You used a helluva lot of expensive weed. An once of good bud is an ounce of good bud. A pound of canna butter is a lot to me, but not to you. That's all I mean to say.
Long - because your recipe is complicated and largely unnecessary. Awesome canna-butter can be made using as little an an 1/8 and requires no longer than 10 minutes to prepare.
I don't want to criticize your method. I hope it turned out better than you expected.
