I hung up a few branches and after five days it already seemed to be at that stem breaking point. My buds are pretty loose. I personally wanted to avoid things being too dry.Everything was living tissue, with plant cells composed of a good amount of proteins (composed of amino acids), DNA/RNA, chlorophyll, and other substances containing some nitrogen (N) atoms. I can't think of any N-containing substance that would desirable be in cannabis, including smell and taste not being right. Terpenes and cannabinoids generally contain no N. The smell is from final breakdown of N-containing substances to NH3 (ammonia), most likely from microbial fermentation or enzymes within or released from dead cells.
Getting this smell (N-compound breakdown) early while drying is what you want, while the internal tissues still have enough water to support some microbial and enzymatic activity. Otherwise, if dried too fast, I'd presume that more of the N-containing substances will remain longer.
I often let plants (or branches) dry for 10 days for more. I see no need to rush the drying process, such as do it in less than 5-7 days.
What you posted makes sense. But do you end up over drying in any instances then?
Sounds like some odd smells are common at first, then it should dissipate and turn into that Dank smell?!?
