I did start off with two seeds.
I'm not sure whether curiosity or impatience drove me to examine the soil more closely. Upon investigation, I discovered the tap root had grown sideways, and with a bit more patience, the plant might have been viable.
*** I forgot to moisten the medium (Pro-Mix HP / Worm Castings ) inside the cup , perhaps this is why the root had issues ? Wish I could of taken a picture , It was headed the long way....
