The pressure needed to extract Rosin from your starting material will vary depending on the following factors: Surface Area, Freshness, Heat Applied, Amount of Material over
the surface area, Type of Material (Cured Flowers, Dry Sift, Bubble, etc). As a general guideline, the more heat you apply, the less pressure you will need (to a certain extent).
From our experience, many strains will press very nicely at around 1000 – 1500 psi per inch of material being pressed in the lower temp range of 190 – 215 degrees.
