hey those fast bud are pretty fruity. i grew out 3 late last season and managed to cross with a (non autoflowering, unfortunately) short rider male. I managed to get one of the few bad batches of short rider that nirvana shipped out. The yields were pretty poor because of some frost right during their bulking up period, but they smelled pungently of flintstone vitamins and over ripe fruit. good luck! they definitely were strong growers, and so are the f1s.
