Your Farmstand is easy to expand. This Extension Kit provides additional ports to increase your growing capacity.
We recommend a Single Extension Kit if you have a Medium (30 Plant) Farmstand or smaller. Generally, you should have no more than 6 levels (36 Plants) for optimal growth, stability, and performance.
