blueberry is probably the most popular strain for the medical people around here especially if it came from dj short. it's been used as a base for countless hybrids and is well known for its potency and flavor. yield varies according to breeder but generally is known for average yields with lots of trim. potency and flavor are its main advantages. vic high used it for many of his hybrids and if you can find one like, romberry (romulan x bb), space queen (c99 x bb) or ttw (timewarp x bb) you'll really have something and please let me know!
