I remember once someone saying the fastest way to lose a friend is to criticize his trimming, drying and curing technique.
PERSONALLY, I believe that a slow dry and slow cure (a two-month process in general) yields beautiful bud that smokes like a dream, with no harshness or coughing. I grow only for personal use, and I do it so I have access to the highest quality bud possible, grown without sprays, pests or mold. And after four months of growing it's exhausting thinking that there's another TWO months to go with the bud just lying around or in jars. But the end results are spectacular.
Yes, if you don't dry and cure properly, your bud will smell like hay, and once you've missed the dry/cure window there's nothing you can do to get it back. To me this would mean I've grown poor-quality weed, which is not my intention, despite all the effort and quality control I've put into the grow.
The first time I went through this process, I read a lot of classic marijuana cultivation books, like the Cannabis Grow Bible, and augmented that with information here from A Perfect Cure Every Time. PERSONALLY I believe success in this process comes from the slowest dry possible without attracting mold. That time will differ, depending on the region's natural humidity levels, etc. I shoot for 10 days, but anything over 7 is acceptable in my book. In order to do this, I keep the plant as whole as possible and hang upside down, and give a good trim. I want to make sure there's plenty of air circulation around the bud. I keep the humidity in my hanging space at around 55%, with fans creating good air movement. Sometimes I'm using a humidifier, and sometimes I'm using a dehumidifier. Each day I check, first weighing the bud in my hand and touching the outside of a bud to see it's drying out and then bending a stem. Bit by bit I can tell by feel and weight that the bud is changing slowly. After 10 days, I'm done with hanging and starting cutting it up. I do a closer manicure, really getting into the bud and snipping out the leaves. I'm pretty meticulous about this -- you can barely see any leaves in my bud at all. I save all the sugar trim and dry that separately much more quickly, and use that for vaping and brownies.
So that's my process. About two months after harvest, and the bud is ready to be smoked. It will continue to improve even more over time. I've found that if I keep the bud curing in jars at 58% RH for six months, the smoke is amazing and impressive to everyone who is lucky enough to get some from me.
