Berger BM6 Mix

[greenspace]

Did a quick search but I didn't see any threads on Berger or their products. I picked up a couple of 3.8 cf bags of BM6 and the price was almost half pro-mix (BM6 doesn't contain myco but otherwise looked similar) so I am hoping for good results. It seems this mix is designed specifically for cannabis:

I am just looking to see if anyone out there has any experience with this mix?
