Opinions will vary. Coast of Maine makes good soil. So does Royal Gold. Fox Farms was fine for me beginning, but it comes with a built in pH tank around week 6-8 depending on how you water. If you follow a Fox Farms feed schedule to the T, it’ll be fine. If you don’t, expect some (curable but annoying) issues
