Rosin Technique....Easy DIY Solventless

[2clicker]

I'm not gunna lie a huge factor in this for me is the whole absolutely 0 hydrocarbons aspect.

@2clicker I was thinking of just saving the pucks and throw them in my buddies Magic Butter machine. That or wait until I have a bunch and then do a QWET run and figure out what to do with it. Its hard for me to want to use solvents if I don't have to anymore. I was already about ethanol over butane, but this takes it a step further. Also if people are getting 15%+ now that seems to be extracting almost all of it. I certainly wasn't getting 20% return with solvents on my buds :/ So 5% less for no purge time, left over pucks (for whatever) and totally healthy DELICIOUS oil are my deciding factors. I dabbed some good BHO the other day, so I'm not an anti-solvent warrior now or something, but I want the majority of my oil to be solventless or co2 extract in the next year or so.

i havent seen anyone get 15% from this tek. can you link me?

solventless seems great, but not at the cost of 5-10% of a run. im not rich. the runs i do need to last me as long as it can. it does not seem like the rosin tek provides this.

not to mention all of the variables. if its got enough moisture or not... etc.

i guess i just need to try it. wether or not the moisture content is ideal sorta puts me off also. if i do a wash /washes im getting all of what im after almost guranteed. i can keep washing until its all gone. then winterize if needed. with rosin tek you may get most of it. you may not. and then have to process the rest another way...?

why not do a dry sift and then a wash? dry sifting is going to produce a cleaner and tastier return over rosin tek. and can be done within minutes.

rosin tek sounds cool for occasional extraction and to save time, but replacing solvent methods? i just dont see it.

i think i will get an iron and give this a shot. im gonna do the rosin tek and then qwet the smashed flowers for the rest. ill do that on half and dry sift the other half, followed by a qwet wash.

I think when you try it you will see why so many people love it. You make all fair points. Certainly nothing wrong with QWET, but oh man I'd pay so much more for a gram of rosin than I would a gram of QWET or BHO, or even co2 oil at this point.

I view it as a higher level concentrate. I'd rather rosin the shit out of buds, save the pucks and QWET those to avoid wasting it. I can't explain it but it seems stronger, and it tastes SO good. I just want to bite into it.

 

[farscaper]

which would be the better unit?

electric flatbed press
or flat iron

Still don't understand why you wouldn't run the vapor from a fan-assisted vaporizer through some kind of basic condenser; thereby maximizing the extraction and efficiency.
This seems like a step backwards to the old globe+hotplate style vaporizers.

That will decarb the oil. Flavor and terps will be gone. I've seen testing on rosin that showed I believe it was 8% terps which is crazy high IMO.

If you are making edible oil I'd consider going with vapor distillation, but not to make something to dab.

It depends greatly on the strain/nugs in question I've found. I have actually gotten a consistent 16% from these rather spongy/weird nugs that were harsh and not fun to vape regularly, but then when I tried a different strains nugs that I believed to be better by themselves before I discovered this method, I was only getting a measly 8%. Still, I've seen kids on instagram bragging/freaking out about 20% returns, but who knows how truly accurate they are..

I can understand the hesitation or reasoning for not wanting to utilize this method, but I'd be inclined to side with darkrom because I would say rosin is great for me for exactly the same reasons. I also enjoy being able to completely avoid having to manufacture or go through the mess/hassle involved of producing a clean and healthy oil, mainly being that I'm in an area that isn't exactly the best place to find or get caught with anything related to concentrates.

@2clicker checkout the facebook group. There are a good amount of people getting yields comparable to solvent extractions. 15%+ Just like solvent based extractions yield is can be effected (either way) by tek, moisture content and the strain. I think rosin yield numbers are probably a little more accurate as there isn't the variable of any leftover solvent.

Here is a temp test that soilgrown posted to the group, with some yield numbers.

 

[2clicker]

ok im in

 

[farscaper]

now I wonder if im pressing to long and not hard enough... quality has been shown but I need quantity!
I may just order an electric flat bread press since I want max squash!

 

[darkrom]

You can't possibly press too hard imo. You can definitely press too long and kill terps.

ive not actually seen any flatbread pressers with adjustable enough temp and a low enough bottom temp to be practical...

so it is starting to seem that its a choice of:
flat iron for hair
clothing iron and a thick thermal slab
or a heat transfer press...

I tried it with my induction skillet and a ceramic bowl to press it so it would retain heat, but even at 300 it seemed I was still too hot ... could have been that the skillet was hotter than necessary because of a lack of thermal mass in tge skillet.... idk...

needless to say yesterday frustrated the fuck out of ol farscaper.... and I broke my fucking drawingboard cause I was pissed... so I need a new drawingboard to restart uppon....
I feel like this flat iron I already have ia tooooo narrow....

frustration.

 

[Joel W.]

So the downside is #25 on a Remington is way to hot. Upside, I may have an idea for a new type of vaporiser.. Lol.

