I'd like to factor myself out of the ogers kush equation. There are folks here that have a great depth and breath of working the ogers kush.
There are folks like ThaDoctha and all those other folks out there doing amazing work with this plant. The world has access to their good works.
Stash did an amazing job preserving baseline, at least close to it. Guesses on stray pollen would be just a multitude of assumptions.
Ogers Kush truly is a phenom IMHO.
You get amazing smoke in a 60-70 day flower period in contrast to twice or triple that growing sativas. And, on many occasions, ogers kush quality is still hard to beat.
If you find or have an amazing banana OG, send me a cut
