you'd be better off just adding a lot of perlite to the scott's or mg instead of outside dirt, you'll bring in pests like spider mites.If you sterilize it in a microwave first and add perlite it will probably work though.Ok this is a total noob question but since MJ technically needs only a medium to grow in and then additional nutrients which you add, can i go dig a hole in my backyard and use that soil for growing? I can only find miracle grow or scotts soil where i live and the scotts i am using has too many nutrients for my small plants. thankss
mix it up, 50-50 or more if you've got it. You need a bit of soil to hold the moisture and nutrients. Hydro growers do it almost pure though, called Hempy Bucket style.
