Breeder packaging often says seventy days from seed, and in my experience that number should be read as a best case under ideal conditions. Most autoflower seeds I have grown finished somewhere between eighty and one hundred days once you count a slow start and a proper flush. A table of advertised versus reported finishing times for a range of strains is kept at https://turboautoflowerseeds.com, and the gap is bigger on some genetics than others. Plan your tent rotation around the longer figure.
