Wanted to add a little more to this now that i'm awake...
Cannabinoids weren't necessarily bred out as much as high THC was bred in. For years and years breeders have been practicing selective breeding, most breeders aiming to increase THC levels as well total cannabinoid (resin) levels. The byproduct of this breeding has been extreme total cannabinoid levels but THC has displaced most of the the other cannabinoids. The reason your 43% CBD was a red flag to me is because plants just don't produce that kind of cannabinoid level, that would mean that the plant material was nearly 50% pure resin (trichomes). Even the frostiest, most potent, highest THC or CBD buds are still only in the 25% total cannabinoid ballpark.
Can you please elaborate more on what you mean by producing seed that contains THCa and CBDa?
I was reading this and found it hard to believe they could get results this good ? 99.6 Pure ?
Marijuana contains various cannabinoids, Hornby explains, with THC usually predominant. Hemp has barely a percent or two of THC. The best dried marijuana bud generally maxes out at about 27% THC. Sieved hashish averages about 45% THC. Bubblehash averages about 53% THC. Solvent-extracted products usually have more THC than bud, water hash or sieved hash, but none have tested as high as Budder, and Hornby says Budder is further distinguished because it does not contain any heavy metals, radioactivity, or other markers associated with inferior fertilizers used on source bud.
"The top Budder sample was 99.6% pure," Hornby explained, "which means if you had an ounce of it, only a tiny fraction of a gram would be anything other than cannabinoids. We also tested Budder for toxins, solvents, molds, diseases, heavy metals and other contaminants. There were none. It's essentially just pure cannabinoids. I've tested a lot of cannabis materials, but this is the most impressive."
Hornby's tests also found Budder contains 80 to 90% of its cannabinoids as THC. It contains much smaller percentages of two other cannabinoids: cannabidiol and cannabinol. Of these two, cannabidiol (CBD) is most important because it has medicinal effects and moderates the stimulative effects of THC.