Can't help but think this is like those vids that say "its OK to charge your cell in the microwave. It really works!!! "(Don't do it)

I did get a dab to try. It does taste really good. Come on harvest time!

 

[darkrom]

LOL @ the iphone in microwave that happens EVERY ios update! Whats sad is it takes a news story to convince people its not real...

I promise the rosin tech is no prank. I thought it would be a cold day in hell when I found something I liked better than DIY QWET.

 

[farscaper]

sooo.... I pondered hard and actually had to have a tech consult with the wife on how to properly work this damn conair hair burner... well turns out im an idiot when it comes to hair irons without instructions... I was using the turbo feature which fucks with the setting I had it on....

so after some more experimental loss I had an idea...

RH

That was the ticket... the more moisture content and fresher the sample the more rosin was retrieved.

this may be the very best way to extract off of nearly freshly or freshly harvested material ... which is where all the craxy high terps percentages are coming from I hypothesize....

without further wait.... a little bho vs rosin... and yes the rosin smells so much better and is a unique snap sap texture...
obviously the rosin is the dab at the bottom... and ratios and weights are not tested here.... just quality.

if I could get a system to make rosin on scale I would do it in a heartbeat.

@blankrider & @CrazyDiamond you should try this!

 

[farscaper]

slickpads increase yield. They retain and transfer the heat better... but require a few seconds more heat up time. another nifty addition was that it will allow you to see the super thin film that is everywhere the bud was on the pad. I had no idea it was there on parchment...

so toss that paper and grab that og oil slick pad off the desk.

a wide heating surface helps too!

this is good to see, all I have is a slick pad right now, and didn't want to go buy parchment paper if I didn't need to. Still waiting on the stupid heat iron to show up, should have bought local...

im a big concentration freak... and I love to extract.... but it gets messy and tedious and purging takes tooooo long...

.13 from a 2.55... like a 5% return and its the oldest most cured ive got and usually saps up some with any solvent method... but this jewce.... so for a first go at a new tech with a new tool not bad.... at least I didnt blow my grass all over a pyrex lol.

that was single run too... I plan to run it at least once more for a dab or 2 more.

 

[darkrom]

Is that rosin?

Definitely press each bud several times. Keep pressing until you get ZERO return. Its worth the extra effort to really get it all out. I've had 2nd presses yield more than the first, and some very impressive 3rd and 4th presses as well.

yep. 100% rosin extract.

I used only a Remington silk ceramic hair burner at 320°f and an oil slick pad folded in half. very high tech!

retrieved an additional .11 so for a solventless first "real" run on some well cured material only 2 runs [second one I will admit was both lazy and a little sloppy... I got high?...]

.24 from 2.55... that puts it at 9.4%.... ive had strains that did worse with the best of solvents....

I've never had enough volume or sufficient desire to go about making my own concentrate, though I did have my eye on a Liquidizer for a while. This technique has me interested enough to give it a go myself. The nug-by-nug aspect of it is particularly attractive. Quality concentrates aren't easy to come by around here, so this could definitely be a game changer for me.

Any recommendations yet on anything specific to order off of Amazon? A certain cheap hair iron, t-shirt, sandwich press?

I don't have long hair, but I like sandwiches. So I guess that's a start…

 

[jambandphan03]

I saw a panini grill that caught my eye on amazon, but I have no experience with it. Not terribly expensive compared to t shirt press... http://www.amazon.com/GAU-80102-Ele...qid=1427331693&sr=1-2&keywords=sandwich+press

 

[DieHard]

My crystal ball shows this in the near future.
The George Foreman Rosin Press.

 

[aesthyrian]

So then the rosin will just drip into the grease tray? Genius!

I had my eye on that one too. I might pull the trigger… My only concern is whether it can make good flat contact between the two sides. In the picture, it looks like the bottom is recessed a bit, and I'm not sure how close together the two surfaces get when it's closed all the way. I guess there's always Amazon's return policy…

I know, I like getting dabs within minutes without needing to set a lot of material down. I've got my BHO tech down as good as it can get, but I don't like solvents if I don't have to use them. The Firewalker OG I got delivered so well with the rosin that I was kinda sad I only did it at the end of the sack instead of with all of it. 4 or 5 small buds, enough to pack a few Solo stems (whole nug pack though), and I got a solid return. I got okay returns from a different batch of flower today. I'll return to them in a few days when they dry out a little more and see, it wasn't much but it's great, more concentrated flavor and I managed to actually keep it almost 100% clean. Yeah I think there are plant waxes in the rosin, I'm unfamiliar with non-solvent methods of removing the waxes from the resin. I know there are mechanical methods but using solvents (Buchner Filter) and winterizing with low temperatures.

Anyways I had a few dabs of the rosin I made earlier and I'm about to go out to get something to eat (not driving ).

Anyone tried regular hash? The stuff I have turned into a liquid almost immediately when I pressed it and then I slipped my hand and it made a mess. It wasn't a lot but I was surprised how messy it got lol
