I haven't seen many posts about it, but I grew three of the Blueberry XL regs a few months ago. They turned out pretty well -- not as terpy as some other blueberry strains I've grown, but the buzz is quite nice. I got one male and two females. Both of the females grew a few pollen sacks (one immediately after topping, the other around day 60 and possibly due to mild light stress), but once those were removed there weren't any others. I made about 75 more seeds by pollinating lower branches, plus a couple crosses.
