The "Pepper-in-a-Can" System | Universal Planter & Drip Tray

The Pepper in a Can Challenge is a classic test of indoor gardening - growing a productive pepper plant in the limited root space of a soda or beer can. It’s perfect for winter growing, but cans are notoriously unstable, prone to leaking, and (let’s face it) usually have distracting graphics.

I designed this sleeve to turn a recycled can into a professional-looking desktop planter. My test Habanero is currently thriving in a 16oz can, and these sleeves have kept the setup clean and tip-proof even as the plant becomes top-heavy with fruit.

Why use this sleeve?

• Stealth Aesthetics: Covers bright logos for a uniform, minimalist look.

• Anti-Tip Base: The integrated tray widens the footprint, preventing your plant from falling over when the soil dries out.

• Smart Drainage: Designed to work with side-punched drainage holes to manage runoff without a mess.

Compatibility & Sizing

How to Use

1. Prep the Can: Remove the lid of your soda can with a can opener. Then poke four drainage holes around the base of your can, roughly 1cm from the bottom.

2. Insert: Slide the can into the printed sleeve.

3. Align: Ensure your punched holes align with the drainage cutouts at the base of the sleeve.

4. Grow: Fill with a high-quality potting mix and start your challenge!
