This was a 2 hour extraction and THC-A collected were both scrapped from the same collector from the same run. The terpy THC-a bits were from the bottom and the white THC-A was clogged in the vapor line.

So just a straight up subcritical run did it hey? Thatās pretty wild. Did your collection vessel get up to a pretty high psi then you degassed it? Did it take time? Or did you just run it and crystals came out? Lol
This was from a steady state CO2 with no delta P between the extraction vessel and the separator.
This was from a passive Co2 system which basically means that it was a gravity flow system.
This system was extremely flawed and I couldnāt get Xact Xtract to fix the design.
One of the biggest issue with this design was a lack of surface area for the heat in the system. This causes the separators to flood and this sends liquid Co2 through the vapor lines depositing THC-A in the line set.
Thatās why the THC-A in the vapor line is clean and the THC-A from the bottom of the collector is terpy. The flooding separator flushes the THC-A in the vapor line clean while all of the terpenes and oils are rinsed from that hunk of THC-A.
Outside of the pressures involved low pressure Co2 is the most versatile solvent for crystallization especially when mixes in CXE mixture.

Yah Iām very much of the opinion that co2 is exceptional for final product creation, itās just real bad as a solvent lol.
Do you think thereās potential for taking a crude (oil/shatter/something) and setting up an autocrystalizing system this way? Maybe with either jacket temperature or pressure swings?
Have you had any further success with ethanol at 5% with subcritical? Or was it more a one time experiement?

Yes, Co2 is poor solvent choice for extraction but fantastic as a antisolvent or a main solvent in a CX type extraction.
Co2 and Ethanol in CXE is my main focus outside of Class 3 solvent blends. On most system I can 10x the oil output with CXE over supercritical Co2.

Yah CXE is absolutely superior.
On the same line as an anti-solvent. Is there any alkanes/alcohols you know of that arenāt miscible with subcritical co2? I was thinking of doing an LLE with it to alleviate the residual solvent situation afterwards.
I just started running an xact xtract and I canāt tell you how much this and your previous posts just helped me. I appreciate you.
Anytime, I am glad I could help you
