Freezing your dryd bud, makes it much easier to bust up, frozen in a seal a meal and I use a 5lb sledge to mash the bud I. The seal a meal bag.
Don't just toss bud/nugs into your bubble bags, you will lose 40% of your product. You want as much surface area exposed to the cold water as possible. There's resin in the buds as well as on the outside.
Old material will be much darker then fresh most times. If left at room temp, your old material IMO is useless other then for cooking.
We're doing some old material for a little old lady, we stopped after one wash, and didn't even press it, expresso brown, horrible stuff. We tried some more of her stuff and it's way to dark. Gave her back her contractor bag of trim. Was two seasons old.
We're gonna press some of mine from last season tomorrow, same material ran earlier in the year. I'll post pics to compare color. It's now 6months stored from harvest.
