This book has been written by a team of horticultural scientists and hydroponics experts most with decades of experience; in response to a fundamental question that continually gets asked: "How do I make (or manage) the nutrients?"
Hydroponic or tissue culture nutrition is a complex subject with so many "moveable parts" to the discussion, that no one answer is appropriate to all situations.
If you are to manage plant nutrition in hydroponics, tissue culture or any other "artificial" situation, you need the sort of knowledge found in this book.
Start here, and you will be in a far better place to make decisions about nutrition in any context, as you move forward.
Plants naturally grow in soil, but modern science has found other ways for them to grow.
Once you understand what things soil does for plants, you can then with the help of modern science begin to conceive other ways of doing those things, replacing the need for soil.
The main thing soil does for a plant is to provide nutrients. It also provides a place for the roots to anchor the plant, and an environment to insulate the roots from extreme weather and provide moisture and oxygen for the roots to absorb.
Hydroponics and tissue culture are technologically advanced ways of growing plants without soil. They offer the grower many advantages, not the least an ability to have greater control over how the plant grows.
Pivotal to that control, is to understand and manage the nutrients provided to the plant. This management of nutrients is what this book is about.
