Cross section, dry bulk density in lb./ft.3 and g/cm3, sphagnum peat moss content (%) and pH for the four experimental substrates.
XValues determined experimentally using an average of three replicates of the saturated paste extract method [21]. WRockwool pH was adjusted before use per the manufacturer’s instruction. YExact values unavailable, percentage was estimated based on company product description. ZValues reported as lb./ft.3 and g/cm3 to satisfy manufacturers specifications and scientific literature, respectively.

Root number (roots; top row), length (cm, center row), and mass (mg; bottom row) for the [A] medium, [B] hormone, and [C] cultivar independent variables for industrial hemp (Cannabis sativa L.) vegetative cuttings. Hormone treatments include Hormidin 1 (H1, 1,000 ppm IBA); Hormidin 2 (H2, 3,000 ppm IBA); 1:10 Dip ‘N Grow (DNG, 1,000 ppm IBA/500 ppm NAA); 1:5 Hormex (Hx, 500 ppm NAA) and an untreated Control. Bars plot represent group means and error bars represent the 95% confidence interval of each group. Connect letter represent Tukey HSD significant difference tests (α = 0.05).

Visual representation of root number (roots; left column), length (cm; center column), and mass (mg; right column) for the [A] medium-by-cultivar interaction and [B] hormone-by-cultivar interaction for industrial hemp (Cannabis sativa L.) vegetative cuttings. Hormone treatments include Hormidin 1 (H1, 1,000 ppm IBA); Hormidin 2 (H2, 3,000 ppm IBA); 1:10 Dip ‘N Grow (DNG, 1,000 ppm IBA/500 ppm NAA); 1:5 Hormex (Hx, 500 ppm NAA) and an untreated Control. Points are independent and lines are being used for visualization purposes.
