Following Growor’s Cultivation Standard, even after starting on the 3rd week of the flowering stage, the entire growth cycle was reduced by 12 days . The plants’ full THC genetic potential was achieved at 21% , while the plant dry weight increased by 4 grams, leading to a higher quality harvest with significant aromatic increases.

Following Growor’s Cultivation Standard , the entire growth duration was shortened by 2.5 weeks with a plant growth of 3cm / day during the vegetative period. The plants’ full THC genetic potential was achieved at 21% , while the plant dry weight increased by 30 grams, leading to a higher quality harvest with significant aromatic increases.
