Wonderful BPOM up there Rose. Congratulations!
I too, as BBP said also, have never found a purple I really liked (to smoke). My plants purple up more due to the cold weather than genetics. The GDP in general is a green plant, not purple. I have grown just the one that actually purpled up due to cold outside.
The GDP that I have left is almost two years old and it is as strong or stronger than when it was fresh. I think the flavor has mellowed some tho. I agree with Mutt, put some away and try it in a year.
I get you on the quick dry thing, it has taken me four years to get my drying down to what it should be. I actually don't let my bud get too dry on the screens (not to stem snapping anymore, just time them instead, start checking at five days). I put them in bags then folding down the top of the bag. I open the bags every day to check them. From there I get the "stem snap" feel. Lately I am not leaving the buds on the big stems as I am not hanging many anymore. The Bag also helps to tighten up the buds too. Then they go to Jars or Plastic Gallon Food/Freezer Storage Zip Locks. With Burping daily for a week or so. Burping lasts about twenty minutes, getting shorter as the buds get more evenly dry. If the bud is too moist at the burping stage, I put it back into bags. I was finally happy with my drying technique last year. My trick was not to let the buds go too long on the screens and dry out too much there. Hopefully, I will be able to replicate the process this year.
Mutt...I saw a guy in a car yesterday, he had the word MUTT in the back window. I almost waved. He had a Humboldt license plate.
