From my research I've found that dried herbs are better filled 3/4 then fill to over an inch with the alcohol but it should usually be left 2 alchemical months at least 80 days depending on the herb used and whether its better for cold or hot maceration. Also taking into consideration the astrological birth of your spagyric tincture i.e drawing an astrological birth chart for the picking preparation and creation of the tincture with the celestial bodies and constellations for what you are making like sign of cancer for dissolution which is a water sign and good aspects from Mercury if using lavender which is best done with cold maceration.
