How many Extension Kits can I add to my garden bed?

The possibilities are almost endless when adding length to your garden. We've had customers create gardens well over 20 feet (we recommend not going beyond 3.5' in width, when extending the length of your garden).

Modular

Each garden kit comes with multiple panels for complete autonomy of your dream garden set-up. The modular design gives you endless configurations when buying multiple sets.

Sustainable

The steel is 100% recyclable and made using a green manufacturing process.

Longevity

The thick (0.6mm) specially coated steel is what sets us apart. Your garden kit is designed to last 3-7x longer than regular galvanized steel and has a lifespan up to 20 years.

Safe for Veggies

Our specially designed steel provides safe gardening for all your vegetables. With typical soil acidity levels hovering around neutral, there should be no concern with leaching metals into your soil.

Safe for kids

Commercial grade rubber lines the top of the garden providing a comfortable place to rest arms and hands on, while also making it safe for kids.

Comfortable Roots

Take control of your soil health with up to 32” of fresh fertile earth. The generous depth provides ample room for strong roots and healthy plants.

Unmatched Durability

Sproutbox beds are built from Magnesium-Aluzinc Steel, lasting 3-7x longer than wood and standard galvanized steel. While the initial investment might be higher, the savings over time are significant. Invest once, enjoy for decades—it’s that simple.

Premium Quality

Sproutbox beds combine commercial-grade durability with a design that’s been backyard-tested and gardener-approved. While other options may seem cheaper upfront, they often lack the same longevity and ease of use. With Sproutbox, you’re investing in a hassle-free gardening setup built for real gardeners.

Ergonomic Design

The height is perfect for a comfortable gardening experience. No more deep bending—just plant, tend, and harvest with ease. This extra height also supports deeper root growth, which means healthier plants and better yields.
