I bought more lights for the dandelions and, just now, I went and checked on them. I am happy to report that I did not need the lights. I'm not quite sure what happened between yesterday and today, but they all seem to have made a complete 180 degree turn around. All the droopy leaves perked right up and there were even tiny fourth leaves sprouting on a few of the plants!

It has been raining all day in Philadelphia today and it is supposed to rain all day tomorrow. When it rains dandelion flowers close up.
