The earth carries a constant negative electrical charge. The ionosphere, 100 km above, carries a positive charge. Between them flows a 130 volts-per-metre electric field — and a current of atmospheric ions, telluric currents and cosmic radiation that plants have evolved to use.
Electroculture installations — copper coils, pyramids, magnetic water — gently amplify this natural circuitry, giving plants more access to the energy that was already around them. The result: bigger harvests, healthier plants, fewer pests, less water.
It is not mystical. It is physics that modern agriculture forgot in its rush to NPK fertilizers.
