Agra-Wool 4x4x4cm - Rock wool cubes - without hole

Characteristics of rock wool cubes

The Agra-Wool rock wool cubes, measuring 4x4x4cm without hole, are designed for seed germination and cutting rooting. Made from basalt, a solidified volcanic rock, these cubes provide a natural and ecological substrate. Moreover, they are more suitable for hydroponic and horticultural cultivation than yellow cubes.

Advantages:

• Natural material: Made of fibers obtained by heating and spinning basalt, these cubes provide a healthy substrate for roots.
  
  
• Ecological binder: Use of Ecose® technology, a natural binder free of acetylates and formaldehyde, making the substrate more accessible to the roots compared to traditional rock wool.
  
• neutral pH: Ensures a stable environment, facilitating the absorption of essential nutrients by plants.
• Adapted dimensions: Each cube of 4x4x4cm without hole offers flexibility for various sizes of seeds and cuttings.

Advantages of hydroponic culture:

• Optimal water retention: The fibrous structure maintains ideal humidity, reducing the frequency of watering.
• Excellent ventilation: The pores of the material guarantee efficient air circulation, preventing the risk of root rot.
• Easy handling: Agra-Wool rock wool is soft, odorless and dust-free, and does not irritate the skin, providing comfort during handling.
  
• Environmentally friendly: The production of Ecose® binder requires 70% less energy than traditional binders, contributing to a reduced ecological footprint.
  

Usage tips :

1. Preparation: Immerse the cubes in a nutrient solution adjusted to a pH of 5.5 to stabilize the substrate before use.
2. Planting: Gently insert the seeds or cuttings into the cube, ensuring good contact with the substrate.
3. Irrigation: Maintain constant humidity without saturating the substrate, ensuring good aeration.
4. Transplantation: Once the roots are well developed, transfer the entire cube to the final culture system.

Precautions:

• Handling: Although Agra-Wool stone wool is soft and non-irritating, it is recommended to wear gloves during prolonged handling.
• Disposal: After use, the cubes can be recycled or reused in the garden or compost, although rock wool is not biodegradable.
