okay, I'm attempting an LSA extraction using naphtha(zippo lighter fluid) as a non-polar solvent and isopropyl alcohol as the polar solvent. Is acetone a better non-polar solvent? when soaking the seeds over night in water to remove fungasides should I grind them first? should I let the non-polar solvent evaporate before using the polar solvent? How long should I let the seeds soak for each process? how much solvent, polar and non-polar is the right amount for 700 seeds. All advice are welcome, whether it pertains to my question or not.
