No decarb is why it wasn't very potent. Raw cannabis doesn't have THC just THCA, it needs to be heated to activate the THC. Decarbing will always make your edibles stronger as if not you are relying on the butter infusion to reach a temperature whereby decarboxylation occurs. You can do this in the oven and there are some things you can buy to do it for you but they are pretty expensive.
