Is there anything I need to do to this soil before I transplant my plants in to it? I'm a new grower with only 3/4 of a grow under my belt...haha. I used miracle grow on that grow and they grew like crazy, unfortunately I had to dispose of them before they got to bud due to legal issues. It is now legal and need to at least learn the basics. I WAS TILD NOT TO USE MIRACLE GROW.....Is this true?
