I would never attempt to speak for Cres... But I think what he means is when you cross an AUTO with a PHOTO results being an F1... When you grow out those F1s is where you will see sex in almost 100% of any auto x non auto in the F1 by 30 days. Without having to flip to 12/12... But Cres will correct me if I'm wrong...
IME with the Buckeye Smash 99% of the F1s I grew out showed sex under continuous light of 20 hrs on 4 hrs off under 30 days. BUT to get them to bud up I had to flip them to 12/12... So is this what an "early showing photo" is?? I am also still learning and have tons of homework and questions to ask so please don't take my words as an accurate statement until Cres, Mossy or another Breeder can answer for sure...
Cheers mate... that's egsakly what I was talkin about. Good to hear from someone who's done it. :thumbs:
