Upland cress is one of the most nutrient dense microgreens to be found. Microgreens by their nature are superior to the mature plant matter because of the exceptional concentration or nutrient density within the small structure of the microgreen. You can obtain anywhere from 4 to 40 times the nutrient value by using these amazing plants.
Earlier information led us to coloration as one of the markers for powerful compounds called anthocyanins that have shown positive effects on cardio vascular disease, cancer and can boost brain function. Further research has shown that you can enhance compounds in plants by exposing them to different wavelengths of light. We noted the effect of blue LED lights had on the tested vegetables.
We attempted to see if we could duplicate these results on our simple microgreen system here. Again, the last blog highlighted growing out our upland cress microgreens so we built a grow bench that provided our blue LED lighting to grow out our microgreens. The photos here show the results of growing out our cress for a six week period and using the blue lighting for the last two weeks on the tray on the right side. Notice the enhanced purplish color of the right tray. I do believe now that a final finishing grow under blue LEDs should enhance the nutritional compounds available in our microgreens.
