volcanic raw materials

The Canary Islands are of volcanic origin and are mainly composed of different types of volcanic rocks. The volcanic activity that led to the formation of this archipelago began about 20 million years ago and is still active, as recent eruptions on La Palma show.

Lava is molten rock that rises from the earth's interior to the surface during a volcanic eruption. After it reaches the surface, it cools and solidifies into solid rock.

Lava rock is often used as a planting substrate because it has several beneficial properties. These properties make it particularly suitable for certain types of plants, including cacti, succulents and bonsai, as well as in hydroponic systems. Here are the main properties of lava rock that make it a good planting substrate:

Lava rock has a high porosity, which means it has many small holes and cracks.

This porosity allows for excellent drainage and prevents waterlogging, which can be harmful to many plants.

The pore structure ensures good ventilation of the roots. Lava rock improves air circulation in the substrate, which promotes root growth.

Despite its good drainage properties, lava rock can retain water. This ensures that plants have access to water while at the same time draining away excess water.

Lava rock does not decompose and retains its structure over a long period of time.

It remains stable in the substrate and does not change the physical properties of the soil over time

Lava rock is a naturally occurring material.

It is sustainable and environmentally friendly because it does not contain any synthetic ingredients.

Lava rock is lighter than many other substrates.

This makes handling easier and reduces the overall weight of planters, which is particularly advantageous for roof gardens or balconies.

Lava rock can be added to the soil to improve the structure, especially in heavy clay soils.

It is commonly used in hydroponic systems where it acts as a neutral support for plant roots.

Lava rock offers a versatile and effective solution for planting substrates that optimally support both the physical and chemical needs of plants.
