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.

1 antenna covers 10 square feet

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

Klēone FAQs

Frequently Asked Questions

When will my order arrive?
Orders are usually processed within 1–3 business days, or up to 5 business days during busy periods. Estimated delivery takes 5–10 calendar days after shipment. US shipping is free, and your tracking number is emailed as soon as your order ships.
Is it too late to plant one this year?
No. It can go in at any time of year, in any season. Planted now, it sits in the soil through the winter and is already in place when spring comes; planted in spring or summer, it starts the day it goes in. If your ground is frozen solid, start one in a large pot indoors and move it out at the first thaw.
How many do I need?
One covers about 10 square feet. A 4×8 bed takes four, a large pot takes one, and twelve covers a whole backyard garden.
Can I use it for houseplants and pots?
Yes. You can use it indoors as well as out: one covers a large pot or a cluster of houseplants.
Can I use it on my lawn?
It’s made for beds, pots, planters and trees, where one covers about 10 square feet. A whole lawn would take a great many.
How do I plant it?
Push it about 4 inches into the soil near your plants. In a bed, space them about 3 feet apart. Leave them in all year; there’s nothing to plug in or refill.
What is it made of, and how big is it?
99.9% pure copper, stake to coil, with no plating. It stands about 12 inches above the soil once planted. Outdoors it darkens to a bronze patina, which is what copper does.
How do I get the free eBook and guide?
They arrive by email after you order. If you can’t find them, email support@kleone-copper.com and we’ll send them again.
When will I see a difference?
A garden moves by seasons, so judge it by seasons. Put it in one bed and leave the bed beside it alone. Next summer, trust your own eyes. You have a full year either way.
What if it’s not for me?
Send it back any time within 365 days of delivery for a full refund, no questions asked. Email support@kleone-copper.com with your order number.
