Here is a progress shot of the first month of my new Tower Garden.

I live in Mesa Arizona.

I have (from top to bottom) Muir Lettuce, Cherokee Lettuce, Brussel Sprouts & Spinach, Mustard & Onoins, Zucchini & Cherry Tomatoes.

No problems yet with bugs or critters.  We have plenty of rabbits and chipmonks and birds in our backyard, but so far they've stayed away.

I recently posted a question about measuring the need for Nutrients with a TDS meter.  If anyone has insight into that, please respond.
