I don't understand not getting anything at all from a strain. I even squeeze trim and get a decent amount. Every strain i've ever squished produced pretty decent. I press in the 200 degree range...it's slow, but more terpy and creamy. Posibly your temp was too low to induce a good melt...I dunno. The lower the temp the longer it takes to melt and flow. I have a 20 ton press and it always produces with 90 micron bags filled to the max. Extra empty bag will suckup the rosin......maybe that was it? Not full enough.
