main stems are thin. I have used a quarter of the box over the last months, and given these a fair shot, but it’s a no go. ... show more
