Soil Amendment Vermiculite
Vermiculite is a hydrated magnesium aluminum silicate mineral commonly used as a soil amendment in cannabis cultivation. When heated to high temperatures, vermiculite expands into a lightweight, porous material that improves water retention and aeration in growing media. Breeders and cultivators incorporate vermiculite into substrate blends to enhance nutrient availability and create favorable conditions for root development. The mineral's cation exchange capacity allows it to hold nutrients and release them gradually to developing plants. Vermiculite is often combined with perlite, peat, or coco coir to balance moisture and drainage characteristics in custom growing formulations.

Breeders working with specific phenotypes may select vermiculite-amended substrates during controlled trials to standardize growth conditions and ensure consistent expression of genetic traits across generations. Proper substrate composition supports reliable phenotypic evaluation when comparing cultivar lineages.
