A little copper. A simpler garden.

How these Copper Antennas can give you 2x the crops without any installation

Before • Day 1

Day 1: two potted plants, with a copper antenna in the right-hand pot

After • Week 6

Week 6: the same two pots, with a taller plant in the pot containing the copper antenna
Our two-pot garden comparison over six weeks. Individual results vary.
  1. Choose your spot

    Start with a pot, planter or garden bed. Place the antenna beside your plants.

  2. Press into the soil

    Push the stake 4 inches into the soil beside your plants. No tools, wires or batteries.

  3. Leave it in place

    Keep your usual watering and plant care routine. The antenna needs no power or daily upkeep.

Why copper?

Copper conducts electricity. Electroculture is based on the idea that a copper antenna can channel natural atmospheric charge toward the soil. Research has not established that passive copper antennas increase yields or double harvests.

One copper antenna in a small square planting patch

1 antenna ≈ 10 sq ft

Our spacing guide: picture a patch about 3 ft × 3 ft (roughly 1 m²), or one large pot. For a larger bed, space antennas about 3 ft apart.

Details

Garden Coverage

One antenna covers about 10 square feet. Use this to pick your pack: 1 antenna for a few pots, a planter, or a cluster of houseplants; 5 antennas for a kitchen garden or mid-size raised bed; 12 antennas for a full backyard garden.

Materials

Every antenna is 99.9% pure copper, no plating, no alloy. An 8mm copper rod base with 4mm wire hand-wound clockwise into a tight coil at the top, made to Christofleau's original 1920 spec. Each stands about 12 inches (30 cm) tall above the soil once planted.

Planting and care

Push the copper rod 4 inches into soil. No tools, batteries, wiring, or upkeep are required. The copper develops a natural patina over time.

How It Works

Push the copper rod into the soil near your plants. The coil catches natural electrical charge in the air and carries it down the rod into the soil. No chemicals, batteries, or wiring are needed.

The design is based on Justin Christofleau's 1920 copper antenna for gardens.

What's Included

Each pack includes hand-wound copper antennas and a planting guide. The antenna is made of solid copper and inspected before it leaves the workshop. It ships in plastic-free, recyclable packaging.

One Piece Of Copper Can Change Your Entire Garden.

Plants have been waiting for this input for 80 years. Most gardeners have no idea it exists.

Historic electroculture gardening illustration

THE BACKSTORY

In 1920, a French inventor named Justin Christofleau patented a copper antenna for gardens. He sold 100,000 books on his method. Farmers reported doubled yields. The chemical fertilizer industry sued him and tied him up in court. By 1945, his work disappeared. For 80 years almost nobody knew it existed.

Copper antenna conducting natural electrical charges into the soil

WHY IT WORKS

The air around your garden has small electrical charges in it. Copper conducts electricity better than every metal except silver. When you stake the antenna in your soil, those charges flow down the copper and into your plants' roots. Same thing that happens after a thunderstorm. You've seen plants take off after a big storm. This is why.

Historic research into the electrical response of plants

THE SCIENCE BEHIND IT

In 1900, an Indian scientist named Sir Jagadish Bose proved plants respond to electrical signals. The instrument he built to prove it is in the British Museum.

We were curious. So we tested it ourselves.

Two identical pots. Same soil. Same seedlings. Same watering schedule. Same windowsill. One had a Klēone antenna planted beside it. The other didn't.

You Asked, We Answered

WILL MY PLANTS REALLY GROW BIGGER?

Within 4-8 weeks, gardeners report taller stems, fuller leaves, and more vegetables. The effect compounds. Season two beats season one. Season three beats both.

WHAT DOES SCIENCE SAY?

Most research stopped before 1968. After WWII, fertilizer companies funded the field, and they didn't fund work on free atmospheric ions because nobody can patent the air. The modern silence is about who pays for what gets studied.

HOW IS YOURS DIFFERENT FROM THE CHEAP ONES?

Three things. Material: 99.9% pure copper, not painted alloy. Direction: wound clockwise from base to tip, the 1920 Northern Hemisphere spec. Stake: 8mm copper rod base with a tightly hand-wound 4mm copper coil at the top.

HOW MANY DO I NEED?

One per 2-3 feet of garden space.

4×8 raised bed → 4 antennas

10×10 garden → 12 antennas

One large pot → 1 antenna

Indoor houseplant → 1 antenna

WHEN SHOULD I PLANT THEM?

Anytime. Push it into the soil whenever you like and it gets to work right away. Plant it at the start of the season (March through May in the US) and you'll have a full season to watch it. Start later and it still works through the rest of the season. Either way, you plant it once and leave it, so it's ready every season after, too.

CAN I USE THEM INDOORS? IN POTS?

Yes. One per medium or large container. Works on indoor herbs, houseplants, indoor tomato setups, and cannabis. Any plant rooted in soil.

WILL COPPER HURT MY SOIL?

No. Copper is an essential plant nutrient. Your plants need it. At one antenna per 2-3 feet, you're nowhere near a level that affects soil microbes. We recommend rotating their position each season for long-term soil rotation.

HOW LONG DO THEY LAST?

5+ seasons. Copper basically forever. It just deepens to a richer bronze patina over time, like an old penny.

WHAT IF I CHANGE MY MIND?

Send them back within 365 days. Full refund. No questions asked, no forms, no phone call.
