Actually, no I hadn't considered that. I've only done that with my attempts making cartridges, but those always had terps mixed back in.

If I go that route, any reason I wouldn't want to press at higher temps first for max extraction? I'm guessing it's going to end up on the sappy side regardless of starting consistency?

Definitely worth a shot! Here's one from a test press at 250F for a minute or so. Yielded 25%
Still buddering up! Still pretty tasty, not harsh.

Perhaps keep a log of exactly what terpenes are in the varieties that causes you trouble.

Good thinking, I'll give that a shot too, although at this point it's still a matter of discovering the full extent of my allergic symptoms. I know THC is considered an irritant as well so it may be that my best route is with edibles. That said, I have to admit... I really love the effects from dabbing rosin so it'd be a real bummer to give it up. We'll see, I'm going to try some of the ideas recommended here and hopefully I'll see some improvements. A couple weeks ago, I pressed the last 5g of my Peanut Butter Breath that I've been hoarding for about a year and a half, which ended up as some of the smoothest rosin I've personally pressed... but 1.5 year old bud is somehow harder to find. :haw:


This certainly works. Mellows out those sharps terps on rosin from fresh material. Try the jartech on it. It makes the rosin so much smoother on a nail.

Is the basic idea of jartech to decarb while sealed/under pressure?

Ayy, my man! You rock, always willing to jump in and throw caution to the wind! :rockon:

I've got a small jar of rosin on hand that I'll divide and will sample half with a simple decarb, and the other half with jartech (if I can figure out that process). Later this weekend I'll play around with higher temp presses too.

Thanks a ton for all the suggestions, I appreciate all you wonderful humans. :luv:

It's interesting that for the most part, cannabis has traditionally been cured for long amounts of time like that before hashing/ingesting. Cured material is usually smoother to me also. I think everyone is fascinated by terpenes right now, but there's no doubt in my mind that cured canna is going to be as big as cured spirits/wine some day.

I also think processors push "live resin" right now cause it's easy since they are able to skip the dry/cure phase. . . :lol:

Sapphire/ruby insert seems to helps for smoothness too :brow:

The last jar tech I posted was done right on the rosin plates, set the temp to 200-220F and just cook it until it turns transparent and the bubbles dissipate. It will pretty much look like distillate or co2 oil when its done. If you have some of those commercial extract jars with the metal lid they work perfect for a few grams.

That's the main step, The guys doing rosin jam or solventless diamonds heat further on lower heat like 120F for a day or three to promote crystallization.

I still need to try out jar tech. I love the idea of doing the heating directly on the rosin plates, I never thought of that. Great idea @invertedisdead

I have a best value vacs shatter vac with heat mat I am gonna give a low temp shot at, but also wanna try that higher temp like you're running.

Hoping I can get away doing it with 1g run as my preference for dabbing is budder so don't wanna end up with too much jam or syrup in case I find it too to liquidy and difficult to measure dose.

For me I love cured resin more but that's probably because I cant handle the harshness of too much terps, the taste of fresh resin is pretty wicked but I guess ya need to be iron lung.

If you wanna bring the terps alive in your dab, beware this can make you cough like a son of a gun, use a small dab!, but if you do a distilled water soaked qtip swab on your nail, breath in some of the vapor (not all) and leave the can with the vapor in the rig, then take your dab :o :science:

If you prefer budder you might try skipping the high heat phase and just doing a heat cure on your purge mats at 120-140 or so for like 24 hours. Seems the lower heat cures have given me less sappy rosin, more of a sugar-budder type consistency.

I'm sure you're right there... this rosin's nose has turned into something more like root beer :drool: where it had a plain, mild peanut butter flavor when fresh.

I actually just ordered up a SiC insert from fadespace yesterday during their 15% off sale, should be here Thursday. Hoping that makes a difference too but at least it should be easy to clean.

Nice! :rockon: Let us know your thoughts! Been curious of that one.

So, I just wanted to follow up and say that initial tests with decarbing my rosin first have shown a big improvement on my throat/lungs already. Not only that, but it seems to have helped moreso with my insomnia too (which is my main usage).

However, it may have revealed something else about my pressing process... I think I'm using too much pressure, as I'm getting what looks to be a bit of plant material. Going to try lightening up the load a bit next run when I do my test @ 250.

very good to hear superdang,

And i also agree with invertedisdead, curing is very much key for a smooth vape/smoke!

the way i understand it, there is 2 "classes" of terpnes :
mono-terpenes + sesqui-terpene,
most "mono-terpenes" will evaporate during the cure, and the sesqui-terpnes be left behind,
these mono-terpenes is in someway blocking the taste/smell from the sesqui-terpenes at the same time as being the more "harsh" terpenes,

i have experienced this with "live extracts" from fresh plant material, like fresh frozen bubblehash that really made me cough,

again this is just the way i understood it from various videos/forums etc :-)

Second attempt (I used lower temp) to make rosin sauce/jam.

