Yeah ive tried both fresh and dry and fresh frozen and dry frozen and theres really no difference. its all about how long you shake it.
Essentially the wet is better because it takes longer to freeze the plant material so the trics break off first and the plant later.
But if you shake long enough it really doesnt matter. unless you did like 1 minute runs then collected, but thatd be pointless haha.
Im lucky enough to have a gas store with all types of gases for welding and cooking and heating so they carry a bunch of dry ice.
And its already in pellet form so i dont have to bother breaking it up.
Ill be trimming soon too. Id recommend you get one of those aluminum turkey trays and sit on your couch.
We always loved trimming at our huge glass table but hated being hunched over the table for hours.
So grab a tray, set up another for finished buds, and sit on your couch and watch some tv or movies. haha.
You can get cheap ass .00 scales on ebay or amazon for about 10 bucks.
Id recommend this one because its stealth but still has a fat surface area for weighing or putting a bowl on it to weigh bigger amounts.
