Rosin curing question

My 6 ton dabpress is being delivered today and the press bags will be here tomorrow. I've been watching a lot of videos on youtube just to get an idea of what the process is like. Making rosin is very straight forward. There was one video from an individual working for a dispensary in colorado that used beautiful blonde patties of hash to make the most amazing looking blonde rosin I've ever seen. I thought okay we're done right? Dude puts it all in a glass jar and pops it in the oven for a period of time. He referred to it as curing and I've never heard of this before, but I also have no experience making rosin. It's said to increase potency and flavor by heating at 200F for an hour or two then allowing it to cool. Store for 1-2 weeks and it's done. Cold curing was also discussed. I also noticed the product is more stable where it comes out of the jar like little chunks rather than a sauce consistency. It's explained here, but I'd love to hear from someone that actually has experience doing this and what their opinion is on cold cure vs hot cure and how much the potency and flavor increases with either method. In one video a guy did both methods and the hot cure was much more stable like wax and could be picked out in chunks with a dab tool rather than a sauce.

Curing Rosin: The Waiting Game

Whether it be a hot or cold method, the true magic happens when rosin is left to sit for an extended period of time. Over the space of a few weeks or so rosin begins to separate and sweat liquid terpenes, and in turn, the cannabinoids start to recrystallize into solids.

Thanks for any info the rosin pros can provide. I'll be setting everything up today and pressing my first hash patties tomorrow. I'm stoked!

My rosin doesn't last long enough to cure.
Squeeze it, freeze it, smoke it

What's the consistency like after the freeze? I'm excited to try it after the press. Never had rosin before

Coming out of the freezer it's brittle, quickly gets soft & sticky like toffy.
I mix rosin with weed in a joint or dab it, and I save the pressed chips to make coconut oil extract for edibles.

Is the hot cure how you get the consistency like a hard wax? I'd imagine both methods produce the same high. I'm wondering if the harder consistency might be a little easier to work with. BTW, I just got my dabpress in. I feel like a kid on christmas man. Jamming out my first rosin run tomorrow with some high quality blonde hash pressed through 37 micron bags. Beam me up scotty!

I'm onboard with your method of ingestion. It's the same way I've always smoked hash. Mix with a little good weed and burn 'er down. Dab rigs are cool but too much for me. Now the dab pens are super convenient. I dig those a lot.

I just found this cool site that explains how to do different curing methods for different consistencies.

This guy does the rosin jam I kinda dig. Looks real easy to work with and easy to dab:

I think what you’re describing is decarboxylation. It is necessary for edibles and tinctures, not if you smoke or vape.

Good info. It seems like it's all about presenting different consistencies and nothing more. It doesn't seem like sauce, diamonds, or hard rosin offers the same high. It's all rosin. Some just look cooler than others. At least that's my novice understanding so far.

Diamonds are pure THCA. They smoke fine but are dead orally without decarb.

Why would anybody want that? Forgive my ignorance but THCA diamonds are still rosin just processed in a different way?

Edit: I just looked it up and that is one complicated process for very little payoff. I will say those diamonds do look very cool.

They are a purified fraction from either rosin or a solvent-based extraction done cool enough. Butane blasters started the trend.
But THCA regardless of presentation is why a decarb with heat is a good thing.

You can throw your glass jar on your plate and whip them makes a kind of butter consistency

Wow what an experience it's been taking the rosin press for a test drive. I dry ice sifted some trim and small popcorn buds through a 160 sieve and used that as my starting material. I'll never do dry ice hash again. I'm buying a little wash machine like frenchy canoli used because dry ice hash is A) not as high quality as bubble hash, and B) dry ice fucking destroyed my new $60 boldt bag. The rubber inside cracked and pieces of nylon were fraying allover the bag. Never again will I use dry ice.

Moving on. I tried some 7g hash presses of some nice sandy material. I was very dissatisfied with the results. The rosin came out very dark versus the blonde waterfalls I've seen on other people's videos. It was incredibly potent and with a beautiful lemon taste. I don't even understand where the lemon flavor came from, but it's delightful. However the rosin is dark. I did some reading and dark rosin is not always an indicator of quality. If the material used is very old and very dry it will produce very dark rosin. I believe this is one of the many reasons the pros prefer fresh frozen. Preserves the terpenes and doesn't allow the resin glands to degrade due to over drying. My trim and popcorn buds sat on a drying net for 2 weeks or so. I just kinda forgot about it. Needless to say it was dry as a bone which contributed to the dark color.

The yield from the material I used was unimpressive and I fault myself for that. One of the many reasons bubble hash is of higher quality than dry ice hash is you get better separation of plant matter from glands. If you over shake dry ice hash eventually it will pulverize all of the plant matter into such fine pieces that it will make it through your sieve resulting in contaminated hash. Crap in crap out. Quality in quality out. I'm gonna process a 1/4# of quality flower into bubble hash next week then I will press it and post results.

I was so bummed about the yield and dark color of the rosin I produced I just had to figure out what the fuck was going on. I saw people pressing shit looking buds on youtube followed by a mini waterfall of honey looking rosin. So I grabbed a small nug of some good flower and pressed it in a 37 micron bag because I didn't have anything larger. While it did not produce a lot of rosin what came out was gorgeous honey looking rosin. That sure made me feel a lot better. I did some reading and 90-220 micron filter bags are recommended for flower material. Even through a tight 37 micron bag I got to see that sweet honey rosin. Just not enough

I ordered some 120 micron bags to process some flower along with the bubble hash I'll process in the 37 micron bags. I'll post results after the press. Honey rosin here I come!

