This book differs from most other hydroponics books in that its emphasis is on how to grow specific plant varieties rather than the mechanics of how to set up a hydroponic system. The major systems which have been commercially successful throughout the world are given significant attention, but less popular commercial methods, while mentioned, are not an important part of this book. Detailed information is supplied on 86 different types of vegetables, fruits, cut flowers, herbs and other plants and how to grow them in hydroponics. Throughout the book, emphasis is placed on that which is commercially viable and how to improve your profitability in a cropping situation.
