Here are the spider plants. I think they look bigger, maybe. They have definitely rooted. I found a website that said you can tell if a transplant has rooted by gently tugging it. I tugged, nothing happened, so they are rooted!
Here's the bright green plant. I think it has rooted. At least at each end, but not the middle. The tug trick pulls the middle, where the big leaves are, up but not the two ends. At the tip that was growing has gotten bigger, so that's a good sign right?
