Cannabis Irrigation and Fertigation Systems. A Practical Guide to Water Quality, Feeding Management, Substrates, and Nutrient Delivery - Alice Schwartz;Drayden Moss

Efficient irrigation and fertigation are central to consistent cannabis cultivation. From water quality and substrate selection to feeding management and nutrient delivery, growers need systems that are structured, measurable, and repeatable.

Cannabis Irrigation and Fertigation Systems provides a practical framework for understanding how water, nutrients, substrates, and delivery systems interact in modern cannabis production. Written for cultivators, grow-room managers, and technical readers, this book explains the core principles behind irrigation design, fertigation planning, runoff management, EC and pH monitoring, and substrate-based feeding strategies.

Inside, readers will learn how irrigation decisions affect root-zone conditions, nutrient availability, plant health, and crop consistency. The book covers key considerations for hand-watering, drip irrigation, recirculating systems, drain-to-waste setups, automated nutrient delivery, reservoir management, and environmental integration.

Designed as a clear technical reference, this guide helps readers build a stronger understanding of cannabis irrigation and fertigation without relying on guesswork or overly simplified advice. Whether used for planning, troubleshooting, or refining an existing cultivation system, it offers a structured approach to managing one of the most important parts of the grow environment.

Topics covered include:

Water quality and filtration considerations
EC, pH, and nutrient concentration management
Feeding schedules and irrigation timing
Runoff measurement and interpretation
Coco, soil, rockwool, and hydroponic substrates
Drip irrigation and automated fertigation systems
Root-zone oxygen, moisture balance, and salt buildup
Reservoir management and nutrient solution stability
Common irrigation mistakes and system troubleshooting

For readers seeking a practical, systems-based understanding of cannabis fertigation, this book provides a grounded foundation for better decision-making in the grow room.
