Hydroponics is a type of horticulture and a subset of hydroculture that involves growing plants (usual crops) without soil, by using mineral nutrient solutions in an aqueous solvent. This book is an instruction manual different from anything else out there. If you're looking for detail on growing near-perfect microgreens that are simple to grow, extremely clean, and easily repeatable, with huge harvests often doubling or tripling standard fare, then this book is for you. This is filled with tons of information including disease prevention, fighting fungus, organic techniques, maximizing harvests, recipes, troubleshooting, hoards of pictures, and commercial options including packaging and increasing scale.
