Limestone Tolerance
Limestone tolerance refers to a cannabis plant's ability to thrive in alkaline soil conditions where calcium carbonate (limestone) naturally elevates pH above neutral levels, typically 7.5–8.5 or higher. Plants exhibiting this trait show reduced chlorosis and nutrient lockout symptoms commonly observed in pH-sensitive cultivars grown in such environments. Limestone-tolerant genetics are often traced to landraces and regional populations adapted to calcareous soils in the Mediterranean, Middle East, and parts of Central Asia. Breeders working in limestone-heavy regions have selected for this characteristic across multiple generations, resulting in stabilized lines that maintain vigor without intensive soil amendment. Understanding this classification helps cultivators in high-pH regions identify compatible genetics and informs breeding programs focused on environmental adaptation.

Breeders targeting Mediterranean, Middle Eastern, and chalky-soil regions prioritize limestone tolerance as a stability trait, reducing cultivation inputs while maintaining consistent phenotypes across seasons and locations.
