A reliable foundation for strong plants

This planting cube made of premium mineral wool is the professional solution for all growers who want maximum control and success in seed germination and rooting of cuttings. Thanks to its unique properties, it creates perfect conditions for the explosive development of the root system, which is crucial for the vitality and future yield of plants such as tomatoes, peppers or herbs.

The no pre-drilled hole option provides absolute flexibility - ideal for direct sowing of seeds or for creating a hole exactly tailored to your cuttings.

Key advantages of the growing medium

• Optimum air/water ratio: the fibre structure ensures that the roots have constant access to oxygen and the necessary moisture, preventing waterlogging and rotting.
• Inert and sterile material: the cube contains no nutrients, pathogens or pests. This gives you full control over the nutrition (EC) and protects the young plants from disease.
• Stable pH.
• Promotes a massive root system: Allows roots to easily grow and branch profusely, which is the foundation for a strong and healthy plant.
• Universal compatibility: the cubes can be used seamlessly in all hydroponic and aeroponic systems, as well as for pre-growing seedlings for soil or coconut substrates.

How to proceed correctly?

The key is to prepare the cube correctly before use. The procedure is simple:

1. Fully immerse the cube in lukewarm water (approx. 25 °C) with the pH adjusted to between 4.8 and 6.0, depending on the needs of the plants to be grown.
2. Allow it to soak fully. Due to the high absorption capacity, the pH of the material will quickly align with the pH of the solution.
3. Then remove the cube and leave it to drain freely. Never squeeze it to avoid damaging its airy structure.
4. Insert the seed or cutting and place the cube in a propagator or greenhouse.
5. Once the roots start to grow out, it's time to transplant into a larger growing system.

Wide range of uses

Whether you're growing chillies, tomatoes, strawberries, ornamental flowers or fresh herbs, this planting cube will give you a reliable and consistent start. It's ideal for home growers in grow boxes, professional gardeners in greenhouses and hobby growers on the balcony. It can be used for hydroponics, growing in coconut, soil and other media.
