My brother did well with Expert Seeds blueberry auto outside in mid Maine last year. Turned into a bush on its own and was tasty/frosty. He had trouble with others using his very basic schedule of ff soil mixed with promix in root pouches outdoors including Flash Seeds Kush Van Stitch, but not this one strain. He had a G13 labs auto that did well but the strain was a one off or something. I looked for it and couldn't find it.
This year, his Flash Seeds Onyx (auto) did the best. I have seen Onyx Reloaded for sale - could be a version two but I haven't read up on it. He tried Dutch passion Think Different outside and it was not a good yield, nor was it very happy with the conditions.
His environment is a cold, somewhat damp one with pine forests surrounding a small field. Cool nights and hot humid mid summer days. It was wet last year there (2014 summer). The blueberry auto liked it.
