I'm in South Africa making Feco to help where I can. used 95% ethanol. issue with water solubles(chlorophyll). Brine doesn't make sense with ethanol extraction. The freezing method does. Freeze dried bud in zip lock & freeze ethanol. Pour etOH into ziplock. 3 min "wash" or basket and pour etOH over bud. Filter through coffee filter. Evaporate etOH. Best method for making great quantities of great quality Feco?
