Factors For Maximizing CBD and THC Concentrations

When I posted about the decarboxylation process, I wanted to answer a question here about THCA and CBDA. THCA has the fastest rate of the decarboxylation process. It is almost double that of CBDA\’s rate, and this occurs at some temperatures, with an even faster rate at higher temperatures. This rate is dependent upon the concentration of the cannabinoid which undergoes this heating process.

Over a period of time, oxygen and high temperatures lead to the decomposition of the cannabinoid THC and CBD. This happens at temperatures over 100°C, and the THC content is then lower when the cannabinol forms. It is an indicator of a weaker concentration of THC. The recommended conditions for the decarboxylation process to maximize the THC or CBD levels are at lower temperatures, 90°C or lower, and a longer amount of time, of about 12 hours. In contrast to this idea, THCA was converted to a maximum amount of THC at a higher temperature, of 160°C, and in a short period of time, of only under 7 minutes.

The amount of plant material to be decarboxylated is also a factor, since more cannabis plant material slowed down the conversion rate. In order to keep the THC and CBD at maximum levels, even at higher temperatures, heating the plants with no oxygen present, is utilized.
