i was told by a guy in my hydro store that i should definitely add hygrozyme to my nute mix because it's "awesome". i passed this time and went home to do some research and on my hydro store's site it says it's a micro nutrient but then i found one store that says it serves to "clean" my hydro system. can anyone that has used it or uses it fill me in on why i would want to use it and why it's so "awesome"? thanks.
