The Effect of LED Lighting on Hydroponic Farming Systems

A recent study has introduced an innovative hydroponic system aimed at enhancing the growth of carrot taproots by optimizing light exposure without submerging the roots in water. Root crops, which naturally develop in soil shielded from light, face challenges in hydroponic environments that inhibit taproot enlargement. This research utilized LEDs emitting blue, green, and red light to investigate their effects on pigment accumulation in carrot taproots. Results showed that blue light stimulated anthocyanin production and chlorophyll synthesis in outer tissues, while green and red light primarily increased chlorophyll in the stele, with red light showing the strongest effect. These findings provide valuable insights into how controlled lighting can influence root crop development, offering a promising strategy for improving hydroponic cultivation methods. The full study is available on Research Gate and published in the Engineering journal.
