I don't know about AN, what I do know is that Mammoth built this formula in a lab and spent a ton of money doing so. They charge a premium because, from every account I have seen, using it as recommended works as they claim it does. If you can do the same for cheaper, by all means, do so, post the results, and put them out of business. Until then, like I said, and like they claim, this stuff really does seem to work. My plan for testing get this stuff was to run it in coco on clones. 2 using mammoth P, 2 using orca or great white, and 1 control with nothing. I'm not to the point in my skill as a grower, or in my space for growing, that I have enough clones to do this, but when I do I will. Again, from what I've seen here, as well as with other independent growers, the product works exactly as advertised.
