There’s no doubt that rosin has tremendously grown in popularity in the recent past. The main reason behind its newfound popularity is the fact that it is a solventless technique. This means that the process doesn’t need the use of foreign substances, unlike other methods that use light hydrocarbons like propane and/or butane which affect the quality of the final yield.

Do you want to produce high-quality rosin or get higher yields? Desire to take your rosin extraction a notch higher and extract pure, potent, and pure resin from your press?

Well, one of the factors that affect the quality of rosin is pressure. A common misconception about extractions including resin is that ‘more is better,’ in terms of pressure. This is untrue. You don’t need an immense rosin press delivered at industrial level PSI to get high-quality rosin. Check out our guide on the best press for rosin and find a press for a good price that gives you the ability to adjust PSI.

Although a larger rosin press gives you more capacity for more rosin with every press, mammoth amounts of squashing power don’t necessarily result in the best resin.

How Much Pressure Is Too Much?

Similar to time and temperature, applying an appropriate amount of pressure can turn out to be tricky. When you apply minimal pressure, it’ll be inadequate to separate the oils. Inadequate pressure makes numerous trichomes remain tied to the source material.

Too much pressure results in what’s known as ”blow out,” where the plant materials leach into the concentrate. Too much pressure results in a higher percentage of lipids and fats in the rosin.

The rule of thumb is, to begin with, low pressure amounts and gradually increase throughout the extraction process until you attain maximum total pressure.

How Much Pressure To Use For A Rosin Press:

Ideally, a rosin press pressure that ranges from 550 – 1500 psi is appropriate for flower resin. Maximum quality occurs at the lower end of this range.

The recommended pressure PSI ranges for a rosin press from 300 – 1000 with less pressure for dry sift and more pressure for flowers.

The three common types of cannabis material to consider are dry sift, flowers, and bubble hash.

  • Appropriate PSI for flower: 600 – 1000 PSI
  • Appropriate PSI for dry kief/sift: 400 – 800 PSI
  • Appropriate PSI for hash: 500 – 1500 PSI

Note: Platen PSI, not the general force/pressure is the important number to focus on. Platen PSI is simply the relationship between the rosin’s bag dimensions and tones of force you apply.

Platen PSI (pressure on source material) = Force exerted by press / Rosin bag surface area

What Factors Impact How Much Pressure To Apply?

We’ve already established that when making rosin, pressure is among the chief factors to consider. When it comes to pressure, different elements affect the pressure necessary to obtain optimal results.

Some of the main ones include:

  • Age of material
  • Cure method
  • Quality of grow
  • Humidity
  • Material type (flower, shake, bubble, etc.)

Final Thoughts On The Optimal Pressure For Your Rosin Press

If your goal is maximum rosin output, you might consider gravitating towards putting more pressure during extraction. Increased pressure helps completely liberate all liquefied rosin within the source material potential translating to more grams on the parchment.

The rule of thumb is to stick to the aforementioned ranges when it comes to pressure for rosin. If you’re looking for more help, check out our guide on how to use a rosin press!