Screwed the cap down over a piece of parchment and set the bottom plate to 110C which kept tge rosin around 45C for an hour, then dropped it to 70C on the plate, 30-35C in the jar, for 24hrs.

So far it is stable like this at room temperature. Overall I lost 0.02g, but my scale is fucky. Maybe be as much as 0.05.

Interesting to hear how it dabs vs the unadultered.

I have a new dabpress press and put it through its paces this weekend. I was curious how much the rosin ended up costing to press.

I am in an MMJ only state with pretty expensive pricing and no home cultivation so that makes it an expensive endeavor from the start. However, I found a significant variance in my results ranging from fairly econmical to cost prohibitive. So far there hasn’t been much rhyme or reason to which flower is going to hit the perfect price/quality balance.

My best result was some “premium” popcorn 25%thc Gorilla Glue that was purchased for $155 for 14g. With squishes averaging around 22% this strain can produce a gram of nice rosin for around $50. I consider this acceptable.

For reference, rosin is almost never on the menu here and the two times I was actually able to purchase any it was $60/g and disappointing quality.

My worst result came from 30%thc Corleone Kush purchased for $58 for 3.5g. For the supposedly high cannabinoid content, the yield was lower than anticipated, especially pressing at 205F for this one. I came out at 11% for the eighth not including a 2nd press not worth keeping. Using these numbers it would cost $149 to produce a gram!

That said, I pressed some Gelato that was also $58/eighth, but it yielded 24% coming to about $70/g. Not cheap, but very nice quality and in the same price range as some of the higher end BHO at the dispensaries here.

Also, fyi, this doesn’t factor in cost savings of reusing the pucks for edibles, so assuming I actually do use them, that will bring my cost down a bit.

Price is secondary to my main goals of nice meds and fun hobby fodder, but it’s certainly more justifiable when the numbers work.

Edit: math

Yeah you never really know what you're gonna get.

Got an overpriced 8th of Sour Blackberry Kush cause it sounded really dank... was supposed to be their absolute best grade of flower... I think it yielded the worst I've ever squished, like 10 or 11%.
They gave me a free 8th of Sunset Sherbet.... 30% 1g return. My best ever... :shrug:

I am convinced that high yielding flower extracts more of the plant cuticle (wax/fats) than others....that perhaps some strains just have more of it.

I say this because like yourself it get tested MMJ and yield is not terribly closely related to just THC content.

Oh, and in all cases my flower has been mason jarred with Boveda for at least some number of weeks prior to pressing...so, its not the moisture content, IMO.

i have experienced low yield from some "bone dry" bud, but after rehydrating yield went up like 8-10%
I am pretty sure that the stream released from the water helps the resin move easier away from the puck during the squish, some of it can really be stuck in here if too dry.

But sure it can also be plant fat.
Sometimes able to judge from how easy it cleans of the banger after a rip,

Do you squish the buds on the same day as purchased?
Or do you let them sit in a jar for a few days with 62% humidity?
This particular herb had a Boveda 58 added to it about 24 hours prior to the press. I am going to buy a hygrometer and some 62% humidity packs to rule out any humidity issues, but the herb didn't feel dried out and actually felt pretty "squishy" prior the press.

I am curious to see some lab analysis of various rosins to see if higher yielding lower cannabinoid herb produces rosin with higher plant matter vs. active material.

Alright, i have in the past tried some squishes at 58, which i think wasnt too far off from the 62,
so it might not be a humidity related problem indeed :-)

And yes that would be very interresting to see,
The best of the best ive seen have indeed come out pretty low yielding.

It was probably fine based on your description but, in my experience, it can take up to a week or more to increase humidity with those packs... even in small increments. I over-dried some homegrown to around 52% this last harvest and it took about 2 weeks to bring it up and stabilize @ 62%.

That's been my experience as well. You never know as there are few consistencies you can find pressing rosin. A few yes, but not many.

In general fresher buds make lighter rosin that butters fast, and well cured buds made darker rosin that seems to be more stable in color and texture. But I've seen plenty of exceptions. And I really can't say if one color or texture is better than another for vaping.

Some of my favorites, super silver haze and Colombian gold have great returns while other favorites, like blue dream, only have so so returns. My worst return has consistently been cannatonic #4, (7-10%) although it has nice dense buds. Another favorite, gorilla glue #4 has nice returns but stays oily. And naturally top buds seem more productive than bottom buds

There must be variables that we don't know about yet that are responsible, something besides temp and humidity, something with rosin that's not with solvent extractions. Terpenes?

Some terps and waxes go hand in hand ....

Leave out those waxes and you will leave out some terps.

There is so much going on here, and so little known about what exactly is going on, logic sometimes is counter productive?

A cleaner rosin might actually be boring?

Keep on playing, and have fun!
