Marigold seedlings

At this point, the marigold seedlings under both kinds of lights have their first real leaves. The leaves are a bit larger under the fluorescent lights. The radish seedlings in both trays are leggy looking and the arugula has not sprouted, in spite of the fact that I thought I saw seeds swelling and tips of green showing. On the top is the tray under the fluorescent lights and on the bottom is the tray under the LED lights.
