Agree 100%.
After reading 4 pages I forgot what the original question is and I'm too lazy to go back and look. So, I'll highlight a bit.
Genetics, RH (end of grow), and light intensity are the largest factors. I've grown trainwreck Arcata cut a few times... always fluffy. God Bud would appear slightly fluffy, but were so dense that a nug would weigh an eighth.
Best cure for me is slow. RH around 45-50, wet trim, and hang in the dark with a little air circulation for a week. Then into the mason jars and burping a few times a day for about a week. I keep a small hygrometer in the jar. After that I burp once a day until I'm around the perfect humidity level. I should note too that I'll usually leave the lids off for 10-15 minutes a this point.
Now, onto boveda packs. Used them the last two grows and they keep the rh in check pretty damn well. But, but, I noticed after pulling out a jar from a grow the summer before last that it tasted better and smelled better. I think this harvest I'm going to skip the boveda packs and compare again. Not knocking the packs. Just an observation.
Now, back to what
@NoWaistedSpace was talking about... I believe modern strains are become more homogenized in general. Difficult for me to articulate on this one, but we don't have a clue yet to all the different cannabinoids and terpene combinations, especially when you consider Plant A from Pakistan vs. Plant B from SE Asia vs. Plant C from Panama or wherever. We're stomping out components to find the strongest Gene's for what we're after whether that be disease resistance, yield, thc levels, etc. and, and, and... you get the picture.
