Super soil is usually a little hot so you would put that on the bottom third and go with a little less amended soil on top. I think I used Roots organic greenfields and did the supersoil on the bottom. I found through trial and error for my set up super soil and all the recipes were a bit much. Many people would argue that with me on that, but that fits there style.
The recipe I gave you should get you to the end without burning up. It is all about balance. Experiment, ask question, debate things, read ridiculous long posts written by babblers that are way to high to be posting (sorry about that).
Go to the organics section there are a ton of talented growers and great soil methods there for when your ready.
I do apologize I feel like I kind of side tracked your thread.
