I ordered some seeds from carolina petsupply and I am trying to get ready for them so I can plant them as soon as they arrive; however, I am unsure as to what type of soil to use. I know I should use organic soil but I was wondering if anyone knows of any brands that work? I was thinking about using Organic Choice Potting Mix by Miracle-Gro. The ingredients are: 50-55% composted bark, sphagnum peat moss, pasteurized poultry litter, and an organic wetting agent. I am not sure if this is safe to use. Any ideas?
