I have a couple hundred pounds of old material (untrimmed buds) that I would like to salvage into distillate. Which solvent/method would be the most economical for a quick, easy extraction?
To start off, I do not have easy access to a CLS. I have a small rotovap, however, for solvent recovery.
I was originally thinking of using a zippered mesh bag, and 7 gallon FG buckets filled with ethanol and dry ice to extract.
However I'm wondering if a different solvent such as hexane (~$150/5gal), pentane (~$200/5gal) or heptane (~$150/5gal IIRC) might be a better choice. Would those solvents require chilling in order to prevent pick up of extra unwanted lipids and others like chlorophyll? Or would room temperature suffice?
I'm curious if a room-temp ethanol wash with post-extraction carbon filtration would be more economical? Or would a cooling the ethanol in a standard non-cryo chest freezer be enough, or do I really need dry ice temperatures?
