What Makes a High-THC Strain?
High-THC strains are bred for top-shelf potency testing at 24%+ THC. THC percentages reflect lab-tested maximum potential under ideal conditions, real-world numbers depend on grow environment, harvest timing, and curing, so expect well-grown phenotypes to land near the top of the range and rushed flower to test lower. High-potency genetics reward experienced growers and higher-tolerance users; if you're new to either, start with a moderate-THC strain before working up.
