Yep i second that all i use is Roots Organics potting soil. One thing you need to know about them is they make their soil at the end of the year so it tends ti be a little "hot" in the earlier months so you might need to cut it with some Sunshine #4, also Biobizz makes great soil too, its just like the sunshine mix its good for seeds and young plants. But id look into Roots or Biobizz, Ocean forrest is a good 3rd alternative i try and stay away from foxfarm nothing against them i just think there are better products out there. hope it helps
