The (A – AAAA) rating system was popularized by BC growers in the late 2000’s after as a way to differentiate their higher priced products from the standard greenhouse/outdoor biker weed that was prevalent at the time. In the ensuing decade, demand for high grade marijuana steadily increased, while advances in growing techniques, scale and markets allowed prices to drop significantly whereby most consumers had access to top grade cannabis. However, this led to waves of “over advertised” marijuana, whereby every seller was promoting their product as AAAA. Many sites still do this today, with Windsor being especially bad. The introduction of legalization and lab testing has led some to question the value of the A rating, yet as any true cannabis connoisseur will tell you- its more than just the THC count.
