I'm sorry but again that's wrong. This is not a matter of opinion.....this a quote from me on pg 10 iso thread." The ultra-violet rays activate such bonds to form free radicals, which then react further with oxygen in the atmosphere, producing carbonyl groups in the main chain. The exposed surfaces of products may then discolour ,although in bad cases, complete product disintegration can occur.
Polymers which possess UV-absorbing groups such as aromatic rings (thc and other cannabinoids/aromatic terpenes) may also be sensitive to UV degradation. Aramid fibres like Kevlar for example are highly UV sensitive and must be protected from the deleterious effects of sunlight......remember that thc is a phenol ... but its an aromatic mono terpene as well"
The plant produces thc all its life in the same ratio as other cannabinoids all its life. Even in veg and seedling a plant has trichs covering every inch, though they may not be visible to the naked eye (roughly 2% thc in veg). The plant continually metabolizes, recycles and produces until its life cycle is complete. At which point the heads stop producing precursory cannabinoids. Terpenes at this point cyclicize and product is now degrading. Visible by heads turning amber......and actually the sun throws an average of 7k lumens at most about 10. This is equal too 110k roughly in lux. My 600 watt cool tube out performs the sun at closer than 8 inches
