Wow! How come I never thought of that? Don't tell me. I'm a dumb shit! Lol! So you use 3 bags, with 3 buckets. Except I use the 220, 160,(I have found some decent trikes in this one) and the 73 bags. Wait! Can you elaborate a bit, or show a pic about what you mean by your last sentence? Even though I use a washer with a 220 zipper bag, that may be the way to go. I don't care to use any finer than the 73. They take too long to drain. It's much easier to just siphon off most of the water, and just pour everything that goes thru the 73 into a coffee filter sitting inside one of those wally world filterless coffee filters. Some strains have a lot of smaller trichomes that go thru the 73.
A one gallon set of bags could come in handy when you travel, if the local herb isn't that good, just make some hash.
