Had it outside last year. AK47 X ? (can't remember). Finished flowers were very sour smelling and loose, maybe sour D or kin is the other parent. It yields very well. The bud structure wasn't to my liking, but it's exceptional mold resistance was probably a result of the loose structure. Finishes Oct. 20th-25th in N hemisphere so I'd say at least 9-10 weeks inside. Above average potency. Worth a go...
flowers out with the stony girls just fine without lowering light times or other finicky sativa shit to improve production.
I'm not sure what you mean by that. As in lowering light schedule below 12 hours?
I suspect there are a few clones around here being called black betty because mine was light green all the way through until late October. Makes me think the lineage is SourDxAK. Probably just two clones.
