Soilless Microgreen Cultivation: Scientific Insights from a Simple Hydroponic Cup ExperimentUrban agriculture is changing fast, and one of the most exciting innovations in this space is soilless microgreen cultivation. In a recent experiment, I explored how everyday seeds—Fenugreek, Mustard, and Mung—grow in a purely hydroponic setup without any soil, cocopeat, or growing substrate. Using only hydrated seeds, transparent cups, and well-balanced LED lights, the results were surprisingly strong and scientifically compelling.This method demonstrates how anyone can prototype microgreen systems quickly and cleanly—making it perfect for learners, hobbyists, and beginners across India.Why Soilless Microgreens?Traditional microgreens rely on some kind of substrate.
