Romaine sprouts (in the tiny seed plugs) and alphalfa sprouts (in the jar) reach toward the hydroponic system's grow lights resting on my dresser. They are four days old. With the grow lights turning on at 5:30am and shining directly into my eyes, I had to put up some light barriers. Those oven liners keep the light and the heat in. Now I can sleep until 6:30.
