Rosin Technique....Easy DIY Solventless

Scooby dooby dabb · Mar 17, 2015

Hi guys firstly let me say love this forum seems like some very knowledgeable people on here. So that being said I was looking for some advice.. after searching these forums and youtube for a couple days in regards to the rosin tech, I thought I would try the technique with some og kush.
I normally always buy my concentrate but if I can save money and have clean way of dabbin, I thought why not.
So much to my wife's disgust at 11pm I'm in the bathroom with her hair straightner trying the technique. At 350f for 4-5 secs till I hear the sizzle a little bit of smoke/steam (don't know which)
But what I noticed that different from any I've seen was the way the concentrate looked on the parchment paper. mine does not glob up into little dots like most ive seen.. It's more like a oil that just surrounds the bud and its a bugger to get off the parchment paper..

am I doing something wrong?
im a bit of a noob at this. all advice much appriciated. thanks again

Weird. You're using a good deal of pressure? It's definitely parchment and not wax paper, right?

Yeah plenty of pressure and on parchment paper.. sry guys haven't worked out how to post the pic on forum yet just link too it

Update: managed to get the pics posted now

Watched some more of that hash church and at around 2:45ish (two hour) soilgrown starts talking specifics and then demo-ing his shirt press tek. Right around the 2:56 mark you see him press some bud. Damn quick 2 second press at 310F (uncorrected pid). Recommends breaking a 1 gr bud into 6 pieces and spreading evenly in the center of the paper. This is all with the tshirt press though.

Also I thought it was interesting about how the more pressure you apply the more heat is generated. So if you use a lever/press you can use less heat as you add pressure.

is this video online?

Just kidding y'all!

After it solidifys does it come off the parchment easily? I.might be able try this with T-shirt press.

Try a slightly lower heat and try to stop pressing before the sizzle. It seems to me the sizzle is product being destroyed. Also more pressure is good if you can.

Scooby dooby dabb · Mar 18, 2015

So after lots and trial and error I have worked out that for me, the best temp is 320f and 3 secs and this is how my OG kush rosin tech turned out from 1 gram of bud pressed twice on 3 popcorn nugs.. once again I wish to thank everyone for there input and advice.
Will do some more later today and post some more pics.. :clap:

Watched most of it, pretty enlightening. I just got a digital hair iron in the mail from Amazon so I'll give it a try soon and report back.

This technique is rapidly evolving..
I can't wait to see the result of a couple silicone pads hooked onto an iron in some fashion, has anyone attempted something like this yet?

Yeah no shit. It's been around a month now but it exploded after Hash Church with good reason. I read elsewhere someone has rigged up an air compressor to a t-shirt press to get more pressure and lower temps. I'm betting you'll be able to buy a customized rosin tech machine within the year.

@CubanGrower did that. He posted a pic on has instagram feed.

Another interesting variable they went into on HC was the moisture content of the flowers and how it plays a role in helping pull the rosin away from the bud. Soilgrown says for the best yields use perfectly cured buds. Too dry and the pressure just crumbles the bud and contaminations get into the rosin. Too wet and yields suffer as well. With the right moisture content and temps you are actually steam distilling the rosin out of the bud. The heat turns the water into vapor. Since the trichs use water to help maintain their structure, when the water is removed the trichs fall apart and are carried away by the vapor onto the paper.
This is of course all just theory of what is going on inside that iron/press. There was also some talk of some terps liquifying and since some terps act as a solvent, that this could also be helping break down the trich heads and carry to the paper. So the terp profile of the bud you are using could effect the yield as well.

Would be interesting to play around with moisture content levels using the same bud to determine a good moisture content. Soilgrown said he has played around with it a little bit, but not really approached the issue with any rigor.

I want to play with this, but I'm all out of flowers and will be for some time as I'm pretty stock up with a nice errl stache. I thought about trying it on some bud I have left from a first EC wash, but it is too dry and broken down.

Tried the hash church tek and it worked great. did it with both a 25ui pressing screen and a ~50ui stainless mesh. Each method produced identical results but the mesh seemed to trap less oil. Forgot to take pics but the product is as clean as any of the flower rosin I made albeit better tasting.

