The thing with growing pot is that there's so many claims made by manufacturers that it's hard to know what is working and what isn't. This product claims XX% more terpines, this product claims XX% bigger buds, this product claims XX% faster growth, and while to some extent many of the products work, there's a point of dimishing return, where you're throwing money and products at the grow, for negligable results. MJ growers are like hunters/fishermen, they'll buy anything if it claims to grow bigger, plants/buds faster, catch more fish, shoot more ducks, etc. I liken it to the health claims, eat this and your XX% less likely to die, eat that and your XX% less likely to die, take this supplement and your XX% less like to keel over, so if I add all those up, I'll never die? Just my .02 worth. (I'm on a roll today)
