Any one ever use Royal Gold Basement Mix?

saw this at the hydro store today and was thinking about trying it out. Any one have any reviews on this soil? good or bad?

I saw this mix too at a shop when I was going to buy a bag of coco coir. I like to mix about 30% coco/70% foxfarm into my soil mixes (seems to let the root system breathe and expand better IMO). The guy kind of talked me into it, saying that people really like it a lot (mostly will use for 4 weeks of veg). I dont want to go soiless but liked the nutrients that it has been enriched with. I transplanted 6- 36in plants into 5 gal pots and vegged two weeks before flowering. I wanted to use up some of the nutes less specific to flowering and will start adding 1/4 buddah bloom or bat guanos. I will post more on the how this works out. Just put them into flower 2 days ago
