Yes, carrots can be grown indoors, but they are not well suited for most smart gardens or small indoor systems. Carrots need deep soil and space for their roots to develop properly, which many indoor setups cannot provide.
Smart gardens are designed for shallow-root plants like herbs and leafy greens. Because carrots grow downward rather than upward, they often become short, misshapen, or fail to develop fully in compact hydroponic or countertop systems.
Some people do have success growing carrots indoors on windowsills or balconies, especially when using deep containers and loose soil. Short or round carrot varieties work better than long types, and strong natural light is important for healthy growth.
To be successful indoors, carrots need enough depth for roots, consistent moisture, and patience, since they grow more slowly than herbs. Without these conditions, carrots may sprout but never fully mature.
In everyday indoor use, carrots are possible but impractical compared to vegetables that naturally grow compactly above the soil.
