I've got a couple autos going outdoors in Florida and they are doing well. One was attacked so I had to re veg and believe it or not it is working. Granted the plant may not grow much more but it has boomed in circumference and height while still growing flower sites.
I've also heard some autos can be ready outdoors in nearly 65 days. I'm told it depends on the strain. Which I know nothing of lol. I'm a first timer but seem to be making very little mistakes.
