If you’re asking, “How deep are the standard planter boxes from your planter box factory—I need at least 18 inches for root vegetables?” the answer is clear: our standard planter boxes are designed with flexibility in mind. While many of our pre‑made models come in depths of 12, 16, and 18 inches, the 18‑inch depth is a standard option we produce regularly. For root vegetables like carrots, potatoes, beets, and radishes, 18 inches provides ample room for unobstructed root growth, ensuring healthy development and high yields.

At our factory, we understand that every gardener has unique needs. That’s why we offer customization—if you require a specific depth beyond our standard 18‑inch boxes, we can adjust the dimensions to suit your crops. Our 18‑inch planters are built with durable materials such as cedar, recycled composite, or galvanized steel, all designed to withstand weather and prolonged soil moisture.

If you choose a shallower box, say 12 inches, root vegetables may become stunted or deformed due to insufficient soil depth. Therefore, 18 inches is the minimum we recommend for optimal results. Many commercial growers also prefer this depth for broader root systems. To confirm availability or to place a custom order for deeper planters (up to 24 or 30 inches), we encourage you to contact our sales team directly. We can provide exact pricing and lead times based on your volume and dimensions.

In summary: Yes, our standard lineup includes 18‑inch‑deep planter boxes, which perfectly meet your requirement for root vegetables. And if you need even deeper options, our factory can accommodate you. Trust our craftsmanship to deliver boxes that support vigorous, productive crops season after season.
