my situation is i have a very good spot that gets direct sunlight most of the day. The problem is it would be too expensive and too much of a bitch to buy enough soil and lug it all to my grow area for the size I would like to do.(15-20 plants). what could I add to the soil to get it either up to par or almost up to par wiith soil u find in stores. BTW my soil type is more clay than sandy, and kinda dark brown, not quite black. Living in Ohio if that helps. Any info on making my soil more fertile and nutritious for my plants would be great.
