^ Man, I couldn't tell, wish I had a better grasp on 2nd / 3rd language [I could speak [struggle] Spanish/French, but don't think I could write it! Sorry for the slang, it is even old slang too, not used as much.
18-19% is pretty good, I think I remember the LR being less than 10%, when it was 1st introduced commercially. As far as 39 days, the yield was practically nothing. I would say, even in autoflowers, that good beans are worth the wait of a longer finishing time.
I wish Mandala would make some Auto beans, I would be all over them or MED-MAN. I want some auto Rockstar Kush!
You have peaked my interest, I need to do a little research.....
