What you'll learn:
- How aquaponics works and why it can outperform hydroponics for cannabis: closed-loop water, nutrient cycling, and beneficial microbes.
- The sustainability gains: 90–95% water recirculation, reduced synthetic fertilizers, and lower energy/resource footprint.
- Commercial and regulatory implications: why unique cultivation methods create supply-chain advantages and differentiation for medical cannabis.
- Lessons for founders and investors: the power of deep R&D, place-based innovation (Nova Scotia), and vertical integration strategies.
