Blimey...Big Bang from Greenhouse...done in 50 days from seed...I mean they were done, there wasn't anymore blooming....Pineapple Express from Barney's...done in 56 days. Buddha White Dwarf done in 55 days. The info on all the autos I've grown so far all said 7 to 8 weeks from seed to harvest...The longest was Super Critical from Greenhouse. That was 9 weeks. I don't know if it's the climate I live in (I live in the real tropics...only 12 degrees off the Equator), or if it was the genetics themselves, but the plants were fully developed. The smoke was superb...I don't entertain any illusions about yield from an auto...I do what you do...perpetual harvest every three to four weeks. I usually grow 7 to 10 plants at a time...Not sure what it is that you're growing that is still immature at 60 days...
