Marsha! they all look like keepers to me, all very healthy and growing beautifully! If I had to choose, I would select the two on the left just because they are appear to be the most vigorous and sturdy of the group but There really is not much difference and they all will do well I am sure.
What is your prediction as to how many days old they will be when the first bloom opens? My guess is another 2 weeks so around 45 days from sowing.
that might be a little optimistic but I am feeling lucky about these being quite early.
So excited to watch them grow! Awesome job on the seedlings Marsha, they look perfect.
