BY FOLLOWING THE INSTRUCTIONS IN THIS BOOK, YOU WILL BECOME THE MANUFACTURER OF AN IDEA. THIS BOOK IS AN INSTRUCTION MANUAL FOR A PRODUCT THAT ONLY EXISTS IF YOU BUILD IT. HERE ARE THE INSTRUCTIONS. I HAVE DESIGNED THIS DEVICE SO THAT YOU CAN PRODUCE YOUR OWN FOOD AT HOME OR IN YOUR OFFICE, USING SOME INEXPENSIVE IKEA BOXES AND THE DIRECTIONS IN THIS BOOK. THIS SYSTEM USES HYDROPONICS, A FARMING TECHNIQUE THAT CAN BE USED TO GROW PLANTS IN WATER INSTEAD OF SOIL. THE REASON FOR USING HYDROPONICS IS VERY SIMPLE: HYDROPONICS ALLOWS YOU TO SAVE UP TO THE 90% OF THE WATER USED IN A TRADITIONAL AGRICULTURE SYSTEMS, REQUIRES MUCH LESS SPACE, AND PROVIDES YOU FULL CONTROL ON THE NUTRIENTS REQUIRED BY THE PLANTS AT ALL STAGES OF THEIR GROWTH. ANOTHER GREAT THING ABOUT HYDROPONICS IS THAT YOU DON'T HAVE TO WORRY ABOUT WATERING THE PLANTS. THE SYSTEM I HAVE DESIGNED COMBINES DIFFERENT HYDROPONICS TECHNIQUES. THESE ARE ADAPTED TO MAKE THEM EASY TO USE AT HOME, TURNING YOU INTO A FARMER, PERHAPS AN URBAN FARMER. HOWEVER THIS BOOK IS NOT A BOOK ON URBAN FARMING, NOR IS IT A GENERAL BOOK ABOUT HYDROPONICS. THIS BOOK IS A MANUAL THAT WILL SHOW YOU HOW TO BUILD AND RUN A SIMPLE HYDROPONIC SYSTEM WITH SOME INEXPENSIVE IKEA BOXES. I CALL THIS SYSTEM ELIOOO.
