What the Eight Screens in These 5 Gallon Bubble Bags Do
The set runs 220, 190, 160, 120, 90, 73, 45 and 25 micron. Those numbers are the aperture of the screen, not the size of what you want to keep. The 220 sits at the top as the work bag and holds the material itself while the agitation happens. Below it the 190 and 160 catch the coarser plant matter that breaks off during a run. The middle of the stack, roughly 120 down to 73, is where most people find the grade they were after. The 45 and the 25 keep catching, but what lands there comes with a higher proportion of fine contamination alongside it. Running the full eight lets you keep those fractions separate rather than blending them by accident. The construction is the other half of the argument. These are built entirely from mesh, so water leaves through the whole surface of the bag rather than through a panel in the bottom. A stack that drains fast is a stack that spends less time soaking. Every seam is double stitched with heavy nylon thread, which is the part that fails first on lesser bags.
Working a Stack, and Why Ice Water Extraction Rewards Speed
Cold and quick is the whole method. The colder the water, the more brittle the resin heads are and the more cleanly they break away from the plant material. Time works against you in the other direction. Material sitting in water leaches chlorophyll, and that shows up as a green tint and a grassy taste in what you collect. Fast draining bags matter for that reason and not for convenience. Nest the stack largest aperture at the top and smallest at the bottom before any water goes in. Pull each bag out in turn and let it drain before you touch what is inside it. Rinse the mesh the moment you have finished with it. Resin that dries into a screen is far harder to shift than resin rinsed out while it is still wet, and a scrubbed screen distorts. Hang them to dry fully before they go back in a cupboard, since a damp bag folded away will grow mould in the seams. The five gallon body is the bench scale in this range. A twenty gallon version of the same eight screen set is stocked alongside it.
