Ph Sensitivity
pH sensitivity refers to a strain's genetic predisposition to respond noticeably to soil or hydroponic nutrient solution pH levels. Cannabis plants typically thrive in slightly acidic growing media (pH 6.0–7.0 in soil; 5.5–6.5 in hydroponics), but individual cultivars show varying tolerance ranges. Strains classified as pH-sensitive often display visual stress symptoms—chlorosis, nutrient lockout, or growth stunting—when pH drifts beyond their optimal range. Conversely, pH-tolerant cultivars maintain more stable phenotypes across wider pH windows. pH sensitivity is influenced by both genetic background and environmental interaction, making it a useful breeding descriptor for cultivation specialists.

Breeders working with pH-sensitive genetics often prioritize selective cultivation protocols to maintain phenotype consistency in trials. Growers and breeding programs use pH sensitivity classifications to match cultivars to specific growing systems, water chemistry, and nutrient regimens, improving predictability in commercial or research settings.
