I picked up a 1/2 oz. of this strain at Eugreen In Eugene, Oregon. I have heard this is a clone-only strain. If you grew this from seed, or bought it somewhere other than the US, it is likely a different version of this strain.
Anyway, Black Betty has a pungent rotten fruit aroma, that is actually pleasant. I say rotten fruit, because it smells like a mix of earth and fruit.
The smoke is a little on the harsh side (makes me cough if I take a full-bowl bong rip), but the taste is top notch.
The stone is a light and energetic one, that is completely absent of anxiety or paronia.
I looked up the genetics, and it says that BB is AK47 x East Coast SD. However, at the dispensary, the say that their black betty is Super Silver Haze x OG Kush. Who knows.
This is one of the best daytime strains I have ever used. It does not stone you down, but provides enough buzz, to let you know it's working.
