Cannabutter! help!

Hey guys first timer here. Sooooo I have 5 oz of mj powder and I was wondering if this is how I make butter? I want to put 5lbs of butter in my crockpot with 5 cups of water then I will add 5oz of powder. And cook on hi for 8 hrs then low for 2 hrs? After I will strain through a cheesecloth and refrigerate overnight. Is this the right way to make butter? Any insight would be much appreciated.
