Origin story — not a validated experiment

My First Experiment

The experiment that started Electric Fertilizer's investigation into electroculture.

Historical significance ≠ scientific validation. This experiment is why the site exists — it is not evidence that electroculture works. Both things are true, and we say both here.

Background

David first encountered electroculture in 1990, in a set of old papers he bought and shelved for years. In February 2011, gardening with his family, he remembered those papers and decided to actually try it — modifying a cell-phone charger and running wires with nail electrodes into a container of Romanesco broccoli under an indoor grow light. He didn't expect much. The results are what led to the research, writing, and products that followed, and eventually to this site.

Setup

A modified low-voltage DC power source (a repurposed cell-phone charger) connected via nail electrodes to a container of several Romanesco broccoli seedlings, growing indoors under a grow light starting in March 2011. Nearby, a larger tray of the same Romanesco variety grew under the same light and watering schedule, unelectrified — an informal comparison group, not a randomized or blinded control.

Observations

Surviving dated photos from March 2011 show four electrified plants with visibly larger, darker-green leaves than the same-age seedlings in the comparison tray, and by later in the month the electrified plants stood well above the surrounding trays. No stalk length, leaf width, or biomass was formally measured — the comparison is photographic, taken from the same vantage point on the same dates, not a quantified trial. Tracking stopped after the plants were moved outdoors.

A tray of unelectrified Romanesco broccoli seedlings of the same age, March 23, 2011 — The unelectrified comparison tray, same date and location — same Romanesco variety, visibly smaller.

Limitations

This was a first, exploratory pass — not a controlled trial. Specifically:

Small, non-randomized groups. A handful of electrified plants against an informal comparison tray, not a randomized or blinded design.
No formal measurements. The comparison is photographic — stalk height and leaf size were never actually measured with a ruler or scale.
No yield data. Harvest weight or count was never recorded.
Uncontrolled variables. Position on the shelf, distance from the grow light, and watering by hand could all have varied between the two groups.
Tracking stopped early. The plants weren't followed through to full maturity outdoors.

None of this makes the observations meaningless — the size difference in the photos is real and it's why this is presented as a documented origin story, not as an experiment result on the Research page or in Claims.

Where this fits today

Everything Electric Fertilizer has published since — the mechanisms explanations, the controlled and grower-reported experiments, the products — traces back to this one exploratory test.
