actually, yeah you do. A pump failure could cause overwatering to happen immediatly. It could also cause an underwatering situation depending on what type of hydro system you use.
Root rot brings on pathogens that can affect the plant long term. Once a plant has had pythium it and its clones are more susceptible to it in the future.
Overhandling can cause stress. Over crowding can as well.
being in hydro, your humidity will have to be in check. High Rh in flower can bring on mold.
There are only a few pest that being in hydro allieviates, all others (like the dredded spider mite) dont care how the plant is grown.
