When to introduce light (rockwool germination)?

(I had already posted this, but it looks like it magically dissapeared?? It wasn't in the Newbie forum and it wasn't showing up in my thread history...so not sure...)

3/4 kandy kush (and both freebies) have sprouted and I can see the cotyledon leaves.

They don't have true leaves yet... Can I give them light or should I wait until they show the first set of true leaves before trying to start photosynthesis? (I've seen plenty of references to both...one of them is already about 2-2.5" tall...)

Germination was started 3.5 days ago and they were transferred to rockwool 2.5 days ago... They are still under a humidity dome also. I'm thinking about giving them some CFL light today, but wanted to make sure that's the best thing to do.

+rep for answers :).
