Just read through your thread brother, and wasn't surprised at all to see what a excellent job you did with your first AFs indoors. We know that skills and the right grow gear is only half the equation, the other half being great genetics. We also know that Stone and N.W. have/do breed some nice AF genetics. I don't think that either of you will be disappointed with their meds. Also like we talked about already, Yoda's YDB is also excellent.
All so, concerning Pro Mix HP, that is all that I have used indoors. In fact believe it or not, I picked up a bail just today while I was in town. Good stuff INMO. I started adding some extra perlite (1:1) to it with my current grow, and I can certainly see a difference in both veg and flower.
Peace!
