I was wondering the same thing. I went to the store and bought Fox Farm Grow Big Hydroponic, but I never knew they had a SOIL version until I went home to look at the feeding schedule. The Hydroponic version probably won't work as effective as the SOIL version (when using soil), but hopefully it still works good!
