what temp are you shooting for during your freeze? i used dry ice last run and i think i may have over froze it, if that's possible? i will say it worked great for prepping the wash solution, but not so much the post wash if that makes sense.
i did some moon rocks with a run and had great results. the nug and kelf removed any trace or hint of that green taste for lack of a better word. as i finished it on a mat i placed my nugs on it and made 'roll ups' then roll in the keef. impress your friends and show em how mayans build shit!!
