partly ripe buckwheat on frost damaged plants

[Steph S]

Just wondering how much stalk and leaf should be in the cut for buckwheat to ripen after harvest.  I know I saved some last season that weren't fully mature but were cut before frost and whole plants dried - these ripened pretty well.
I didn't really have hopes of a seed crop this year since none were ripe before the time of frost the past couple nights.  But today I'm seeing lots of brown seed or partly brown on about half of the plants.  I just cut and bundled some to hang outdoors where they aren't in the rain, rain expected tonight, the stalks and all are kind of damp as it is, so I was wondering if I stripped them off the plant will they ripen anyway.
If not I guess I'll paper bag the bunches and hang them inside.  Maybe they'll dry some by the end of the day, if we don't have showers.

I haven't grown it yet myself but I know it is indeterminate so it will flower and set seed over time, not all together like wheat/oats/etc. So there is a chance that the earliest seed will be viable, I think.
