This could be considered a fairly accurate definition of the term
"hydroponics." In its more advanced stages, hydroponics can be a
complex art indeed, but the purpose of this book is to describe a series of
methods that will make hydroponics work for you. It will describe how
to make or where to buy a hydroponic system, how to plant it, how to
maintain it, how to correct common problems, and where to get
supplies. Two of the greatest benefits of hydroponic gardening are the
freshness and high nutritional value of the vegetables and herbs that
can be grown. For these reasons, you will also find recipes from famous
chefs who use hydroponically grown produce in their own kitchens.
What this book will not do is give a lengthy history of the subject,
or a great many personal anecdotes that do little good in helping you get
results from hydroponics. Presumably, results are the reason you bought
this book. By following the procedures listed here you will be able, for
example, to raise several crops of garden vegetables per year at a fraction
of their supermarket cost.
