First of all I wanted to find a way not to harm the plant that much. Because most of the conductive metals are reacting with the plant itself causing a poisoning. Therefore I tried to find out the specifics of graphite as a non reactive invasive electrode to measure (whatever) inside the plant. During my research I found a very nerdy, fetish article about a pencil IBM merchandise as a part of the IBM Electrographic (you need to scroll down, after all the picture is finally the article)[http://www.lexikaliker.de/category/bleistifte/page/36/ IBM Electrographic]. The next step was to find out by myself which degree of hardness would be best in its conductive characteristics. So I did the same experiment as shown in the article and found out the softer the lead, the better is its conductivity. This has to do with the way graphite lead is manufactured. The specifics of carbon/ graphite you can find [http://www.chemie.de/lexikon/Kohlenstoff.html here] (it is in german). | First of all I wanted to find a way not to harm the plant that much.

The next idea was also to measure on the surface of the plant, so I just ordered some electrode pads with a layer of silver and carbon.
