This book is so badly written, in terms of organization and use of the language as to be incomprehensible in parts. " What if my greens start to ruin? There are two essential reasons why ruin can transform into an issue." Ruin and issue? I would think that an issue can become a "ruin". "In the glow of mid-year, we generally speak water once immediately at the start of the day and a short time later again around evening time." (Page 68) My water never talks back. And dawn and dusk are generally about 12 hours apart, not a "short time". "Chickpea is one...you don't generally need to save them for the power outage." (Page 41) It is repetitious, badly written, lacks information, provides contradictory information -- arugula is very difficult to grow vs. arugula is very easy to grow. No sources are cited. No suggestions about where to buy supplies. Don't waste your money.
