Hey fellas. I was wandering if the basic Miracle Grow Potting Soil will be alright to grow in. I want to get best possible yeild and i am willing to mix it myself if it will be better, but i was wandering if this would work. Has anyone used it? It says it has pheat moss, some compost and i think perlite in it, it sounds alright. What type do you guys usually use. Also, im growing in sort of clay soil, and i dug 2 foot deep holes and relling with the new soil. I want to try to break up the clay as much as possible, maybe mix it in with the new soil somehow (maybe pitch fork), so the roots can penetrate more. Does this sound like a good idea?
