This book is very condensed. It is a small book with short concise paragraphs but is very informative. While the information it contains is very broad, it doesn't go into much depth. It even has some basic information on plant anatomy and some functions. The pictures and diagrams are very good and relate to the paragraphs with corresponding numbers which are easy to follow, just don't confuse the numbers for steps in a procedure. Overall I believe this is a great book for someone who is thinking of beginning hydroponics but I don't think it will be your one source if you're wanting to take hydroponics serious. I give it 5 stars because it lives upto its title "Hydroponic Basics" with basic being very true.
