The seminal 1978 book Hydroponics: Growing Plants Without Soil by Dudley Harris (published in London by Sphere Books) is an authoritative, highly practical handbook. It breaks down how to grow crops, flowers, and vegetables in water-based nutrient solutions rather than traditional soil. 

The book details essential components of soil-less agriculture that remain fundamental today:

• Nutrient Solutions: Detailed recipes and instructions on mixing macro- and micro-nutrients, including nitrogen (N), phosphorus (P), and potassium (K), dissolved in water to feed plant roots directly. 
• Growing Media: Options for aggregate substrates such as vermiculite, perlite, or gravel to provide root support. 
• System Designs: Practical, easy-to-follow instructions on setting up various hydroponic units, ranging from simple drip feeds and wick systems to more advanced water culture techniques. 
• Crop Management: Specific care requirements for sowing, preventing and managing pests and diseases, and adjusting for local climate zones. 

By eliminating soil, this technique allows growers to precisely control nutrient intake, accelerate plant growth, and drastically reduce water usage compared to conventional farming. 

NOTE: This is an original  book from the library gathered by the famous Cambridge Don, computer scientist, food and wine connoisseur, Jack Arnold LANG. Note: Jack founded the Michelin Guide ‘Midsummer House’- Cambridge’s paramount restaurant. This dining experience is hidden amongst the grassy pastures and grazing cattle of Midsummer Common and perched on the banks of the River Cam. 

In 2008, Jack was one of the co-founders of the Raspberry Pi Foundation, alongside other members of the Department, and acted as the Foundation’s Chair. The project’s original goals were modest: to build and distribute low-cost computers for prospective applicants to our Computer Science degree. Initially the project was a “success disaster”, as Jack would say, as demand far outstripped the low-scale manufacturing plans. Ultimately the Raspberry Pi became the UK’s most successful computer with more than 60 million sold to date. Jack was drawn to the educational possibilities of the Raspberry Pi, its potential uses in emerging economies and the way it could support self-directed learning.
