well that my friend would depend on the quality (by the price you gave i'd say it's pretty good) and just how high you want to get.....i don't see how you plan on making brownies with 2 grams though....unless you are going to just like make self serve portions but i think a pretty basic rule of thumb is 1 gram of decent bud per person, but i could be wrong...i've only read alot about this stuff i've never actually done it.
