Hydroponics - Indoor Horticulture represents an educational, in-depth, up-to-date, indoor horticultural growers guide that covers all principles of indoor hydroponic horticulture and gardening. This book contains 110,000 words, with over 300 diagrams, pictures, illustrations, graphs, tables, 3 dimensional CAD renderings, and is printed in full colour.

Hydroponics - Indoor Horticulture examines, explores, dissects and presents a fully comprehensive step by step growers guide, relating to all and every aspect of indoor hydroponic horticulture, with complete chapters on plant biology, propagation, hydroponic systems, nutrients, oxygen, carbon dioxide enrichment, pH, biological pest control, fungi/disease, cuttings/clones, pruning/training, breeding, harvesting, equipment, grow rooms, a full history of hydroponics, and more.

This book goes further than any indoor growers guide has gone before, presented in full colour with 3 dimensional CAD renderings.

In terms of literal content, quantity, quality and presentation, no other indoor horticulture growers guide can compete, let alone compare.

One word of warning: the temperature of your water affects the reading of your digital pH meter. A story springs to mind where a grower, for the life of him, was not getting the performance he should have been, as the plants were in a constant state of ill health, pale in colour, no vigour and very slow in growing. After hours of cross-questioning him on all levels of running his grow room and feeding his plants and so on and so forth, at the end of the conversation as a passing note when he was leaving, he made comment that “oh, by the way, I always add a kettle of boiling water into the reservoir after filling it up.” He delivered this statement as if every grower in the world followed this practice. So I then asked him “ I take it you then balance your CF and pH after this?” Here was his blinding mistake. Directly after administrating boiling hot water to the reservoir he would adjust his CF and pH and in so doing, the reservoir having had a volume of very hot water inside it, therefore gave CF and the pH readings that were completely wrong. He would have been better off guessing rather than measuring it with his meters, as the volume of hot water changes the pH reading on your digital meters dramatically and also, but not to the same level, it affects the CF readings too. After showing him the error of his ways, the plants soon picked up and the grow was a good one.

Hard or Soft Water

To know what type of water you are using when using a hydroponics technique is fundamental to the upkeep of your system. So the type of water you have is an important factor when considering what nutrient solution to purchase.
