Basalt

BuildASoil Basalt is a glacial rock dust amendment derived from crushed volcanic basalt. It provides a broad spectrum of slow-release minerals and trace elements to living soil systems, including silica, iron, calcium, and magnesium.

Apply Basalt as a soil amendment when mixing your living soil or as a top dress once per cycle. It improves soil structure, water retention, and microbial diversity, supporting plant health throughout the grow cycle. In cannabis cultivation, silica from basalt enhances stem strength, pest resistance, and heat tolerance.

Basalt is for growers building long-term soil health and using the same medium across multiple runs. It's ideal for those seeking to remineralize their soil and improve overall plant resilience and growth conditions.
