It was cool to spot this Tower Garden (2 of them, in fact) in the cafeteria of Stephens College on a recent visit to Columbia, Missouri for the Citizen Jane Film Festival.
I have seen a variety of these systems, but this is my first experience with Tower Garden specifically. I did a little research on the device and the company and included it in the links below.
This unit is a bit expensive for most individuals, but there are a host of others available and a wide variety of DIY systems available on the internet. Take a look!
