Predicted flowering time is 7-9 weeks. July 13 seed up, outside in a 5-gallon grow bag/1.25 gal. water daily. Flowering began August 10. That puts the C-4 hybrid at around 71/2 weeks. Trichromes tell the story, at least for me ( and so many more ) 40% sativa 60% indica. That's what I'm seeing. To go longer, you'll definitely take her away from the GENETICALLY ALTERED HYBRID, That is 60/40 and feminization, altered. In my experience, a little earlier (?) from the "PERFECT HARVEST" rather than wishful thinking is night and day. But thanks for communicating in the best possible way
