I did a garage grow for a senior citizen I was mentoring. She didn't know what genetics to get so I called up a buddy who is the breeder for Green Dragon in Los Angeles. One of the owners was one of the original strain hunters until he died of Cerebral Malaria hunting strains.
The cultivar he gave me was called Old Family Purple. It was a cross of Grand Daddy Purple x Purple Erkle x TK91
Here's what it looked like when she was getting close to harvest...
This is what the garage looked like after we flipped lights....
I know this doesn't help in locating your cultivar but I imagine you want something showy like this right?
