I don't see why you could't use fresh..the only difference would really be the moisture in your buds, but your putting it into a solvent that would have atleast a minimum of 1% water. So it might increase the amount of water in your oil in which would need to be removed and if not would leave behind a sizzle. Water also dissolves and washes away the Chlorophyll binding proteins and exposes the Chlorophyll to the solvent used something you probably already know...why we use 99 instead of 91 or 70... but this is probably a very low moisture content and wouldn't even compare. Other than that I can't see why not but I may be overlooking something like maybe a cure on the buds for terpenes but than again Im not a seasoned grower..I just make extracts. Thats just my two cents. Those buds look fantastic MR.Vega thats gonna make something great whatever you choose to do.
