This is a light stand I made for a hydroponic setup in our spare bedroom:
I live in urban Tempe, AZ. While going rural is a lingering ambition for many of my friends and neighbors, I think the principles of permaculture can still apply to an urban lifestyle. Here in Arizona, our power company is investing in renewable resources and "greening the grid" as many power companies are. How do you feel about an on-the-grid alternative to fuel-dependent farming and distribution? I don't like to think that those of us who don't have land are out of luck. It's working for us, and many people in our city are producing food on small lots because we get lots of sunshine. We don't even need to refrigerate the produce we grow at home because we harvest as we eat.
The other obvious advantage to growing indoors is climate control. While our toughest plants are scraping by in the heat, our delicate plants are as comfortable as we are inside.
I'm curious if this presents a challenge to the values of permaculture, or if hydroponics is a step in the right direction for urbanites.
