I noticed these two guys in my seed tray yesterday. I guess they must be a couple weeks old, since they already have a true leaf.
I also have a question. I've read that they need cool temps on their roots. If the day temp reaches 79 F (26 C), and the night temp reaches 69 F (20-21 C), will they do fine? I still try to water them with cold water overhead every now and then.
