Hypothesis
Different lighting regimes and spectral qualities may distinctly influence the growth, photosynthesis, and biomass production of lentils cultivated in vertical farming systems.
Conclusion
Constant lighting regimes, especially under red, white, and RBW lights, significantly increase biomass production, while Gaussian regimes enhance the accumulation of bioactive compounds like carotenoids.
Supporting Evidence
- Constant lighting under red light significantly increases biomass production.
- Gaussian lighting promotes higher carotenoid accumulation.
- Different light spectra affect chlorophyll content and photosynthetic efficiency.
- Tailored lighting strategies can enhance productivity and nutritional quality.
- Red light improves energy efficiency in biomass production.
Takeaway
This study shows that the type of light used can help lentil microgreens grow better or become healthier, depending on what you want to achieve.
Methodology
The experiment used a 2x4 factorial design with two lighting regimes (Constant and Gaussian) and four spectral qualities (white, blue, red, and RBW), with six repetitions.
Limitations
The study primarily focused on lentil microgreens, and results may not be generalizable to other plant species.
