100% germination
Off to a good start! It always pays to be patient with seeds and give them a chance as some of them can take their time.
The tallest seedling looks to be stretching a little so you could lower the light a bit to prevent it getting too lanky. Not too close though, as you don't want to burn it, so lower it a couple of inches and then keep your eye on the seedling and the temps. If the seedling stretches again afterwards, repeat the process.
