One thing I hadn't seen mentioned in any of the threads on seeds/seedlings was them growing upside down. I've had 3 that did this...never seen a seed that didn't know which way was up before Is this normal for adeniums? I've turned them right side up, one might have a very strange caudex as I didn't notice it soon enough and it has curled.
You can see it in the bottom edge middle of the tray. He's actually still upsidedown in the image...I noticed it just after taking the photo
