It’s been a little more than a month since I planted the clementine seed. The sprout has two round leaves and looks very healthy. During the first month it’s been under a weaker grow light with fewer red and blue LEDs. For about a week now, it has been moved to a brighter, red and blue LED grow light set. Now I see a tiny, thin stem getting thicker just above the existing leaves.

Below is a photo of the sprout around the two week mark. This is when I moved it to the aquarium grow lights.
