I know its an old post but need sum help... I kinda stomped on step one of this (and similar) tutorials.
What i did was a froze my buds. Then frozen, i cracked them up and packed them in the thermos (i don't want to grind them up as i will then rupture the cells of the plant and i will be pulling unwanted material)
Then i filled the container with chilled butane and left it to soak for a full two hours inside a cooler surrounded with ice. Every half hour i "swirled" it.
When i poured the butane out again it was crystal clear. CRYSTAL!
My theory is that a fine layer of condensation must have covered and frozen over the buds bfore the butane was added. But its surprising that it meant NOTHING atall was extracted! I mean the pyrex dish had very thin layer of white stuff on the bottom, probably some plant waxes and butane leftovers :-/ (i use the stuff labeled "near zero impurities" its should be good. This white stuff does trouble me though :-/
The buds by the way was JUST harvested i don't know if that means anything? (Not cured atall) i wanted to preserve as many
terpenes as possible.
Any advice? My first time pulling, i've been reading up on this for years but only recently have i seen tutorials and methods i trust will leave a pristine product.
