“Cannabinoid variation score” represents the percentage of inflorescences deviating by more than 15% from the average cannabinoid concentration in the plant.

“Plant variation score” represent the percentage of inflorescences having concentrations similar to the treatment average across all cannabinoids. It is presented for five levels of variation acceptance: 5, 10, 15, 25, and 50% variation from the treatments average.

“BBLB”-removal of leaves and branches from the bottom part of the plant.

Different lowercase letters near the means within a column represent significant differences between treatments for each cannabinoid by Tukey HSD test, α = 0.05.
