I don't agree at all. If that were the case, if you have multiple strains. Each strain woiuld chnage the flavor of the next. I have companion crops in my grow. My last round I had peppermint , lavender, rosemary all chilling in the flower room. Not one of them changed the flavor.
WHAT ARE TERPENES AND TERPENOIDS?
Terpenes appear naturally and abundantly in humans, plants and animals, often to deter parasites. Similarly to flavonoids, terpenes also emit a strong smell and flavor. Terpenes are volatile molecules that evaporate easily and contribute to the aroma of the buds. Research has discovered that terpenes are psychoactive and contribute to the overall effect of a strain. They show a wide range of effects, including sedation, anti-anxiety, anti-inflammatory, and many more. Perhaps surprisingly, up to 30% of cannabis smoke is composed of terpenes and terpenoids.
The difference between terpenes and terpenoids is that terpenes are simple hydrocarbons, while terpenoids consist of additional functional groups. In nature, simple hydrocarbons like terpenes are often the building blocks for larger and more complex molecules, such as steroids, pigments and vitamins. In cannabis, terpenes and THC share a biochemical precursor, geranyl pyrophosphate, which is developed in the resin glands of the plant and then evolves into the cannabinoids and terpenes.
Just like many other strong-smelling flowers and plants, cannabis develops those terpenes to attract beneficial insects and to repel predators.
Many factors, including the climate, weather, maturity level of the plant, the used fertilizers, the soil type the plant grows in and even the time of day have influence on a plant’s development of terpenes.
The great variety of aromas in cannabis strains is already impressive, but the most fascinating property of terpenes is their ability to interact with the other active compounds in the plant. Terpenes can modify how much THC passes through the blood-brain barrier. But their influence reaches even as far as to regulate neurotransmitters like dopamine and serotonin, altering their rate of production and decomposition, their movement and availability to receptors.
