here's the actual quote from Ed Rosenthal, "The odor is caused by anaerobic bacteria, which are active in the absence of oxygen. Ammonia is one of their waste products. Anaerobic decomposition quickly destroys chlorophyll, leaving buds tan or brown colored."



Jorge's quote is explaining why mexi-brick is brown and is in his book, but its 300 pages and im not scanning every page to quote mine.



In my experience, when buds are starting out green, a nice cure will lighten that color, producing a light green, that sits behind the white/grey created by the trichomes, with hints of a golden tan/orange highlighted by the pistils/stem/parts of calyx.
