Substrate Amendments
Substrate amendments are additives mixed into growing media to modify physical properties, nutrient availability, or microbial activity. Common amendments include perlite for aeration, vermiculite for water retention, compost for organic matter, and mycorrhizal fungi for root symbiosis. Breeders and cultivators use amendments to tailor growing conditions for specific genotypes, as different cannabis lineages often respond differently to soil composition. Amendments can affect phenotypic expression—root development, nutrient uptake efficiency, and plant structure—making them relevant to understanding how genetics interact with cultivation environment. Proper amendment selection supports consistent expression of target traits across multiple grow cycles.

Breeders document how amendments influence phenotype stability and vigor in breeding stock. Consistent substrate composition helps isolate genetic traits from environmental variables, enabling more reliable selection for desired characteristics in parent lines.
