R.I.P. Gone, but not forgotten.
Didn't Arthur live in Sri Lanka where the sun is wicked hot and frost never comes? Frost so wrecks the bud us poor Canadians have to get her in a little early to escape the first frost sob sob.
Right from the source, Arthur C. Clarke's Marijuana Botany, Chapter 4, Late Floral Stage. http://www.mellowgold.com/grow/mjbotany-removed/marijuanabotany4.html
The weight yield of floral clusters is usually highest at this point, but strains may begin to grow an excess of leaves in late-stage clusters to catch additional energy from the rapidly diminishing autumn sun. Total resin accumulation is highest at this stage, but the period of maximum resin production has passed. If climatic conditions are harsh, resins and cannabinoids will begin to decompose. As a result, resin yield may appear high even if many of the resin heads are missing or have begun to deteriorate and the overall psychoactivity of the resin has dropped. THC decomposes to CBN in the hot sun and will not remain intact or be replaced after the metabolic processes of the plant have ceased. Since cannabinoids are so sensitive to decomposition by sunlight, the higher psychoactivity of amber resins may be a secondary effect. It may be that the THC is better protected from the sun by amber or opaque resins than by clear resins. Some late maturing strains develop opaque, white resin heads as a result of terpene polymerization and THC decomposition. Opaque resin heads are usually a sign that the floral clusters are over-mature.

LOL, especially when it comes to politics and health care!
