Weezard,
I gotta agree with ya. Even most of the books I read indicate a decay of THC even while it is still being synthesized. Most don't indicate what causes the decay, but it has the ring of truth to it. Even when I cure weed in glass jars I always keep them in a cool dark place for that reason.

A real short story for ya...

Back around '94 or so I came across some beans from Afganastan and grew a few of them in my closet. I was using a 600 watt HPS rig at the time and had the door open to allow some extra cooling while I was changing some window screens. In comes a huge bumble bee that heads directly to my closet and my Afgan hash plants. Well it landed on a 2 1/2 ft top cola and never moved again. It took me days to gather enough courage to approach the plant and it's visitor, but when I touched it the bee had passed on to bee heaven and was preserved with it's wings still folding up to land...

I didn't stand a chance, but I imagine it died with a smile on it's face (if bees could smile).
