Freezing bud makes it all weird in my experience... Not like bad weird just... I dunno, kinda like mega-ultra-silver-frost-cured or something...
anyway...
i can't answer your question but it intrigues me... I assume this is to extend storage? I think my initial response was the same as Longbottom ^ but now that I think of it, you might be on to something as a desiccant to fight thaw condensation without drying the bud too much.
