I have been working on this idea

http://www.electro-tech-online.com/threads/singing-plants-advice-please.90472/

And i would like to make a circuit to be powered by the arduino, ive had a go at designing one, and would like some some advice.

I am thinking, a voltage divider to bring the voltage down into the millivolt range, followed by a wheatstone bridge to get a baseline setting for the resistance then low voltage single supply instrumentaion amplifer arangement to amplify the resistance variations to input into the arduino.

Am i on the right track?
