  1. I've just downloaded the circuits for the watering watcher..I read the text where it says A square wave is used to avoid oxidisation..my knowledge as an "improver" allows me to think that electrolysis would be the enemy of the probes..can some one explain why a sine wave is US and why oxidation not electrolysis is the nemesis of electrodes [probes]..browsing down the responses on soil conductivity...the main component of vermiculite is mica a fantastic heat and electrical insulator.. thanks guru.....dicky
