In high times they used to sell an iso 2. Which was almost the same process. Much like an old coffee perculator. When you got to the dark green oil you can turn that into honey oil. It's been a long time. You take the dark green oil and mix it with a pint or so of water. I know WATER are you f ' ing crazy, NO. Shake it up real good. real good . I know it sound nuts. Now strain it through a coffee filter, the filter turns green and looks like you lost everything,but all you lost is the chlorophil and shit. Now put it back in the pot and evaperate the water, be very careful this time and you will end up with a honey colored oil much stronger and clean. Honey oil and no butane to blow your ass up. It takes large amount of weed material to make much of anything. The better the weed the better the oil. I sold the iso 2 to my dealer but I think I kept the instuctions a long with Tim Leary's formula for LSD. I can post it but it takes a mad science lab to make it , that's why it is mostly made at college's they got the lab. I don't know if they still sell the iso 2 machine been years since I have seen a hightimes.
