Indoor hydroponic optimization through tailored nutrient and water management

Overview

This solution addresses a critical challenge in indoor hydroponic farming: the lack of an adequate nutritional management plan that supports healthy plant growth without compromising root systems. By characterizing the full indoor production environment—including substrates, structural supports, LED lighting, humidity, water management, and current productivity—and then experimenting with tailored fertilization schemes for each vegetable variety, the approach delivers a customized Indoor Hydroponic Nutrition Plan. The result is improved foliage quality (color, thickness, leaf size, and count), stronger root development, and higher overall system efficiency and profitability.

Technical specifications

Key features:

• Species-specific nutritional management plans tailored to each vegetable variety cultivated
• Optimization of core physiological processes including respiration, photosynthesis, and transpiration
• Compatibility with LED-assisted indoor systems, accounting for variations between artificial and natural light photosynthesis
• Characterization of substrates, physical supports, LED lighting parameters, artificial light management, water usage, and environmental humidity
• Evaluation of fertilization schemes from both agronomic and economic perspectives, maximizing cost-to-benefit ratios
• Improved root system health as a central design consideration

Technology readiness level

The solution is currently at an early-to-mid research and validation stage. Initial tests with standard fertigation fertilizers have been completed, but an adequate management plan has not yet been defined. Future work involves systematic experimentation with multiple fertilization schemes for each planted variety, followed by profitability analysis. The technology is ready for pilot implementation within the existing indoor hydroponic production system.
