This took 18 1/2 weeks outside. So, it's either a slow auto or a fast photo. Flowering was about 7 weeks so that was spot on. I'm growing another that's at 22 weeks and is about twice this size due to its location being longer full sun in a day. It's a very sticky, not too thirsty girl. I never gave more than 1/2 recommended nutes and that worked okay. Smells amazing.
