Gro1 Extraction Bag Kit (set of 5) - 10 Gallon

The Five Numbers That Define an Extraction Bag Kit

A bag set is defined by its mesh sizes and nothing else, so here they are: 220, 160, 120, 73 and 25 micron. The 220 is the work bag, the one the material goes into so the agitated water passes out through it. Below that the stack grades what came through, coarsest first. The 160 and the 120 catch the larger heads along with most of the plant fragments that made it past the work bag. The 73 is the grade most people are actually after, and it is where a careful run pays off. The 25 collects the smallest heads and the silt, and it is worth keeping separate rather than blending back in. Bags are sized to a ten gallon vessel, so a ten gallon bucket or tub is the working container. The kit weighs about 2.4 lb packed and carries a one year warranty against manufacturer defects.

Working the Micron Screens Without Wrecking Them

Micron screens are consumables that behave like tools, and most of them die from cleaning rather than from use. Keep the water genuinely cold and keep ice in it, because warm water pulls plant matter through the mesh with everything else. Work in short agitation cycles and let the vessel settle before lifting the first bag. Lift slowly and let each bag drain rather than squeezing it, since pressure pushes contaminants through a screen. Never brush or scrape a mesh to clear it, because a stiff brush opens the weave and the bag stops grading accurately. Rinse from the clean side outward with cold water, turn each bag inside out, and hang them until they are properly dry. A damp bag folded into a drawer grows mould in the seams and the seams are what fail first. Label the bags or keep them in order, because 120 and 160 look identical wet. Growers who run the same set every week get seasons out of them. Growers who put them away wet replace the set every few runs.
