Add an extra growing Pod to grow more fresh herbs and salads and rotate your Pods in and out of the UrbiPod as they grow and mature. This way you can have the next crop of herbs or salads growing while you are eating the ready to consume ones. And you can have a wider variety of herbs with more Pods. Each Pod includes Urbotanica's clever wicking system - the false floor plate, short wick and the round wick disc. These are essential to successful growing.
