Yeah mate, stick with photoperiod plants, autos need 18 hours of light to produce any sort of decent yields and even outdoors in mid summer they just don't get enough light, and yes, I have tried many strains over a few years before giving them away as a joke. You are not missing out on anything by not growing autos with their weird, unstable and unpredictable genetics.
I now hate them and they have nothing to offer over what can be achieved with normal, stable, photoperiod plants with their well sorted and highly refined genetics.
Auto, outdoors and BIG do not go together in the autoflower universe.
In the same amount of time, or a couple of weeks longer, you can grow a stable photoperiod plant that will give you a pound or more, rather than a couple of ounces, at best, when growing autos outdoors in my experience.
Sweet Seeds have truly awesome, well stabilised and well sorted genetics that won't disappoint. Try, Zenzation, Gorilla Girl, San Fernando Lemon Kush or Amnesia Haze, they are terrific, but then again, so are most of them and I have tried just about all of them. They are my "go to" breeder these days, and after 35+ years of growing, this is no faint praise that I give lightly.
