I 'm sorry to bloat our aussie guerrillero thread, I think maybe someone with superpowers could do a cut/paste with this one:
Presumably light degrades THC, direct sunlight would keep active the photosynthesis which creates chlorophyll, responsible of the harshness and grass taste of the cured buds.
Perhaps if you trimmed every single leaf it is not much affected but I guess that as the plant still lives for some time after being chopped (you hang it down so the sap keeps flowing) and keeps degrading the trichomes I think darkness or at least no direct sunlight or shade is needed.
Thanks for the tip, I noticed that once going through that process following a recommendation by @Tinytuttle. What I saw was the black colour of the buds and an ammonia smell when I open the jar, should have followed the fast dry recommendation, but haven’t read it until today.
