- Mixing nutrient solutions and measuring tools
- Water quality testing and adjustments

Lesson 6: Environmental Controls
- Light requirements: spectrum, intensity, photoperiod

- Market demand considerations

Lesson 8: Integrated Pest Management & Troubleshooting
- Common pests in indoor systems: aphids, thrips, fungus gnats
- Preventive strategies and beneficial insects
- Disease identification: root rot, powdery mildew, damping off
- Nutrient deficiency diagnosis and solutions

This topic will include laboratory activities and scheduled production. Timely attendance and completion of assigned tasks are required of all students. Activities may focus on microgreens or mixed leafy green vegetables depending on availability of equipment and local interest. Due to low cost of entry, the usual laboratory environment consists of a mix of microgreens "racks"and small tower gardens, though other modalities may be present.

Lesson 9: Safety & Lab Protocols

- Creating optimal germination environments
- Transplanting seedlings to hydroponic systems
- Clone propagation and plant maintenance

Lesson 13: Daily Operations & Maintenance
- Daily, weekly, and monthly maintenance routines
- Monitoring and adjusting pH and EC
- Reservoir changes and system cleaning
- Plant training and pruning techniques

Lesson 14: Data Collection & Analysis
- What to measure: growth rates, yields, resource inputs
- Creating production logs and tracking systems
- Using data to optimize production
- Introduction to sensors and automation tools

Lesson 15: Harvest & Post-Harvest Handling
- Determining harvest timing and maturity indicators
- Proper harvesting techniques to maximize shelf life
- Washing, drying, and packaging procedures
- Storage conditions and food safety compliance

Lesson 16: Scaling Systems & Production Planning
- Transitioning from hobby to commercial scale
- Production scheduling for continuous harvests
- Labor requirements and workflow optimization
- Case studies of successful small-scale operations

Lesson 17: Energy & Resource Efficiency
- Calculating electricity costs and consumption
- Water usage and recirculation strategies
- Reducing operational costs through efficiency
- Renewable energy integration possibilities

Lesson 18: Troubleshooting & Problem-Solving Workshop
- Diagnosing real production problems (case studies)
- Emergency response protocols
- System failures and backup planning
- Learning from mistakes: common pitfalls

Depending on the institutional context, this topic is often taught as a sequel to Topics 1 & 2 and may have additional enrollment requirements, specifically familiarity or experience with business planning and operations.
