The only drawback of a powered survival hydro system, is the power or rather the lack of it in a genuine survival situation.
Really ought to have gone with a gravity fed system of some description...no power whatsoever anywhere in the system.
A header tank, high enough to allow sufficient pressure to feed drippers with nutes to develop would have been a better idea i think.

In the past I simply used a 25 Gallon drum with a pump in it and let a grow table flood twice a day a little more over one inch with a simple household time clock between pump and power.
Once a day measurement/adjustment with handheld electronic pH and nutrients meter in the drum, and also an oxygen fish pump for keeping it mixed up.
