This is another question we get often, but cannot ever provide an exact answer. Basically the term “Garbage in, Garbage out” is a FACT with pressing. Rosin will typically taste
very much like your starting material smells so using the best material available is always recommended. We have seen results as low as 5.5% with low quality material and
have also seen 31%+ with Grade “A” material. Your best bet is to press a couple of .8g nugs to see what you can expect from your material before loading your extraction bags. ANOTHER GREAT TOOL IS THE USE OF OUR TERP FILES with examples and others results worldwide with strain, Yeild%, Temp, Pressure and more.. you will need to setup a free account with an email and you can start loging your results and see all others results to include @NugsmasherOfficial  LINK FOR TERP FILES
