Advanced guide to hydroponics - James Sholto Douglas

Hydroponics is the science of growing plants without using soil; the plant is established in some form of matrix (anything from gravel to plastic) and fed using nutrient solutions and water. This book studies the subject in detail. It is a companion volume to James Sholto Douglas’ earlier Beginner’s Guide to Hydroponics.

The design and construction of many different types of hydroponic units are described. The practical operation and control of the cultures are also explained. Many types of nutrient solutions are examined, the various formulae being analysed in great detail.

The practical management of hydroponics and the economics of establishing and running units are also discussed in depth.

This book should prove to be most valuable to agriculturalists and horticulturalists worldwide. Any overcrowded country or area of adverse climate is a potential area for hydroponic cultivation. James Sholto Douglas’ years of experience in setting up and running hydroponic units should prove of great value to all workers in this field.
