Imo: yes…
you should at least “worry” enough to do the maths….
Ballpark (assumes rosin takes zero space in the jar):
30g @ 75% THCa (MW 358.5g/mol) would be expected to produce how much CO2?
(0.75 * 30)/ 358.5 =0.0628 mols of CO2.
At STP that’s 0.0628mol * 22.4L/mol =1.4L
Which sure as fuck won’t fit in a 0.188L jar without raising the pressure…
One might even be expect 1.4/0.118 =11.864 bar (~ 170psi) if you managed to keep it all in there
Good thing canning jars are designed to hold vacuum and tend to leak under pressure…usually between 1-3bar. Fortunately the lids also tend to buckle before the jar explodes (most of the time).
Personally I would not tighten that ring down…
