Humidity Dome Seedlings and clones

i have 5 seedlings and two clones in my dome. The seedlings have sprouted and may be kinda stretching, so i feel like they could maybe come out. But, the two clones might not be ready, and i don't have the room to take the seedlings out and leave the clones.

What should i do?

When is a good time to take the dome off seedlings? clones?

As for the clones make sure they are fully rooted with roots popping out everywhere.. as for the seeds, I wait until they have leaves growing.... Can you move your light closer to slow down the stretch? Peace

Okay the clones are in snack pack cups so ill be able to see when roots are on the side.

The first pair of true leaves are coming on 4 out the 5 seedlings and the tallest one is about 4", and another is not far below it. luckily i have one that must just be in a really good light spot and its like two inches.

Im using CFLs by the way and because they're in the dome the lights are kinda a good distance from the plants. the only way i could get them closer would be to move them to a 1/2 an inch away from the dome. I would think it might melt the plastic.
