This is what I do. My best results have been with low pressure. I have gone as high as 120psi in @Killa12345 miners.

I donât do high pressure on diamonds. I havenât had to add any either. If you donât have enough solvent for saturation, you can always add a little bit in there and retrace your tracks. Adding heat for pressure, may not be the best idea, depending on how much heat you are using.

People use the word cryo to mean colder than about -60 around these parts, not exactly accurate, but thats at least how its being used in this industry

you know as much as my grandma got annoyed by improper diction, she didnât win that fight. I think language is meant to evolve over time. A lot of slang has been added to the dictionary so I think its inevitable that the canna community transforms the definition of cryo. unless there is a better word to use instead, who tf cares

So, for larger grain sizes, obviously you want to use lower pressures, higher butane contents, and longer curing times. However if your primary concern is throughput, and you want decent smaller grain sugar, and you want to separate it FAST, here is a great SOP:
Collect your fresh live resin into your miner. We actually run it straight into the miner with a hose. Run a tepid (80-85F) water bath if itâs overly liquefied, and reduce down some of the remaining butane if needed.
Seal up the miner, pressurize with 50-80PSI. Wait 48hrs. You should have fairly good separation after that point. Pour off in a well ventilated area.
Here were our results using that SOP with a 6" diameter miner.

Lower temps = quicker nucleation = smaller crystals
Higher temps = slower nucleation = larger crystals
If anyone wants to know the detailed thermodynamics, i provide that at a cost.

Yeah well itâs technically incorrect by a long shot. what people are referring to is subzero temperatures. Iâm well aware of what there referring to and everyone throws that word around when their temperature zones arnât even close.

The correct term is subzero.

Your talking about a temp difference of -60 to -238 or lower so there is a big difference. certain gaskets, hoses, and materials are rated for certain temps so using that term Willy-nilly does make a difference to people who are not aware of that.

Subzero is below 0C.
Cryogenic is below -50C. âHigh Temperatureâ cryogenic is -50c to -195C. âTrueâ cryogenic temperatures are -195c to absolute zero. -195C is used as the separation between âhigh temperatureâ and âlow temperatureâ cryogenic because that is the boiling point of liquid nitrogen.

Correct, the average extraction is done from 0c to -90c around here. There are some of us that mess around with Ln2 and dip into the cryo range.

Thatâs pretty impressive crystal growth after just four days? What exactly were you doing to get them so large?

Just gotta get your saturation at the sweet spot. And each strain has its own. Some are better then others for sure.

people donât realize most of ALL gaskets we use/have access too cant handle TRUE cryo temperatures⌠not many gaskets are even truly rated for -80c or colderâŚâŚ most are for -60c and havenât been tested colder; the manufactures ASSUME theyâll go colder because most are tested at -60c with 75-150psi; they assume itll go to -80c ---- -90c at lower pressures, yet its untested.

You can get facets in jars 100% just takes time and better quality material. This was grown over 3-4weeks of personal home grown organic material.

THCA falls out of your solution at -60 not -20 almost instantaneously, Iâll literally have diamonds coming into the collection vessel straight from my material column, I never add excess nitrogen into my pressure vessel the pressure from the solvent wanting to evaporate is plenty enough to start the âcrashingâ any diamond miner with out an adjustable PRV or any PRV is just making your crystallization take longer
