“I can't give this product 5 stars because I haven't run the Advanced Nutrients (AN) line without it, to contrast it against other solutions. AN recommends it in their feeding chart, and while I know what it's providing, I'm not sure how important it is over all if you leave it out. For the cost of the line I'm running, it's really no big deal with throw this in, and maybe one day I'll do a no B-52 test.”
