HarvestStorm Pulsed-DC Expansion Unit

Electrode holder for DC electroculture experiments. Clip in two replaceable carbon steel electrodes, connect to any power supply, and start running your own electric field trials in soil.

Key Features

• Holds two replaceable electrodes via secure clip connectors
• Connects to any DC power supply — use your own source
• Carbon steel electrodes included, swappable for other materials
• Good for DC field trials, radial field experiments, and polarity testing
• Simple design — no controller, no proprietary parts

Product Details

A no-frills electrode holder for anyone who wants to run their own DC electroculture experiments without being locked into a proprietary system.

How It Works

Clip in the included carbon steel electrodes, connect the leads to a DC power source, and push the electrodes into your soil. The unit holds position in the root zone while you run the voltage. That’s it — simple by design.

What the Research Shows

Running a DC voltage differential through the root zone is one of the most replicated techniques in electroculture research:

• Active electric field exposure increases biomass and yield across multiple crop species
• DC fields influence mineral and nutrient transport through electroosmotic mechanisms in plant tissue
• Weak pulsed electric fields enhance stem water enrichment — relevant for drought resistance and water-use efficiency

These results come from peer-reviewed studies using setups similar to what this unit enables at home or in a small research environment.

Getting Started

1. Push the two electrodes into soil roughly 6–10 inches apart in the root zone
2. Connect the leads to your DC power supply
3. Set a low voltage to start (many studies use 1–12V depending on electrode spacing)
4. Observe over days to weeks — compare against an untreated control container
5. Swap electrode positions, spacing, or polarity to iterate on your experiment
