Very sage advice padawan. It is never recommended to freeze any foods more than once, and it seems like a good idea to use that as an example.
I agree @itza419. Now if you were low on bud and you wanted quick a cola or two for smoking, I could understand the rush. Even then I think an oven on warm makes the best quick dry method. My oven is at 135° on warm so won’t do any harm. But just to harvest seeds, I’d wait the 10-14 days.
