Product detailed description

A reliable base for strong plants

This propagation cube made from premium mineral wool is a professional solution for all growers who require maximum control and success when germinating seeds and rooting cuttings. Thanks to its unique properties, it creates perfect conditions for explosive development of the root system, which is key to the vitality and future yield of plants such as tomatoes, peppers or herbs.

The version without a pre-drilled hole provides absolute flexibility – it is ideal for direct sowing of seeds or for creating a hole precisely tailored to your cuttings.

Key benefits of the growing medium

• Optimal air-to-water ratio: The fibre structure ensures that roots have constant access to oxygen and the necessary moisture, which prevents waterlogging and rot.
• Inert and sterile material: The cube contains no nutrients, pathogens or pests. You therefore have full control over nutrition (EC) and protect young plants from diseases.
• Stable pH: The material only minimally affects the pH of the nutrient solution, which makes it easier to maintain optimal values for nutrient uptake.
• Support for a massive root system: It allows roots to grow through easily and branch abundantly, which is the basis for a strong and healthy plant.
• Universal compatibility: The cubes can be used without problems in all hydroponic and aeroponic systems, as well as for pre-growing seedlings intended for soil or coco substrates.

How to proceed correctly?

Before use, it is essential to prepare the cube correctly. The procedure is simple:

1. Fully immerse the cube in lukewarm water (approx. 25 °C) with the pH adjusted to a value between 4.8 and 6.0 according to the needs of the plants being grown.
2. Allow it to soak fully. Thanks to its high absorption capacity, the pH of the material quickly equalises with the pH of the solution.
3. Then remove the cube and let it drain freely. Never squeeze it, so as not to damage its airy structure.
4. Insert the seed or cutting and place the cube in a propagator or greenhouse.
5. As soon as the roots begin to grow out, it is time to transplant into a larger growing system.

Whether you grow chilli peppers, tomatoes, strawberries, ornamental flowers or fresh herbs, this propagation cube will provide you with a reliable and consistent start. It is ideal for home growers in grow boxes, professional gardeners in greenhouses and hobby growing on the balcony. It can be used for hydroponics, growing in coco, soil and other media.
