Hey guys long time reader first ever post.

so friend of mine, swim decided first time he tried extraction that he would pull 4 times like the tek says. He then did an additional 2 pulls in which he left the naphtha in the solution for a couple of days, if not a week or so. he noticed that in the amount extracted from the first 4 pulls was not much more if at all more then the last 2 pulls.

His question does anyone know from more experience, a good amount of time to let it sit. Swim has another extraction going on. the first naphtha pull has been sitting in the solution for over 12 hours.

umm yeah swim didnt realize that thats what it says to do hadn't read it in a while. >.< also i couldnt figure out how to delete my topic so i just edited it

hopefuly swim will be able to break through on this extraction and be more active on the forum thanks all
