How much pressure do you need for rosin?
How much pressure does a rosin press need?: It's important to remember that the number to focus on is Platen PSI, not general pressure/force. The general consensus among the industry for full yield capability at lower temperatures is: Flower rosin: 1,200-2,500 Platen PSI Hash rosin: 700-2,000 Platen PSI Any higher Platen PSI will result in unnecessary torn bags, parchment, closing of oil channels, etc. Any lower Platen PSI will result in loss in yields and higher temperatures required for a full extraction. The pressure needed will depend on the temps you use, but, also on what you're pressing. Flower needs more pressure, somewhere between 600-1000 PSI. Dry sift/kief or hash will require less pressure because it is more concentrated. You should shoot for between 300-800 PSI. Too much pressure can lead to a lower quality yield. You can actually end up squeezing plant matter into the rosin, resulting in impurities, poor taste, and overall lower quality. How to calculate Platen PS...
