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!

  • Not good.
Size: 200 Plugs
Something is strange about these particular cubes. Ive used rockwool for YEARS. Did 15 clones in these. Every. Single. One. Died. Yellow meristem. 0 root development. Used 8ppm water, diluted to 65 with an application of the general purpose fertilizer I use. I adjusted the pH of the water to 5.6. The clones were kept in a humidity dome under 200 ppfd white led lights, (yes I measured it). I do this method with 95% success rate ALL THE TIME. All the clones were given some clonex. Got NOTHING. EVERY SINGLE ONE DIED. Something is wrong with this rockwool. IDK whats in it, but theres something in it. UPDATE: the clones came around at a 90% survival rate, but the pH of the water KEPT SPIKING UP. Had to use more reagents than I would like, or soak them longer than I would like. Very dusty, first rockwool Ive worked with where I felt inclined to wear a mask and gloves. Felt like insulation. Barely usable. ... show more
