The old school layout is a thing of beauty. They are drying down really nicely too, and you have some great bulbs there!
And words of experience, worth remembering.
I'm thinking it's about two weeks to dry down the greens, then trim and 4-5 weeks to cure? Mine probably take a bit longer than that, when I'm doing it all in the basement.
I have a porch that can be warm at harvest time, and I did hang some garlic to dry there one year - the tops dried much faster. Maybe it's okay (or even better?) to have a warm dry down and then a cool cure?
We don't have an optimal climate, tending to be cooler and wetter by the time our garlic is done, but it's good to know what to aim for.