I'm thinking of experimenting with my 600kg press.

I wonder what kind of flower do you press, is it wet, dried, dried and cured?

What is the difference in pressing fresh, dried or dried and cured?

Can you use resin in any other way, eg. melt into butter and do cookies or something similar or is it only good for dabbing?

You want it at least dry.

The most important question is what yield should you aim for?

As in, is there a threshold in terms of; if 100g of the flower gives 10g of rosin, that would be 10% yield?

What makes it worth it and what not? What should you aim for in terms of yields to make it worth it?

Is there any use for the material that's left (after pressing)?




P.S.: I guess for me 15% is the bare minimum, while 20%+ is preferable...

P.S. #2: I will test on a few G's if I get 20%+ from XY strain, I'll do it on a larger scale, else just do few G's (to cure and try later on, who knows, might be low yielding but brutal dank shit)

I always cure the flower then press as needed into rosin. 37 micron are pretty tight, if you were using just hash or whatever to start you want the tight bags. Using looser ones gets more rosin out. Make sure when you pack your bags to press you are nice and even and flat and not overfilled. A pre-press to form is helpful. If you have gaps or space in the bag, rosin will tend to collect in with the plant material vs squish out. Put it close to the edge so the rosin pushes out and you can try to keep it off the heat as best as you can. If you go too hot or too long, you can get darker stuff. Different strains will be happy with slightly different temps. I would not do any hash processing first, just normal cure the bud then press. You don't want it too moist or too overly dry. Out of the jar with a boveda pack works great. Some strains just doesn't press good. I was given a bunch of flower that looked good but was kinda harsh. Tried to press it and it was always just super runny and really really hard to work with and was always dark and unpleasent and no matter the non-stick ptfe sheets and everything else trying to get it usable, it never was good. Going to different flower eliminated that issue and allowed normal parchment paper for the press. When you are pressing, pull them off to cool immediately. Then depending on your collection/scraping to get it, having some ice packs out with dry paper towels on them can be very useful. If you set the parchment on the ice pack as you start to roll and collect the rosin, the cold ice pack will help harden up the rosin and make it easier to scrape/roll up.
Never tried any other cure type attempts after pressing. It just get's dabbed from that point on.

Thanks, much appreciated. I'll be doing some experiments soon and will update you all on how it turns out.

I live below sea level in elevation and atmospheric pressure is much much different than most cities. Super humid very hot summers. But I actually find my dried out old bud. If left below 60 f really stored in the fridge around 32-34 is best. But my drier older material that I save in the fridge gives me nice tan chunky budder right on 1st press. I do grow some really frosty strains but I don't ever use my tops. I find the middle and lower buds have much bette4 quality resin from being shaded. Also don't wait a month or 2 for dry and cure. Once u harvest for rosin I break down the plants into single smaller branches for 4-6 days then buck all the buds off the stem. 2 more days drying and then I pack them in turkey bags, Grove bags, vaccum bags whatever will hold up to sub zero temps. I have several ice chests with dry ice in them. I flash freeze all the bud. Dry ice will pull majority of moisture out the buds. But if ur not comfy wait 7-14 days after chop and just put it in top of your fridge if it filters the air it will slowly dry your bud and retain terps that usually cook off in cure. 2 fridges really make this much more simple. But a reg fridge as long as it removes air decent has always given me the best cure and I got bud that's 3-4 years old in the freezer vaccum sealed in ball jars. That bud still looks fresh. Ages fast once pulled. Dry sift works great for quality rosin. But most shake way too much material out thinking it's still hash or will help them. Just shake the bag lightly once u see any sort of color change stop collect that really good trich heads and then u can make more dirty sift. Ur sift will look a little ugly but if it had good terps it can taste pretty good. I find that my bud is frosty enough where I don't need to waste any time or energy washing or sifting. But I use my trim bin sift and sift my trim. It's all trial and error. I was told buy 10 bows of cheap hemp and practice with trash u don't care about. Really helped me not destroy all my prized hash and flower. Also I re-press all my bags 2 or 3 times. Some strains dump twice. But I love high heat slow pressing my used pucks and hash bags. Makes the best verison of RSO well solventless full spectrum oil. Plus if u heat it up long enough u can get that CBN conversion going and I find majority of people who smoke a little enjoy CBN much more than THC they just don't know what's what. Anyway hope ur crushing it. Hope I said anything that can help. All positive vibes from over here. Hope ur making full melt and 12 star rosin thumb prints by now. If you get a shaker box with a 100u screen. U can sift out most of the contaminants and plant material. U will lose the bigger juicy heads though. But I end up just rolling the hash left on top into hash balls. U would he surprised how little of the bigger trich glands and heads carry oil and terps. That's why washing cured bud is the best rosin. I hate fresh frozen. Pulled 2 weeks early no high just smells good and tastes nice but don't do shit. If they had patience it would prob be amazing. But any light colored rosin ain't for me. Unless that's simply how the heads cure. I hope this was long enough. Doing talk to type makes sending people small novels so easy and who is gonna read all this shit lol

I agree fresh frozen is hype, I get way higher off cured bud, I let cure 1 month then filled my chest freezer with quart jars and pressed a jar every couple weeks, lasted all year but I'm itching for a harvest right now. Bag of oranges will be my first plant to finish outdoors, it's going down
