Rosin Technique....Easy DIY Solventless

I'm all about getting the most out of my material, so I'll certainly vape it after I extract it. Is it even worth doing if I'm going to be using a hair straightener? I've never actually tried concentrates, and I kind of like the idea of taking fewer tokes to reach the same level of uplift.

Remember with everything cannabis-related, the better you put in the better it comes out. This definitely applies to rosin. Good buds with good technique will yield very terpy solventless oil. So terpy, in fact, that despite living in California and having access to reputable brand name BHO and CO2 oil, I've dabbed 90% rosin for the last year or so, since I started experimenting and getting some sort of tiny results. It's fantastic, the dabs taste AMAZING if you do it low temp and with a carb cap. I find myself using a little less rosin to achieve equal or better results compared to BHO too. CO2 in general is weaker I've found, just the deal with using supercritical CO2. I just love rosin. Flower rosin, kief rosin, hash rosin, bubble hash rosin, scissor hash rosin! All of it!!

If you want to get all of it out, then you can grind the rosin chips and vaporize them. Taste is subpar but you'll get a few hits out of it. I wonder how much of it is cannabinoids and how much of it is chlorophyll etc. Depending on how well the extraction is done on the particular chip, I may get more than a few hits and I might get a buzz off of it. I use hair straightener plates with an arbor press and a small pipe extension on the handle for a little more pressure with less effort. Set to temperature (preference 240-250) and put the goods in and press down for a bit. I'm pretty good at getting the majority of what I want out on the first press so second presses tend to come out green and sappier as that oil is being exposed to two separate heating cycles and very likely that second press oil is more decarbed than the first press. We've seen what some of those lab results show regarding the amounts of activated cannabinoids in rosin being higher than BHO, sometimes up to 2-2.5x higher, although also seeing results where rosin is 2-3x higher in terpene content than BHO. It would make sense that the second press would have more activated cannabinoids and be sappier (I've noticed that "normal" unactivated hash oil can be very shattery to sappy, but activated oil is ALWAYS and ONLY ever sappy). I'd recommend grinding the rosin chips hot off the press if you can.

When I first started it was just the iron and body weight. Then I got a clamp. Then a better clamp. And then the arbor press. With each upgrade, my yields got a little better and I was able to drop my temperatures a little more. Don't get me wrong, you can definitely get dabbable material and good stuff at that without spending any money on it, but you'll be getting consistent and better results with a setup where you can replicate pressure and keep it consistent. Plus materials are surprisingly cheap (hell, you can get a good hair iron from Goodwill or a similar thrift shop for less than $5 usually) and you're only risking burning yourself a bit if you're not paying attention.... better than blowing yourself up and lighting the house on fire if you're not paying attention...

Picture related, a recent flower press of some King's Kush. That's a little bit of the ~0.8 grams I got from pressing 4 grams of flower (22% return).

Thank you so much for the very in depth and instructional reply! I look forward to trying it out once my firefly 2 finally comes.

Picked up a press and had a chance to do a couple test presses.

3.5g of 2nd tumble OG Kush sift ended up yielding 1.5g of rosin.

Which press is that?

I have a similar 1 ton arbor press, but those plates look simple and great.
 
Nintenjoo,

Yeah, well, that's just, like, your opinion, man.
PSA: The arbor press that company used is the $40 harbor freight harbor press that has been painted/powder coated and marked up to $125.

A few members have broken this model.

Think it was ~$80 markup, but fair points. Probably cheaper to just buy their plates (or others) and do it yourself...and might be better to have a beefier press.

The convenience of making one purchase and it coming to my door pretty much ready to roll out of the box was a factor for me, as I find myself a bit low on time these days.

how is it for pressing flowers?

Haven't had a chance yet myself, but hoping to soon...this video makes it looks pretty decent for the task though.

Cheers

not arguing against your points at all but maybe since it is based on a mass produced arbor press (even if it is not the best one) replacing only the press itself if it broke would be easy (for the relatively lazy presser)?

Good to see you back 2clicker. Can you tell us how the press you shared with us earlier is holding up. Were the nuts or bolts you used strong enough for 5 tons?

glad to be back. the nuts and threaded rod hold up just fine. the top and bottom plates may be a tad thin as i do get some bending there. no worries yet though as the plates are still flush with each other. it doesnt bend much but i can see it.

i should add that i dont have a way to measure the pressure im applying. i just pump until i cant anymore. i doubt its the full load considering its a small device. hard to say really.

i still have not pressed any bubble. want to but just dont have accesss to 3 or 4 star.

I'd really like to see someone with a gauge find out if pressing with bottle jacks as much as we can is anywhere near the pressure the jack claims. I'm doing the same thing as you, and a lot of us here are too, it would be good to know.

And this is a good test to see the pressure you're putting out. Throw the jack under a truck and see if it's hard or not to raise off the ground. My jack lifts a medium size truck easily, like it isn't even there, so in the press when i'm cranking down on it i know there's at least half a trucks weight pressing on my pucks. I don't have anything heavier to test, but you probably get the idea.
