// Definition
A hybrid technique where water-extracted hash is dried, then mechanically sieved through dry sift screens to isolate trichome heads by size. This allows a wide-range water hash catch (e.g., 160-45 micron) to be re-separated into distinct head sizes, producing star-rated grades from a single extraction.
// From the Episode
Johnny B (John) describes his Water Sift technique in Ep 026, where he catches a large range from 160 to 45 micron in bubble bags, vacuum dries the patty, then cards the dried resin through dry sift screens (86, 125, 180, 196, 230 LPI) to re-isolate by trichome head size. He was able to produce six-star, five-star, and four-star grades from a single batch.
