hey there Valleywest, truth is you cant trust a breeder's advertised timelines for shit. plenty of different variables go into it, but basically they might not be growing in soil at all when they test them and other environmental conditions that will be different than yours. Overall i would say it's probably just marketting and has no basis in reality. The only thing you can do and should do is to go off the trichomes and that's it. Usually you can expect 8 weeks of flowering on an auto though, sometimes even more. Hope this helps ! 🚀
