Hygrozyme and Sweet in a media-less setup?

Does this make any sense? I'm pretty sure that both have to react with the micro organisms that live in the media... I intend to use both, but want to know if I'm off base here?

I really dont know what your asking but hygrozyme is an enzyme that aids in breaking down organic matter in the soil, its not a nutrient of any sort... It does help break down dead root matter though... As far as sweet... its magnesium, sulfur and iron I believe... I really dont know what you think these things will accomplish, if your using them in conjunction with other nutrients...ok. But alone they wont do much for you... Also, the sweet is better suited for non-organic growing...

Sweet...
