Propagation: Flower seeds and germination "situation", 2 by BigZig

Ok - that makes sense. The only flower that I can't wrap my head around with that concept are the Nasturtium. I have 100% germination with the six(6) that I sowed, and within two(2) days they were pushing up against the top of the plastic dome of the seed starter. The two(2) initial leaves were dime sized (much, much larger than everything else that has started).

On day 6 (from sow), I opted to pull the first two(2) Nasturtium seedlings and move them to a peat pot without a dome so they wouldn't be limited in their height growth.
Was this too early to move this seedling?
Do I need to be concerned with head height of seedlings?

This is also the day I made my first, possibly fatal, error. I will not be using the Jiffy seed starting wafers again; I ended up shearing off the root sprout right at the seed trying to remove everything from the planter cell. I went ahead and moved this less than one week old seedling to a potting soil mix/peat planter anyway. Today, day 7, that plant has begun pushing a second set of leaves.
Note of interest: a second plant that was transplanted had 3.75" of root pushed outside the mesh that those Jiffy wafers use. I sliced open the mesh up to the root, but was unable to free the root due to fear of damage (I already seperated one very healthy root from a perfectly good seeding). I'm going to wait a week before I transplant anymore to make certain they will take in the richer soil - I have three(3) more plants already pushing against the plastic dome.
