I want to go organic. I am a huge newb when it comes to this. I would like to get a mix where I could grow from seed to bud without adding much at all. I live in a small town and all I got it good old walmart. They have blood meal, bone meal, lime, worm castings. I was wondering if I could get a decent mix with these? Maybe add some of these to some miracle grow potting soil? I mean could somebody like give me a mix by percentage that I could work with. Oh, I think they may have peat moss and some other thangs. I don't believe they have guano and stuff like that though. Thanks.
