1. High-quality material - Material and structure: Rockwool is made from high-quality rock wool, spun into fibres. The fibre structure provides 40% higher water retention and a strong ability to absorb nutrient solution. - Safety and environmental impact: Free from heavy metals, it is an inorganic sterile growth medium with no toxic or harmful substances. It is green and environmentally friendly, easy to recycle, and contains 0% chemical residues, making it ideal for organic herb cultivation. 2. Growth turbo - Germination and rooting performance: Optimised pore size (0.5–2 mm) supports 90%+ germination success and 20%+ faster rooting in cuttings compared with standard products. - Plant health benefits: Natural and environmentally friendly material with no root curling, no slow seedling stage, high survival rate, good seedling quality, and strong stress resistance. It stores ample oxygen to promote vigorous plant growth. 3. Professional handling - Product configuration: Includes 28 small precision-cut rock wool cubes, each 4 x 4 x 4 cm, forming a board. - Compatibility and absorption: Designed for tailor-made combinations with aeroponic systems to ensure optimal nutrient absorption and growth efficiency. 4. Sustainable production - Easy setup: Place the nursery block in the seedling rock wool, add sufficient water, and within a minute the block absorbs and expands water to start working. - Versatility and reuse: Rockwool cubes adapt to different culture pot sizes and can be filled according to the gap without cutting. They are recyclable. 5. Practical applications - Aeroponic and hydroponic propagation: Use the 4 x 4 x 4 cm cubes in aeroponic systems to maximize nutrient uptake and growth speed from germination to seedling. - Cuttings propagation: Employ rock wool cubes for rooting cuttings with enhanced rooting efficiency and healthier seedlings. - Organic herb cultivation: Benefit from 0% chemical residues and inert, sterile media suitable for organic herb systems and nursery rows. - Nursery and seedling production: Use as a reliable, scalable growing medium in commercial nurseries to improve germination rates, seedling quality, and stress tolerance.
