Auto variants ... info I found...
Afghan Kush Ryder (auto) ... 45 - 55 days flowering time. But thats flowering time, thats NOT from seed. An auto will generally show signs of switching to flowering mode 10 to 14 days, so thats more like 59 to 69 days from seed. Thats under ideal conditions, theres no guaranteed it won't take another week longer depending on your setup.
Blue Mammoth ... official stats say 70 days from seed.
Vertigo ... official stats claim 60 days from seed. So this ones a possible. But again, it might take a week or so longer than the official stats, setup dependent.
Blue Mystic Auto ... claim 5 weeks (35 days), so thats another option. If thats from seed, if thats flowering time, add 10-14 days to it.
You can't rush nature.
