We just got our lighting unit and have started our internal testing. We have observed that microgreen growing can be done with relatively low levels of growing lights. We have also found that the red/blue LED's or high K whites can produce great results. We are using a 16hr light cycle in our application. These inexpensive lights provide enough lighting to grow out nice crops microgreens in a normal amount of time. The color mix works to create healthy and vibrant products. Problem is the light bar providing a horizontal "point" source of lights so the plants will tend to bend to the middle of the trays. You can counteract this by rotating the trays themselves, but it should be enough to harden the crops by finishing under a more diffuse light or sunlight. You can find these in our curated Amazon store where we have highlighted two inexpensive LED light units that work well. Each unit will provide enough light to grow at least 16 our our trays and 32 if you rotate them out. The trick is to manage the height of the light to allow for enough spread to cover your crops. Pictured is our 2ft test unit that fit our space better, but for actual production the 4ft units in our store are more optimal.
