Thunderstorms create electric fields in the air with specific frequencies, and at a cell level, all living biology is electrical signal—these frequencies can change certain reactions and effects in organisms.

In a leafy greens trial, farmers noticed that caterpillars did not eat the treated plants compared to the untreated control, and the farmers were not told in advance which plants were treated, suggesting the pest resistance effect is real and not a farmer expectation bias.

Rainstick's approach to mapping the effects of frequencies involves working with three basic elements—frequency, waveform, and duration of treatment—with potentially 50,000 different possible frequencies, so brute-force testing is impossible; instead they get early indications and work methodically through each step to achieve desired effects without unwanted side effects.

Rainstick applies an electric field similar to what happens during a thunderstorm to seeds, which is a specially tuned electric field, and then those seeds get shipped out to the producer for them to grow without requiring any change to on-farm processes because the seeds have already been altered.

The seed treatment is not genetic modification and not chemical; it uses bioelectrical signals to influence how genes express themselves without altering the DNA, aiming to give seedlings a stronger start that could last their entire growth cycle.

A leafy greens farmer reported that caterpillars did not eat one particular crop, which turned out to be the treated sample even though the farmer was not told which was treated and which was control.

Rainstick takes seeds and applies a specially tuned electric field similar to what happens during a thunderstorm, after which the treated seeds are shipped to producers to grow, creating a frictionless experience because farmers don't need to change any on-farm processes since the seeds were altered beforehand.

The treatment formula consists of three basic elements — frequency, waveform, and treatment duration — and with potentially 50,000 different frequencies and any waveform shape or duration, the solution space cannot be brute-forced, requiring methodical step-by-step testing to achieve the desired effect without unwanted effects.
