So before I get into the actual process of making solventless diamonds, I wanna start by saying the THCA made in this process isn’t a true diamond. It’s a high concentration of THCA in the shape of a diamond. Just wanted to get that out of the way so nobody gets hung up on semantics.
So first things first this will only work with crumble or sugar. Sugar will usually yield a larger terp fraction. Crumble seems to be higher in THCA. Also important to note, this will work with any kind of crumble or sugar. Not just solventless. I suggest practicing on cheap bho before attempting with solventless.
The reason crumble and sugar work and shatter doesn’t is because crumble and sugar aren’t homogenous. With shatter, the cannabinoids, terpenes, and fats all lay in a perfect lattice, almost like a diamond. So when you try to isolate it everything melts at the same time where crumble and sugar already have thca separated out of the mixture so it’s low boiling point compounds separate first, allowing this process to work.
on to the actual process
I always try to start with an oz. you can do more or less, whatever you desire. I recommend starting with a small piece of bho.
You take your crumble and wrap it in a rosin evolution 15u square and secure that in a rosin evolution 25u bag. Once everything is wrapped up tight and there’s no loose folds where the pressure could cause a blow out, you are ready to begin.
Start by heating the press up to 60c
Once the press is up to temp, you can place your rosin bag full of crumble onto the plate, very slowly apply pressure until both plates are touching the bag and heat is being evenly applied to the crumble.
Very slowly apply pressure. You’ll notice the bag start to “sweat” terps after 5 or so minutes of slight pressure being applied at 60c.
Slowly up your temp to about 70c and add a slight amount of pressure. (About 1-2 pumps on a bva hand pump)
You should begin to see your head terp fraction forming. These will be the purest runniest terps that you collect.
Once you start seeing your terp fraction slow down, slightly increase pressure, increase temp by 5c.
Repeat this step until your at 90c. It usually takes me an hour to get to this point with an oz.
As you creep up to 90c and start putting down close to 2000psi (low temp plates) (psi will vary by press) you’ll notice your terp fraction starts becoming very thick, clear and yellow. This means a greater ratio of cannabinoids is being dissolved into your terp fraction.
This is where you stop. Your terp fraction should be real stable and yellow now. It’s basically just melted thca at this point. Stop the press, release pressure and turn off your heat, your now done with the press.
Take the folded rosin bag off the press and open it up. At this point you’ll have a chalky white THCA patty. You’ve probably seen this on IG many times.
So everyone’s question is how to get the white patty into clear diamonds.
All you do is preheat a vac oven to 200-250f. (Pull no vacuum)
Crush THCA patty into powder
Place powdered THCA on a dab mat or thick parchment and throw it in the toaster oven.
WATCH IT VERY CAREFULLY. The stuff goes from solid to liquid instantly.
As it melts it’ll slowly transition from matte white to a very clear color. If you leave it in to long it’ll turn purple. Note that the purple is very prone to oxidation. It’ll turn dark red in just a few days. Even with terps.
Once you take it out of the oven, try to run a dab tool through it to pop any bubbles, then quickly roll the melted thca up into a snake. Once it’s snaked out I like to hit it with a heat gun to smooth the surface of the thca and make it glisten.
Just take your thca snake and break it up into tiny rocks and reintroduce to your terp fraction.
If you wanna have your diamond in a shape, all you do is replace the silicone mat or parchment with a silicone mold.
Place powder into cell of mold and put into oven until it melts into the shape you want.
That’s pretty much all there is to it. Feel free to ask any questions below.
