I’m weedaholic on icmag, I started the THCA isolation thread way back when. That thread was the first place THCA crystals were posted online and lead to diamond terp sauce existing.
@pangea posted his observations of crystal formation in unpurged jars and @Calilabs( associated with guild extracts at the time) posted the their first diamonds.
Extractioneering really popularized the HT layer as HTFSE. His demeanor and bragging(the wiggle) lead to many an arguement and help spread it. @theotherone here in Colorado purchased the tech from Extractioneering and popularized HT here in Colorado.
