Worldwide, we are experiencing rising food prices and widespread famine. Our current food production model is not sustainable. It contributes to pollution, deforestation, and consumes most of our fresh water supplies. Hydroponics is the future of food production. The good news is that it's a technology that is accessible to everybody. You can easily create a hydroponic system in your backyard or even inside your home or apartment and be able to produce high-quality food at a fraction of the cost. Perfect for those who want to get into small-scale greenhouse farming, such as rooftop- or urban farming, this book covers everything you will need to know about hydroponics, regardless of your level of expertise. Different hydroponic systems (nutrient film technique, wick, drip, aeroponic, water culture, ebb and flow) are explained, along with information on how to set up and care for indoor and outdoor growing environments that includes information about seeds, plant requirements, various growing mediums, light, temperature, nutrients, and pest control. Since we all have busy lives, this book will also explain how to automate virtually everything to minimize your involvement using both commercial and homemade equipment, such as relays, microcontrollers, shift registers, system alarms, humidity sensors, water flow sensors, pH probes, and more. Soon you'll be able to supplement your family's food requirements or even start supplying fresh produce to your neighborhood with your own hydroponic system. And you'll be delighted to know that favorite crops such as tomatoes, salad greens, peas, and peppers thrive in hydroponic conditions.
