Sustainable homegrown microgreens cultivation system for urban environments

Overview

Urban residents often lack access to adequate plot space for cultivating functional gardens, limiting their ability to grow fresh, nutrient-dense food at home. This proposed solution addresses that challenge by developing a sustainable homegrown microgreens system optimized for minimal space and resource use. Microgreens are immature sprouts harvested from seeds and are known for their high concentrations of phytonutrients, macro and micro elements, carotenes, phenolic compounds, and vitamins C, E, and K1. By integrating optimized soil substrates, controlled water delivery, and targeted LED lighting, the system enables consumers to produce highly nutritious microgreens that can be incorporated into salads, soups, smoothies, or as supplements in bread and tortilla flours.

Technical specifications

Key features:

• Substrate optimization: A standardized mixture of peat moss and organic compostable substrate designed to maximize germination rates and growth performance
• LED lighting integration: Use of colored LED lights to positively influence microgreen growth and nutrient development
• Controlled water delivery: Standardized hydration protocols to minimize resource consumption while maximizing yield
• Nutrient validation: Chromatographic analysis to quantify phytonutrient content and confirm nutritional benefits
• Diverse crop range: Cultivation protocols for herbs such as cilantro, basil, and thyme, Brassica genus vegetables, and traditional Mexican ingredients including epazote and achiote not previously characterized as microgreens

Technology readiness level

The project is currently at an early-to-mid stage of laboratory validation. Preliminary laboratory work has already demonstrated that the peat moss and organic substrate mixture positively affects germination and growth, and that colored LED lighting enhances development. The next phase involves standardizing substrate composition and culture conditions to maximize germination, growth, and phytonutrient content over an estimated one-year timeline. The research team is seeking a partner to assist with seed acquisition and provision of analytical standards for chromatographic analysis.
