How to Supercharge Your Garden by G. Reinders/Marseene Mainly
A well-presented handbook with simple but not simplistic guidance over every aspect of indoor cultivation with lights and hydroponics. Especially focuses on high yield production and high dry matter in the harvest, claiming 60% more dry matter in every kilo of undried product from their method, including more vitamins, sugars and minerals because there is less water. Lots of tables and schematics to show how things fit together. 168 pages.
