I personally think it's a bit overboard to focus on on the whole "if it's frozen longer than 24 hours all the trich heads will break" blahblahblah speel. I know there are hash/pot snobs out there with their loupes and scopes and shit who say these things...but in the end can the average user discern hash made with trim frozen for more than 24 hours? Maybe it makes a difference in some small way...but I don't buy into the thought that it makes it harsh or ruins the product/etc. I've yet to hear anyone say "Man...was that shit frozen for more than 24 hours before you made this?"
Those folks go without free hash around here. Truth be told...around here we have a freezer full of hash makin' bud all year long and we pull out bags to make a new batch when we need freshies. I personally think freezing it and using it as needed is a better approach than spending weeks at harvesttime making bub as the garden is harvested and then trying to store that hash for the upcoming year.
Obviously...I freeze my hash makings. I use whole plants....just chop that shit up....but not too much. Fill those pound bags up and freeze em. Nice nuggies work very well. Shake makes greener product. Unfrozen trim/etc. often makes hash that is reminiscent of the old blonde brick hash we got in the 70's. More like pressed kief from my experience. Around here...I keep the top tops for the wife but damn near everything else gets squished (a new process here that may replace a large portion of the bubble I make) or chopped and frozen for hash.I even have my own deep freeze...nyuk..nyuk...(you don't want trim in with your food unless you like the taste of ganja) I also use one of those Chinese/plastic washing machines to mix the hash/ice/water. Watch the Frenchy Cannolli vid on youtube where he's on his back deck. I do pretty much what he shows in the vid. Bypassed the drain on the washer and everything. Works very well....
Every strain perfoms differently from my experience. Even the same strain can vary somewhat from batch to batch. Some will give you only one/two bags of full melt...others will just drop that shit in every bag and blow yer mind. I've been through a bunch of different drying approaches. What I've settled on lately is....no pressing.....just drop the chunk/scrape out of the bag onto a silicone mat/etc... and then chop it up with a razor blade like it's 1980 and yer a coke head. Spread it out....let it dry a day or so...then flip it....let it dry...flip it...chop it some more if it isn't still too gooey (some don't chop, the gum shit up) I just keep chopping it smaller and drying it.....takes about 2 weeks. then I jar it into small Mason/jelly jars with silkscreen "lids" so it can breathe.
Some freeze it wet...and "microplane" it....but that's too OCD for me. Keep chopping it on the tray...and it will eventually be somewhat like sand like the snobs want it to be/say it should be.
Some kinda fun.......
