all 3 of these popped. the WW popped really fast and had the longest tap root. Probably about 1/2" - 3/4" long. It already curled over and looks like it wants to pop open completely.

I placed all 3 into rapid rooters and covered the tops of their holes with coco. I used some plastic knives to label them.

These are all feminized seeds btw; not sure if I mentioned that.
