You can increase the potency of the butter but double running it. This is where you add herb water and butter to a crock pot cook it 12 hours stirring often. Then press out your butter and return it to an empty crock pot and add more butter and water to cook another 12 hours. After filtering the butter and letting it go solid, seperate it from the remaining cook water. Then add the solid cannabutter to a very large stock pot with fresh water in it. Melt to butter and stir well. Allow butter to cool till solid then drain off the water and repeat . This is the water washing tech that I invented. It will remove most of the water soluable contaminants and fiber making for much improved flavor and usability for making confections, pasta sauces, etc....
