- High-quality rock wool for cultivation: Made from lava-based rock wool, spun into cotton-like fibres and treated at high temperatures. This results in stable, well-ventilated cultivation cubes that provide ideal conditions for germination and plant growth. The cubes ensure good air circulation and promote healthy root development. - High water absorption and moisture management: The rock wool cubes absorb and retain water while allowing sufficient oxygen access. Good air permeability helps prevent waterlogging and maintains even moisture, ensuring a continuous supply for roots. - Optimal conditions for plant propagation: The unique cube structure gives your plants enough time to develop a strong root system. The sturdy material promotes healthy root formation and supports growth. After rooting, plants can be easily transplanted into soil or other planters. - Flexible cuttable rockwool cubes: The set includes 28 small cubes, each measuring 4 x 4 x 4 cm. These rockwool cubes are ideal for hydroponics and can be easily cut to suit different planting needs, allowing adaptation to various growing projects. - Practical use scenarios: - Seed germination and early growth in hydroponic setups: Use the 4 x 4 x 4 cm cubes to start seeds or clones and transfer once roots are established. - Propagating cuttings to develop a strong root system: Root cuttings in the cubes and transplant to soil or other media after rooting. - Starting seedlings for soil or container growing: Begin in the cubes and move to soil or larger planters when ready.
