I currently grow both of these. Mine are the clone only phenos available only through friends of friends. I don't know about the BX2, but we do grow the real deal Pre-98 Bubba. We also have Tahoe OG clone only, and Tahoe OG x Chemdog. The Bubba will outyield the Tahoe by a longshot. Both root in 7 days. The Tahoe is the real deal OG. It's a small, low yielding plant that produces world class buds. It's all about quality with that girl. Grow her with high density numbers for best yields.
The Bubba yields more, but is not in quite as high demand. It does have a loyal following and represents 90% of what we grow for production.
