Is there a very simple method for taking ISO below 40ppm?Looks like a gold mine to me brother! Those are trichomes stuck to the jar, which could be easily harvested using alcohol and turned into orals, topicals, dabs, or suppositories.
Isopropyl as a good way to extract economically and good for making concentrates as long as it is subsequently removed below 40 ppm.
Less critical for purging, though more expensive due to taxes, is 190 proof ethanol, which doesn't require as stringent a purge and enough residual can be left to make a tincture.
You could do one jar at a time and cascade the same alcohol until it reaches saturation.
