Influence of the different treatments tested in planta under controlled conditions (A) and in the field (B, C, D). A Comparison between the proportion of observed traits in Cannabis seedlings of the different treatments and the control under controlled conditions. Differences between treated and control Cannabis plants grown under field conditions on their B shoot fresh weight upon harvesting (n = 30 per group) and on their C heights and D stalk diameter at four different time points until the conclusion of the trial, whereas error bars represent the confidence interval of 95%. Significant differences are indicated as follows: * as P ≤ 0.05, ** as P ≤ 0.01, *** as P ≤ 0.001, and **** as P ≤ 0.0001
