I would not recommend using acetone, but I am not an expert so I really don't know.

Here is just a rough guess of how much solvent. For one pound of cannabis, I would estimate that it would take (12) 16 ounce bottles of 99% isopropyl alcohol. The amount needed varies. It would primarily depend upon how many times you plan to wash the material. The density of the buds is also a factor. Each time I have made the oil the amount of solvent needed has been slightly different. Even when I use the same strains and the same amount of bud, the quality and amount of the oil seems to vary up to 20%. It is a little unpredictable. I would try to make sure there is some extra on hand just in case.
