Here’s what I started with. Best for small amounts.

If you’re getting into bubbles I recommend this one gallon set. You’ll have all you need at this point to make bubble hash.

I bought some on amazon and was surprised to realize they were the 1 GAL size vs 5 gallon.
Doing ice + water has was sort of a pain with the smaller bags but I like the smaller bags now that I do all dry ice hash.
So if you didn't have access to dry ice I'd go with the 5 gallons bags.
I am not fancy though as its all self consumption so I have just used the 120 bag that last few times for everything and I think it comes out fantastic. Sure there is some plant matter.. but I don't much care.
