Well... i used mids (only because i hadnt anything better ), and the weight of hash oil i got was about 10% of the weight of the raw weed. Probably better weed will produce more oil.

The smallest amount of weed i used was 1-2g. It did make a small ball of hash with about 1/4 inch (6mm). The only problem with very small amounts is scrape it from the dish, as it forms a very thin layer. For small amounts i would suggest to evaporate it in a wine cup (or anything with a spherical bottom). Smaller the surface of the acetone, greater the thickness of the layer of hash oil, and easier to scrape.

For me, a small ball with 3mm (1/8inch) is enough. But i have a somewhat low tolerance, so probably you will need some more.

And good luck! :thumbsup:
