Sensitive Plants: When to remove the lid?

[radlations]

So I've been growing sensitive plants. I planted about 10 seeds. It's been 5 days and so far, I've noticed at least 3 have germinated.

I was wondering if I should take the lid off now, or leave it on until the rest germinate.

I'll need a littel more description here, what is a sensitive plant? Do you have names for your plants?

I keep the lid on my seedlings until they are touching it and it is interfering with their growth. From there, I take a plastic bag (clear) and put that over each seedling. It creates a sort of greenhouse, keeps moisture in, and the plants just do so much better that way.
