Those bacterias and fungi need apart from roots a medium to grow on, you don't have that in DWC, or at least not really, the real root action is happening in the water. Speaking of which can only hold up to 8ppm DO (dissolved oxygen) at ideal conditions and very low temps, in reall life you should be happy with 4-5ppm.It is a bacterical innoculant, so it is pretty useless in DWC.

Good soil has about 10% of O2, good bacteria and fungi need O2
4ppm = 0.000004
10% = 0.100000
i'd say thats a huge difference

...I'm not convinced btw., that hydro is the best for keeping microherds..
