I did a 1st batch with shit weed I had just to try it out,,it was my 1st time doing this,,,I didn`t think I`d get much of anything from it but it turned out very nice,,,For my 2nd batch I used 8 grs of KIEF and filled the rest of the extractor with more cheap weed,,the results were fantastic,,,there are other ways to make the stuff but this one proved to be the fastest way,,,Next time I`ll try my hand at making bubble hash,,will wait for the KIEF to pile up again so I have enough to make it worth while,,,thanks
