[fifty one] Whilst Over-all cannabinoid creation is influenced by environmental things, the THC/CBD ratio is genetically determined and continues to be mounted all through the lifetime of a plant.[36] Non-drug vegetation generate relatively very low levels of THC and substantial levels of CBD, when drug crops develop higher amounts of THC and reduced amounts of CBD. When crops of both of these chemotypes cross-pollinate, the plants in the main filial (F1) era have an intermediate chemotype and produce intermedite amounts of CBD and THC. Feminine crops of this chemotype may perhaps create plenty of THC to become used for drug output.[fifty one][fifty two]
