First seedlings and a temperature check

A few marigold seedlings are up in both trays and I can see both the radish seeds and the arugula seeds beginning to sprout. I'm amazed at how fast the seeds are germinating. At this point, there seems to be more activity in the flat under the fluorescent lights, but the difference is not great.

I just checked the temperature to see what sort of difference there was. The temperature in mid-day at the top of the soil in the flat under the fluorescent lights was 79 degrees, while that in the flat under the LEDs was only 72 degrees. This will certainly make some difference in germination rates.
