I run a lab out in Maine and have recently ( in the last two weeks ) run into some of the same issues that have been talked about in the diamonds chalking up thread. It seems that we are one of the first labs on the east coast with this issue. We use Cannagas as our solvent supplier, they go through diversified like most of the other companies. They swear their solvent isn’t the issue. The issue started happening on both of our extraction machines after distilling a new tank/batch and it’s been happening now with every run. We’ve broken down and cleaned every inch of the machines multiple times, extracted with crc, without crc, different solvent blends and the same issue happens every run. Thca precipitating out of solution right out of the machine, causing extremely fast offgassing and solvent evaporation. Runs in jars puck up and turn to sugar or chalk within an hour. Nothing changed with our sop’s or equipment to cause this. Seems that this has been happening for 6+ months now out west, has there been a consensus cause of the issue or remedy? Appreciate any insight 
Welcome to cold crash thca
I’vr figured this topic out I’d almost bet that this is the issues
Take a cold crash , like the original cold crash where it’s just liquid, pour the top layer off and the clear bottom layer chalks right up…it’s gotta be the bond of molecules aren’t no where near as tight due to the rapid crashing.
Inclusion city…
Anyone tried not dropping the temp as much and back to room temp… Maybe 50f to 72f cycling? Bc at room temp only they come out perfect
More solvent could slow the process down
I just realized you didn’t cold cycle though
I really struggle to think that’s it. Guys running the same sop forever and never saw it then all the sudden it’s there…… your theory just doesn’t add up man.
I thought the sop was rather new but if it’s been ran forever then just changed it’s definitely not just cold crashing
I’m gonna blame the lunar phase now
I haven’t had chance to do temp cycling yet but I’ve always noticed if I don’t stir my terps back into the thca the thca alone looks rather chalky
Yah we aren’t cold crashing. The video above is about 30 minutes out of the pour off from the machine. Reactions start happening almost instantly.
I noticed this when I started running crc crashing almost instantly…I capped w more tane to combat that…then it doesn’t just fall out
But the cold cycle thing I have no idea about
I’ve been reading a lot about the use of N2. That’s another common factor for those running into this problem. I’m thinking since now a days extractors like to run much colder, the use of N2 has increased in runs. So I’m thinking the N2 is leaving a contaminant behind that’s being trapped in the structure of the diamonds which upon being poured out of mother liquor and comes in contact with oxygen it reverts back to its original thca form. I used to run with minimal N2 mostly just head pressure on solvent tank and never had this issue, now the techs in my lab run way more N2 than I’m used to and now I see this reaction. I’m not a genius like moronabis so I’m probably wrong.
Edit: a solution can be buying higher grade N2 and do a test run with that to see if that solves the issue. Like I’ve stated before, my main process to making diamonds is not mason jar bho tek. So I don’t plan on doing these tests any time soon but if anyone has that time one should definitely try. I feel
Like most people use industrial and I think one should try using high purity as a test.
We’ve been running dialed in ratios of crc for both dry and fresh frozen runs for close to two years and never had these issues. 2:1 T5 to Silica at between 50-70g of media per lb. of dry material. Much less or none with fresh frozen. Doing runs with or without media hasn’t made a difference with the reactive properties of the solute.
Sorry that is incorrect I never had the issue when I was using a large amount of nitrogen
Yeah I use ton nitro sometimes never had the issue
I’m throwing shit out there you feel me, we need to try everything. I know everyone uses nitrogen in large quantities but shit you never know.
It’s like we are watching a virus unfold, each node becoming tainted with each new delivery.
That’s one of the first things that came to mind, just weird that we’ve been running at the same temps,and pressures for years now and this started happening. We never get the nitrogen assist psi over 75 or so, but have been using the same suppliers and sop’s with nitrogen without issue. Back in the propane days it was fun pushing with vapor head pressure but damn near impossible with butane blends and -60c temps.
Seriously though, shits scary and keeps me up at night.
Yup, all I know bro is that for a fact the suppliers we’re using there’s something different being sold to us. That’s why labs should try using higher purity solvents and nitrogen one at a time to see which one makes the difference. Yeah I’ve heard everyone say the same shit already “I’ve been using the same, I use a ton, I do this I do that” but we’re still using the SAME shit. Idk man with the way the global market and demands of goods is going I don’t doubt there’s some type of shortcuts being used to make up for loses. Remember companies that sell us N2 and solvents don’t sell to us specifically. So in my opinion in the eyes of the big manufacturers we’re buying from they don’t know or care that people like us use their product to manufacture thca diamonds so they probably feel that as long as their products do the job for example N2 for welders or butane/propane for heating elements they don’t see that whatever it is that’s contaminating the thca diamonds SOP as a problem, people still buying the shit. But deep down to the core I feel that down the supply chain there’s something sneaky going on. They can’t fuck with higher purity solvents or nitrogen so there has to be some test runs done. But whatever man.
Isobutane
We’re seeing it with isobutane and nbutane
Is that a corken I hear?
Accurate, imo. Though we cater exclusively to and our supplier processes exclusively for the extraction space and we’re still seeing it. Testing is rough, and costly, not being able to extract where the gas is processed to do a bunch of controlled tests on both sides.
Have you tried running colder … usually when I don’t run as cold I get the yellow thca like that but running -60 my thca is clear as fruck
Maybe I can’t see your jar as good I fixed the video so everyone could see it but the guys w Medusa stones are huge stones
When I have small sugar unless it’s really terpy and I stir them back in the thca is cloudy
Do u have large stones in there
I’m tossing the instantly crashing caused by your oil to solvent ratio was just right and the cold boil caused the thca to just fall out the solution. Also crc cleans it back to mainly target molecules which sugar up fast…stir it all together it’ll probably look better imo
