I would theorize when we discuss warmer extraction temperatures we guarantee more contaminants. While I imagine we could still clean it up using the same medias, I think the amounts would haveto be increased. So then it becomes a matter of is it more affordable to cool the solvent, equipment, material, or to include the additional filtration media needed to remove the increased level of contaminants from not cooling.
My thread Cannabis Alchemy Extraction Method vs. Modern EtOH Extraction Methods was actually meant to address that cost to clean vs cost to cool concept in relation to warm and cold ethanol extractions where I was hoping someone had some financial data to show how they would compare if they even could compare at a high level of refinement, but the thread kinda went off course. It was my very first thread, so it probably wasn’t very well composed.
