Hey Randy,

Height doesn’t necessarily correlate to health, example if the plant is leggy then it’ll be tall but not healthy.

I might look at percentage of germination rate, time to germinate, size of leaves, and maybe color. Color can be tricky, so you might look at creating a color chart to put a numeric value to color.

You’ll always get 2 leaves initially…well, if you have dicot seeds, lettuce is dicots. You could also look at time till true leaves emerge.

Hope this helps.
