I just fold the rosin bags. I do a pre-press with heat. Then let up on the press, fold the rosin bag in half, then slowly let the hammer down. Press to 1 ton for a minute, then to 2 or 3 ton, I listen to hear it sizzle, then really put the power down. Make sure to get all the stem out of your weed. I don’t grind mine. I just break it up really good.
