I am planning to grow a small garden of mini tomatoes (I got the seeds from a plant my aunt had). I read on a previous thread that its possible to harness a living plant. So say I had a "plot" of about a dozen of these pint sized tomatoes, and wanted to power a single led...... would this be possible? Has anyone done enough research on plant energy to give me an estamate as to what voltage I could get?

It is not clear there there is a practical electric potential to tap. If cells had a small voltage difference then the billions of cells in a plant could possibly electrocute it.
What most people assume is plant electricity is just galvanic action caused by the plant juices and the electrodes. In that case the voltage would depend on the electrode material.

It's all about the electrodes. The plant is just the electrolyte ("battery acid"). Even the earth can be used as a battery by sticking dissimilar metals in it. I think some old telegraph lines may have been powered this way.

Galvani and Volta covered this groun pretty well and Faraday provided the unified theory of electricity, ie, all the 5 or so electricities that had been discovered were found to be one and the same. Plants do have voltages. A LED couldn't work because the current needed is too high.
If you take the lcd panel off an old watch or something else, wery slight currents can be detected which will cause one or more segment to darken. You might touch parts of the plant with those pads used for ECG machines or the small muscle stimuators like the TENS machine, available at drugstores.
When you salvage the lcd , also get the part of the pcb that has traces leading to conductive rubber bridge strip,

ok, in that case, is there a combonation of salts that I could possibly use to make a battery *cites the clay batteries they found in the middle east*
It is possible, but this thread is about plants. Since you've moved on from that topic, I'll lock this thread to keep it from going even further off topic.
