Autos do really bad outdoors due to the limited light and generally stay quite small and with correspondingly small yields.
Try growing some fem photoperiod plants with high percentage of indica genes, they tend to finish earlier. Otherwise some breeders, like Sweet Seeds, have "Fast Versions" of many of their normal strains that finish outdoors mid September, well before the weather changes to cold. Other breeders have similar types and are often referred to as "early versions", such as breeders like Delicious Seeds. They are just as potent as the photoperiod plant and have a touch of auto flowering genes, usually less than 1%, which brings on flowering a bit sooner and with faster flower development too. Their yields are far superior to any auto strain when grown outdoors, like 10-50 times as much.
Hope this helps,.........
