Course: Sanitation & Sterilization in Hydroponics
Section 1: The Biology of Sterility
Lesson 1: The Science of Oxidation
Welcome to The Biology of Sterility, a deep dive into maintaining a pristine aquatic environment for your crops. In recirculating hydroponic systems, the water is a living ecosystem that can quickly shift from a life-giving resource to a breeding ground for pathogens. This lesson focuses on the proactive use of oxidative chemistry to dismantle biofilms, eradicate microbial loads, and keep root zones vibrant and healthy.
Identify how microbial loads accumulate and the risks they pose to recirculating systems.
Explain the chemical mechanisms of oxidation and hydroxyl radical cellular lysis.
Analyze the impact of biofilm on dissolved oxygen levels and nutrient uptake.
Calculate and interpret the chemical breakdown of H2O2 into water and free oxygen.
Monitor system health using ORP and DO meters.
Assess the boundaries of safe oxidation to prevent root damage.

Defining the Oxidative Process
DefinitionsBreaking down oxidation, hydroxyl radicals, and cellular lysis.
The Cost of Biofilm
Pain PointsHow slime layers protect pathogens and crash dissolved oxygen levels.
The Chemistry of Breakdown
EngineThe chemical reaction: 2H2O2 → 2H2O + O2 and the release of free oxygen.
