Will Rosin Replace BHO?

Will Rosin Replace BHO?

Can a $20 hair straightener deliver bigger and better tasting yields than a costly closed loop system? A new technique of separating trichromes from green matter just might put an end to the use of explosive chemicals to create concentrated THC.

I was getting blazed Friday night. Checking out the usual hot spots on the internet I stumbled upon something called the Rosin Tech—basically you take buds or dry sift, wrap them up in wax paper and run a hot hair straightener over them releasing all the sticky resin.

The first thing I thought of when I heard this was holy shit. I bet the non-stoner wives and girlfriends of stoners are running to the bathroom right now to hide their straighteners. The stoner girlfriends of stoners are already in the know, that’s why they always have more erl than you.

Making Rosin is quite simple and so are the necessary tools

How to Make Rosin

I’m not going to go step by step through the process, because by now, you should all have gotten it figured out. If you haven’t, far smarter and more motivated people than I have written it up and made videos detailing the process.

The most clear and concise one is here on the Black Leaf Extracts GrowOps YouTube channel. The instructions they have in the details of the video are very well done. They do point out that doing this in bulk doesn’t really work that great. They found that runs of seven grams each are about the max you wanna do. But again, the quality of the yield is very nice.

There is also a great write up and explanation here on Errlax about the Rosin tech. I’ll quote a bit here so we are all on the same page as far as definitions. They say:

Rosin tech is a heat extraction method that utilizes an ordinary household hair straightener, or any other flat heat press mechanism, to “press” out the terpene and cannabinoid rich resin from the cured flower or hash. This process occurs near instantaneously and requires virtually no professional expertise in the field of botanical extractions. Rosin Tech requires nothing more than an ordinary hair straightener, some parchment paper, and either flower or hash. The benefit of using this technique with hash is that it will produce a full melt with a comparable yield. So in cases where you have less than 5* Hash, this will method can transform your inferior product into a 5-6* full melt.

Rosin tech uses heat to melt the glandular domes of the trichomes off of the base material. This resin rich sap will then reconstitute on the parchment paper, ready for collection. After scraping the parchment paper, the clean waxy residue collected will be clean and ready to dab.

How Well Does the Rosin Tech Work?

Interesting stuff, so now that we know how it works, does it work well? A user on Reddit by the name of BirdMachine69 ended up with .45 grams from 2 grams of some nice looking buds. You can check out the whole thread here.

They reported using 300 degrees and two ten-second passes to get this done. Another kid by the name of Amnesiac854 on Reddit said his girlfriend was able to pull a 25% yield using her $20 hair straightener. He says, “Seriously though, this rosin shit is incredible. She just pulled a bigger and better tasting yield from a $20 hair straightener than I get from my closed loop…”

Is this too good to be true? Apparently not—at least from everything I’ve read and watched online regarding the Rosin Tech. As best as I could trace it back it was figured out by an individual who goes by the name SoilGrown on Instagram. But the more I Googled, the deeper down the sticky DAB-bit hole I went. Follow me now!

Rosin Tech—A Quick History

It all started with this article on Cannabis Culture about how the Rosin Tech was the death of BHO. With a name like that, of course I had to click it. In it they had a link to a video by John Berfelo called? Yep, you guessed it. The Death of BHO. Classic link baiting, but it did the trick.

From there I found a great discussion with a bunch of extractors on this four hour long Google Hangout called Hash Church. I had never heard of it before, but it was pretty enjoyable. They were all trying it out and reporting on their results.

A human by the name of Jimmy Carter over on a random Rosin Tech thread on Grasscity.com says the tech has been around since before 2005, so if anything, Soilgrown has just brought it back to light, and given people a new twist on an old concept. It’s good to see Jimmy Carter still producing fine results. According to him the tech was originally used to “clean up non melty hash and make it into full melt.” But now Jimmy, along with what seems like the rest of the internet that is in the “know,” are all over this.

The one thing people keep saying is that the taste is phenomenal, and the amount of work you put in for the quality you get out is also nice. It’s a far more simple process than the OG Boffo Butane PVC Hash Oil method Indra blessed the collective consciousness online with way back in May of 1999. Have you ever read that script? Do you even remember 1999? I was like 19 years old. Anyway, it’s pretty awesome, you should definitely check it out here on Erowid.

I would like to quote a piece where he describes the best way to collect and store the oil. He says, “Trying to transfer the oil into a small container while it is still solvated by the butane is too risky. I learned the hard way about this, thanks to the volatile temperament of butane. I had filled a vial almost all the way to the top and was preparing to drop those last couple drops in, so that cleverly, I could let the last of the butane evaporate from the vial and the oil would all be neatly contained. But when the last drop hit the mother lode in the vial, it changed the temperature of the solution in the vial upward by a hair and it all “superboiled” out of the vial and onto my fingers, which of course startled me and caused me to drop the vial. I suggest dissolving it in alcohol as I mentioned above.”

Can a $20 hair straightener deliver bigger and better tasting yields than a costly closed loop system?

Keeping that in mind, being able to produce a some of the sticky icky that looks as good as what our friend Jimmy Carter over on the Grasscity forums made, without the use of pvc and butane, is a huge leap forward in stoner safety. Personally, if I didn’t work where I do here in the beautiful, freedom filled evergreen state, I would definitely be doing this instead of trying to safely jam a couple cans of butane into a glass tube.

Unless you have a lab to do that in, you should definitely be careful. The last thing we need is a rash of articles in the mainstream media demonizing dabs because people can’t seem to not blow themselves up trying to make them.

Crude-Oil Impurities Are Probed in Rail Blasts - WSJ.com

“The energy industry has been reluctant to discuss publicly what might be causing the problem. It is possible, experts say, that unusually large amounts of naturally occurring and highly flammable petroleum products such as propane and ethane are coming out of the ground with the Bakken crude. Last March, Tesoro Logistics LP reported the Bakken crude it was transporting by rail was increasingly volatile. The San Antonio company didn’t respond to a request for comment.

"Another possibility is that impurities are being introduced during hydraulic fracturing, or fracking. That process involves pumping chemicals or other additives along with water and sand into a well to free more fossil fuels. One such additive is hydrochloric acid, a highly caustic material, which federal investigators suspect could be corroding the inside of rail tank cars, weakening them.

"Oil from fracked wells can also be laced with benzene and other volatile and highly flammable organic compounds.”

Overburden, a mining term for the natural material that lies above an area of economic interest, is burned at night. Mining will commence once the forest is cleared. Four months earlier, this area was made up of boreal forest, with trails used for hunting by the First Nations.
