Right on brother.. I think my main issue is that I have ~40% RH and my buds would dry crisp in 2-3 days max so then I jar them.. it quickly raise up to 70% humidity within hours. I air dry in couple hours crisp again, back to 70% humidity in hours. This would go on for weeks battling hay smell, and over drying the buds. This was buds basically manicured like I would if I am jarring, nice neat you know. Then dry.. but it seemed to dry quickly and then never let any moisture outside unless you cracked the buds when smoking but then its too late or even not started. This did bring out a hint of smell as well other then hayish, as the potency was decent I thought until now. From my first couple of runs, I can see already I wasted years of my crops doing it that trimmed dry way, the hay smell is NEVER there anymore, the smell is almost TOO much, the buds are the consistency and spongy feel I want. Before they were just hard, they looked beautiful but hard and ya they weighed more because of all the water retained maybe thats why many use it, quantity over quality the new American way (yes I am American).
This way it seems to never "trap" the water so the bud can not equalize per say and continue to dry and I think even cure. All I know is that the first couple strains I did with this method over my last method, was 10x better then anything I have produced and that is the only change I did because I wasn't satisfied with my end result (I never am but I am getting close).
