Doing extractions, I have read a lot on how to freeze the bud and solvent and have tried it, I will have the second half of the system today (IF UPS stays on track) to reclaim the solvent. I have also read about using an espresso machine to do hot extractions to gain more of the oils faster. I have not treid this, dont have the $300 coffee maker, and thats to much for a test. Anyone done the hot method? IF so what was the results? It does sound like it might be best done outside.
