People have always grown microgreens using soil for several years. But now, the hydroponic microgreen growing method is popular. Hydroponics can help solve problems without excessive use of space or water, are known to produce vegetables with high nutrient content, and produce vegetables faster than traditional growing methods. Its the technique of growing plants using a water-based nutrient solution rather than soil and can include an aggregate substrate, or growing media, such as hemp fiber, coconut fibers, or rock wool.

It has no pathogenic bacteria, toxic and harmful substances. It provides a pollution-free root environment for growing green crops.
