I like it, growing with frequency. Should look into leds which do much of the same via the diode. I am putting in a frequency section in the organic chemistry thread very soon to better explain. For the most part the suns light is measured in nanometers. 360-720. This is the physics of the wave, its proportions and such. Copper wire runs a certain frequency of Hz or electrical through it do to the elements frequency. This is determined by its symmetry, density, and size of atomic circumference. To convert visable light spectrum nanometers to Hz it is a reversal. 360Hz to 720nm and 720Hz to 360nm. It will carry a frequency but you should really look into gasless led diodes. Wikipedia has great info. I will start a thread on how to build them if you are interested.

Copper is used as an insecticide as the plants can tolerate it more then the pests. Coppers is dangerous at high levels and is not something you would enjoy smoking.
