A fine mesh screen from the Bubble Bag system repurposed as a filter for Rosin Tech pressing. By wrapping hash or flower in a 25-micron screen before pressing, the rosin passes through while plant matter and contaminants are retained inside, producing cleaner rosin.
// From the Episode
Bubbleman credits Jeff Church for the 25-micron screen technique. He notes this is especially useful for pressing flower (bud), where plant matter contamination is a bigger issue. The screen allows rosin to leak out cleanly while keeping debris contained. Jeff Church demonstrates wrapping three-star hash in the screen, pressing at 230 degrees for under 30 seconds. Bubbleman predicts these screens are 'about to get popular.'
