the easiest way in my book is to take everything you are going to use stems/trimmings/etc and put it in a coffee grinder or anything until its as fine as u can get it then take some everclear (liquor) and let it sit in that for a day or so completely submerged....then run it through a coffee filter or anykind of filter to get the stems/trimmings/etc out of it (may take more than one pass)...than sit in a container with lots of surface area with lots of ventilation for the everclear to evaporate...u are left with a golden sticky substance (aka pure hash oil)

I do not consume or grow marijuana in any shape or form. All the supplies i buy are for my beloved tomatoes.
