3 spiral electroculture antennas for your plants!  One per plant pot. 12awg bare copper wire.  The wire attracts the voltage from up high in the atmosphere and the spiraled wire brings it down into the soil, granting more energy to your plants to thrive.  Electrosmog does not inhibit this, it seems to generate the same enhanced energy whether in a high electrosmog area or not.  The main thing is getting off the ground - if you are at least 6ft high is best.   
Option to have the spiraled antenna with an additional 7ft length of bare copper wire attached so you can wrap it around a pole - either wood or a grounding rod will do.
