Can someone please explain to me exactly what redox is and how it relates to
plants?

It's been a *long* time since I took inorganic chemistry, but I'll try.
In a redox chemical reaction there is an exchange of electrons between the
REDucing and the OXidating agents. One of the elements, for example Iron
goes from having a +2 charge to having a +3 charge. Conversely, something has
to absorb that extra electron to balance out the overall charge.
But I have no idea how this relates to aquatic plant keeping.
