It all depends,also you would have to compost the materials that you will be using and that takes time.
I realized after I posted that I would need to compost the **** anyway and that would take too long but I just bought some bloom fert and bonemeal so I should be good. No bats around the house.
To make simple for you you can use Metabloom to start of with along with Floracius bloom as an additive.
