The UrbiPod Basic model is the same as the standard UrbiPod without the growing light and power adapter. It's perfect for areas of the house that already get plenty of natural sunlight, or for putting outside.
The UrbiPod Basic still features all of the self watering and wicking system used in the other UrbiPod models, meaning you can still set and forget and wait for the UrbiPod to let you know when it needs refilling.
Alternatively, maybe you recently upgraded your grow light and now have a spare laying around. Your old grow light still functions perfectly well, so why not whack that on your the UrbiPod Basic model and now you're away and growing with two fully functional UrbiPods.
