Oh I feel retarded!! Ya the thing about the water ice method is that once the oils/trichomes are cold they will be knocked off the bud or trim,fall thru the screen to be collected,but yes if they are left wet they could get moldy,this is a pretty easy method,in fact the only easier and way quicker method is using dry ice to freeze and shake them off the bud/trim and out of the bucket onto a flat surface..I never claim to know anything but if I can ever help you out ,I'm never to busy for my bruddas or sistas ,just paying it forward cause I still ask for help too..I have done some first run CWE but my buds were not that frosty and didn't give to much return,same with dry ice hash,I still have maybe a lb to play with,but my wappa plants should be done in a few weeks...peace !!!
