Not sure what kind of soil he purchased, I am going to assume a generic potting soil or miracle gro potting soil at best. Haven't added any ferts yet, I'm not familiar with what I should add. I had thrown out the original miracle grow packaging with the information on it so I was unable to determine whether or not it had any fertilizer in it but just purchased another bag today so I will look into it and post again soon. Thanks for replying!
