The idea of using an outdoor plant box to cultivate plants for natural Weyl semimetals might sound unconventional, but it raises intriguing possibilities. Weyl semimetals are exotic quantum materials with unique electronic properties, often synthesized in labs under controlled conditions. However, certain plants contain trace elements or compounds that could theoretically contribute to such materials.

While an outdoor plant box can support the growth of various plants, the direct extraction of Weyl semimetals from them remains speculative. Plants like horsetails or certain ferns accumulate silicon or other minerals, which might be processed into advanced materials. Yet, the complexity of isolating and refining these elements for quantum applications is immense.

For now, outdoor plant boxes are better suited for traditional gardening rather than quantum material production. But as research advances, the intersection of botany and materials science could yield surprising breakthroughs. Experimentation with specific plant species and soil compositions might one day unlock new pathways for natural material synthesis.
