The Vertical Farm: Feeding the World in the 21st Century, Dickson Despommier: Despommier is considered the father of vertical farming and this is the book that got many people started in this movement. After reading this, you’ll fantasize about skyscrapers feeding cities and know where to look for further research.
The E-Myth Revisited, Michael Gerber: This is a general business book that demonstrates the importance of implementing replicable systems – something most small farmers avoid that leads to wasting their own labor and often money on bad hiring decisions and inefficient work flow.
The Urban Farmer: Growing Food for Profit on Leased and Borrowed Land, Curtis Stone: While not focused on hydroponic or vertical production, learning how Stone thinks through his farming decisions in terms of maximizing profit and space is beneficial for any farmer.
Vertical Gardening: Grow Up, Not Out, for More Vegetables and Flowers in Much Less Space, Derek Fell: Though this book is meant for gardeners, its principles are easily transferable and people love it. Fell teaches you how to look at intensifying a given space while minimizing effort – the foundation of vertical farming.
Teaming With Nutrients, Jeff Lowenfels: This book makes cellular biology not only readable, but super engaging too. While also written for gardeners, the science Lowenfels explains is absolutely necessary for people working with hydroponics or reliant on nutrient (whether from things like compost tea or synthetics).
