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.
With the exception of a cursory knowledge of how hydroponics came about, most readers couldn’t care less about the long list of people who have experimented with hydroponics, or when. Nor do most readers care that some nutrients can be “locked in” under certain conditions and are therefore unavailable to the plant. These things can be found in the books listed in the bibliography. Here we will be dealing with only some of the hundreds of formulae where all the nutrients are available to the plant. In other words, I will not be giving you a lot of superfluous scientific information. If anyone feels that I haven’t given enough background or scientific information, then they’ll have to consult other books, because Hydroponics for the Home Gardener is written expressly to give you the facts you need.
