Thanks Aridbud, I'll try the spray mixture.
I was hoping Super blueberry haze was a true auto. Breeder description doesn't specify that it’s a super auto like annapurna, chaze muay thai etc, even though it has super in the name.. Specifies that it grows to 80-130 cm tall.
Super autos probably won't do well in my climate at 60N, as they will take too long, is my guess.
Aren't all flash super autos just semi auto, like you said? Photo crossed once with an auto, or worked to auto and then backcrossed to photo? Thus maybe reducing flower time, but still heterozugous for auto gene, and therefore photoperiod in reality? Probably too slow for my climate, this one.
Still I will let it go for as long as possible. Even pollinating it with a smaller male growing next to it, so I get new regular seeds to work further.
