I see many voted for rosin.
Does anyone have an opinion regarding the preferred moisture content of the buds? Like should they be very dry, like bone dry, or a nice moist, smokeable dry?
When I did some testing with a hair straightener on 6 different strains, only 2 produced an acceptable result worth going forward.
One of my favorite strains for making oil with ISO, pretty much evaporated, even at low temps. I suppose that is why it is so good for alcohol extractions, I don't know. The iron I have has a temp capability range from 170 to 450F. I used a range between 220 and 310 for my tests.
No big surprise though, there will always be strains that work better with one method over another.
For those with a big press, I have another question: What percentage of yield increase should I expect going from the hair straightener to a press that is 5 to 10 ton? 20%, 40% 80%, etc.?
I will say, the rosin quality was impressive with Strawberry Cough and Querkle. It did not work with my other strains. After pressing, the remaining bud material was still smokeable and not too bad.
I must admit, I may invest in a press, but I will say this, I prefer QWISO, just more difficult to make small amounts.
