its as the title indicates, im interested in making some form of tincture esp. from colonized substrate(most likely grain). but also from fruits. it seams like i could make an herbal percolator and use acidified water..also thinking of making a modified vaccuum percolator...just wondering if anyone here has any input as to the best type of acid to use i have tartaric, fumaric, citric, ascorbic, acetic..and lemon juice...or what amount of acidity to use..should i be shooting for a specific ph...also is there any benefit from using ethanol? im not sure if my method will work as well for the substrate extraction..

Hey brother I use alcohol and heat. There are a lot of videos on that. I want to try it with gummies soon as the alcohol + weed in an "herbal infuser" seems to do great for this kind of stuff. (Blender and heater in one). I've found about a 20% power drop off that way though. I usually heat it all strain it well then boil down to 1ml per 1g of dry material. Golden grain alcohol.
