As many are about to learn, CBG breeding is not as simple as CBD breeding. After discovering our first needle in the haystack in 2016, it took us three full years, tens of thousands of labor hours, thousands of chemical/genomic tests, and 45 acres of field trials to develop our lines. We released White CBG to a small number of farms in 2019 and both White and Stem Cell to all farmers for 2020. Why not Stem Cell CBG in 2019? The answer is critical for farmers to understand and a warning to knock-off artists--it's all about ratios.
There are at least 8 genes responsible for THC production in our CBG varieties. The mother to our White CBG line--named due to its unique, snow-covered appearance and lineage to "The White"--has as many active copies of this gene as a standard CBD variety, giving her a CBG to THC ratio of 27:1. The pollen donor has very few CBCA genes and makes amazing, early flowering hybrids with ratios ranging between 100:1 to 200:1--they are ALWAYS compliant for total THC content.
As any traditionally trained breeder will know, accounting for 8 loci results in a 2^8 (256) possible allele combinations and a Punnet square with 65,536 boxes. This requires literally millions of plants to be grown out and individually tested (specifically for CBCA gene copy number and SNP variations) to create pure breeding stock like ours. Keep that in mind as you see "snowy" sounding CBG varieties without any historical testing documents to verify claims of independent development. F2s of our varieties have unstable flowering times, but can also lead to failed compliance tests. White CBG is great for farmers, but very bad for breeders.
