Sterility sets in quick when selfing, sometimes by F2 (though not in this case). Viable pollen from STS is generally the first casualty, followed by unreceptive or difficult to pollinate flowers. It is rare--but not exceedingly so--for the latter to occur. We view pollen sterility as a cry for outcrossing by the plant.
Making more progress on our CBG breeding program. We now have the tools / plants to offer consistent 300:1+ CBG to THC ratio varieties. This material can be concentrated and still be below the federal 0.3% THC threshold. Not bad, right? Results below are from a low-tech QWET (quick wash ethanol) of whole plant material and overnight evaporation on a heated stir plate. The lab (Pixis) is the most precise in Oregon right now. That said, please note that they bungled the total CBG calculation by using a decarboxylation conversion yield of 88.7% (commonly used for THCa-->THC and CBDa-->CBD) when it should be a 53% mass reduction with CBGa-->CBG. (use the latter to see how this plant is actually over 300:1).
