If you have tips on how to grow autoflower outdoors....

This is the second time BostonGirl has said what I was getting ready to type. I hope you are in the southern hemisphere or at least the tropics. Auto's need long periods of light for maximum production, like 16-18 hours per day. In the northern hemisphere we are already well past the longest days and they days are getting shorter quickly. So, during flower when the plants really need maximum sun they will be getting less intense sun, for a shorter and shorter amount of time each day. In the future I would germinate your auto seeds about 8 weeks before the summer solstice (longest day of the year). This will allow the plants to be fully into flower during the longest daylight of the year. You can also use supplemental lighting but that could be difficult outside and could attract attention if you live in a non-legal country/state.

Depending on your location it’s a bit late to be starting an outdoor auto. Not that you can’t- it’s just the more sun they get, the more they thrive. Here in New England I wouldn’t have time to harvest before the first frost. Keep them in the sunniest place you can find, and try to keep the buds dry once they start to form. The bud rot has been rampant this year because of the humidity. Best of luck- 🌱
