I've been lurking this thread the past few weeks while I get my rosin press together. Finally got it yesterday and have run a couple test runs on just flower rosin. I'm as green as it gets with pressing, so any tips or pointers to good sources of info on pressing flower or dry ice hash are appreciated!
In the meantime, here's the first details. My first press was with Double Grape. It came out darker than I'd expected, so I tried some Georgia Pie I'd bought at the Medical Market a few weeks back. Also darker than I'd expected, but both tasted very nice. The Double Grape was pungent and musky/fruity and the Georgia Pie was sweet and pungent. I forgot to measure the output of course, but yield seemed OK. Probably 10-15 good dabs worth.
Tonight, I broke out my 61%, 2 week cured Creme de la Chem. I heard back when harvesting that a short cure to 60-62% and straight into the freezer is great for flower rosin, and indeed it was. I vac sealed the 2 oz harvest in 14g vacuum bags (vacuum barely pulled) and into the deep freezer they went. I took 2 grams out from that bag tonight, sticky as fuck in a great way, and then they got stuck in the pre-press. Another good sign. I ended up putting in 2.15 g and got .46 back, a 21.3% return, and blonde as can be at 180 for 2 min. I collected a small amount more at 200 for 2 min, maybe .1 g, and slightly darker. Not bad!
Next is to get some dry ice and those bubble buckets. I have some small 1 gallon bubble bags and some aluminum pollen screens from ebay, but it seems like those bubble buckets are the way to go, and I can try the pollen screens after the fact on the b+ grade stuff if needed, possibly.
Does anyone have experience with using screens like this for post-processing? Or any tips on ideal flower rosin extraction? Cheers! And apologies for the crappy macro quality.
