the cost of his products is way too high imo, but they do of course work, just as AN does and in fact the nutrients in powder in NPK bags are the very same as those in AN albeit less diluted. You can buy products on ebay or other which dont come in small packs at that price. For example, K2O is a common product, it is extremely cheap unless you buy it from
NPK industries. The same with his P his N and so on. His system is not organic AND, does he even ship microbes? I dont understand systems of bio stimulation, where one also adds bio restrictive salts
