If I remember right Sta Green is not bad. I thought maybe you got the "top Soil" they have it is in a green and white bag. That stuff becomes like concrete when dry. Though I do get that stuff myself especially when it is a torn bag since it is like $.75. But I always use it as a filler with other good stuff just to make the good stuff go farther. I use a lot of potting soil, humus, compost etc in pots. I always make a mix and know what mixes well to keep it fluffy and still go cheap.