Also tried pressing bubble in parchment just like the the flower tek:

Not quite as clean as the screened method, but you get more yield (I'd guess close to 40-50%) and a significantly improved product.

snamuh · Mar 21, 2015

I tried with a tshirt press and tin foil (only thing i had that i could think of could be used)

320f 3 seconds, and it returned nothing.

NorVape · Mar 21, 2015

This is almost to good to be true! Gaah, all my flowers are superdry atm, ready to be vaped. Need to get me some fresh weed and cure it perfectly...

Or should I maybe be the guy to figure out how to do this with traditional import hashes? Hmmmmmmmm *stroking chin*

I've found it's really dependent on the strain/grow quality. I picked up a quarter recently and pressed .25g of each strain.

Grape god on the left and tangerine kush on the right. Tang kush yielded more than double the grape god. Grape god was much drier but after looking at the test results from each strain, it also had half the THC of the tang.

I don't have much experience with traditional hash, but my guess is that it'd work pretty similar to bubble. keep us posted if you try it out though :rockon:

Havelock Vetenari · Mar 21, 2015

As a big concentratelover i'm following this thread closely, it will be a few weeks before i can try it on quite fresh buds, which are not too dry yet sadly. :ugh:

I am wondering though if it would be possible to 'rehydrate'(i'd strictly use RO- or demineralised water) older, dryer buds a bit, if the steam theory holds that might be enough to get (reasonably)good results as opposed to the disappointing ones some seem to get with these?
Think i might be shopping for a flat iron for some beginner tinkering... :science:

Love it!

Timothymdq · Mar 21, 2015

Has anyone done the rosin extraction, and then did a butane or ISO extract on the compressed buds?

I need to join this party ASAP.

How will you determin the moisture content?

Can I suggest the CVAULT containers for this.

Use the different amounts of various paks for testing. Then everyone has a benchmark.

Having had success with literally just .2 buds, even with the proof right in front of me I can't believe that this is real lmao. For someone that only "dabbles" with concentrates occasionally or when the need arises, I'm having a hard time getting over this surreal excitement over how simple it is to press out some quick very, very high quality organic oil safely and effortlessly with a fifteen dollar hair straightener from Walmart...

Same here I want to get this working just for those special occasions. I most my stuff is really dry though. I have two more kinds I can experiment with though.

Ok, so I think soon I'm gonna have to play around with this. I believe I have just had a brainwave of a great way to do low-temp rosin extraction. I'm busy experimenting a lot right now, doing my bit for cannabis science but I will report back when I've tried this out.

I really can't imagine the terps staying completely intact, but I'd love to see what rosin from the bubble I have comes out like compared to my cleanest nicest solvent based absolute shatters extracted from the same material!

Has anyone here who has chops making serious quality absolutes with solvents managed to get material they believe would rival their best solvent extracts using rosin tech out of interest?

Man I love playing with new extraction techniques!

EDIT:

Ok, so I jerry-rigged a rosin pressing setup which uses well controlled, fast and efficient conductive heat from both sides and man did the results turn out worth the effort!

I have had 3 small dabs of my THC Bomb rosin extracted from bubble, using an emptied and thoroughly cleaned teabag to contain my bubble. I'm now gonna use my new experimental 1 wash tech on the remaining bubble/filters after pressing. What a way to get the good stuff out!

I cannot yet comment on yields, haven't taken the time to weigh but I can certainly comment on flavour, which is so close to the original bubble but just so dabbable with 0 particulates. Leaves no residue on the nail (ok, a tiny little more residue than my cleanest solvent extracts would leave, but not huge amounts).

The flavour is incredible. I think I'll probably only dab this stuff from now on. I need to get some legit SS screens though. Anyone got any advice on pore/membrane size? Was bubbleman using 25 microns?

I was messing around with this a bit too. I used the bubble man tek, I know it's not "his" tek but that's what I followed. I used my girls straightener at about 275 degrees Fahrenheit. Yes @herbivore21 those are 25 micron pressing screens. I haven't tried SS sceens yet. So anyway I tried pressing some no-melt dry sift with poor results. So I put .36 into my keif press to make a little cake. When I i pressed the hash cake I got .06 of some decent oil that's around a 15% retun. It's tases very good I'll try n get pics up when I cab.

do we think that bubblebags/probags would be safe to use as said screen? To me it seems like it might be dangerous to subject these plastics/nylons to such heats, even if only briefly lol
