Beck substrate is inspired by Garrotxa volcanic area in Spain.


Beck substrate is inspired by the volcanic area of Garrotxa in Spain, where natural elements combine to create a stunning landscape. Our Riverbed features a mix of textured stones, bark, twigs, crushed leaves, and shells in subtle shades, all inspired from this unique region. These elements are combined with black volcanic sand and gravel to create a striking contrast of light and dark, perfect for creating a moody ambience or providing a backdrop for bright green plants.

In the words of the Chilean poet Pablo Neruda, "We need to sit on the rim of the well of darkness and fish for the fallen light with patience." This sentiment is reflected in the design of our Beck substrate, where the contrasts of light and dark are used to create beauty and visual appeal. The mix of textures and materials provides endless opportunities for nature artists to express their creativity and imagination.

The combination of textured stones, bark, twigs, and crushed leaves evoke the rugged landscape of Garrotxa, while the subtle shades of shells add a touch of elegance and sophistication. The dark volcanic sand provides a natural backdrop that enhances the visual impact of the substrate. Whether you want to create a moody ambience or contrast with bright green plants, Beck substrate is the perfect choice.
