Thank you for even reading this.
I am experimenting with plants grown via Hydroponics (soil-less and in water) and the assumption that when growing plants in mother earth, a plant is "grounded" to the earth via their roots. When growing Hydroponically, there is no "connection" to earth. I want to run electrodes (12 ga. solid wire) into the root structure of Hydroponically grown vegetables and then tie them to the ground of a (USA) 120VAC system. My concern is that of trickle voltage that could run back from the house ground into the plants destroying them (electrocution).
Can someone please show me a simple method to create a one-way path from the plant to ground so that nothing can come back from ground to the plant? Nothing exotic, just something simple and oh yes, affordable too...
I would be most grateful. I assume that the actual voltage potential would be low but have to be capable of a spike or anything the current system has to offer. I am in California and at the mercy of PGE, the most unstable system in the country.
I thank you in advance...
