Why do a lot of people on this site not like miracle grow? It's a top selling soil, surely it can't be all bad? My thoughts run like this: The soil has been developed by people that spend their whole day thinking about soil, not just thinking about it but developing and testing it. Maybe the soil is so good you don't need to add your own fert's. Has anyone had any success with miracle grow soil? I grew 2 healthy plants in miracle grow a number of years ago. I grew them from seed without a fan and without any lights. They never flowered because they didn't get enough light, but they grew. They were well over 2ft when I threw them out.
