I use many other ingredients when I blend a soil, including worm castings and bat guano. When I amend used soil I use different amounts and not all the original ingredients. I just showed my shopping list. that's all.

Lipps, I see you offer lots of advice on growing. Thank you. Do you grow anything yourself? Any documentation on your trials and errors or are you just an avid reader? No offense meant, but I do look to see other folks results when I consider using their advice and I see you've not posted any personal grow posts.
