Amplifying Plant Signals

I’m trying to duplicate an ESP experiment described in the book “What A Plant Knows,“ by Chamovitz. Basically, I need an amplifier and sensor to read signals from stems and roots. What frequency response does the amp need? My guess is from DC to maybe 20 Hz? If this is the case, then what sort of amp configuration do I need?
