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.
