What's funny is, the second gram I pressed last night didn't squeeze out jack shit. It was a different strain of flower than the first press in the image above.
I even broke up the puck and added a bit more, bringing the weight up to about 1.2, and it didn't blow out. Just produced a rock-solid puck that produced no rosin.
Funny, that particular second strain vapes just fine (it's not particularly weak or anything). It is what it is, I guess.
In my trials it never worked to repress a puck if the first press did not yield. You can still vape or extract them with a solvent or cook with them.
It probably has been said by
@Nattybushdoctor and others already..
What sometimes helped if nothing came out, was to just heat the slug33 some more and wait until it start to flow. The rosin gets a bit darker like that, but better than nothing.
Weight is crucial. In my case loading 1 gram. 1 gram of leaves does not behave like 1 gram of trimmed flower or stems. If I got more blowouts i tried to reduce weight, if no yield tried to increase weight.
Humidity is important. Bone dry weed does not work good. Too humid and the dab sizzles because of the water in it. You can let dry too humid rosin.
Sometimes it was good to press the last 2-4mm very fast. I had less blowouts like that with that weed.
It does not work with one gram of standard black hash. The hash just blew out, as could be expected. But I had to try. Maybe for hash you should load less than 1 gram or put a screen somehow. Smelled the same after the process as before. (Sidenote: Also smelled the same as in the last century)
