They will get bigger faster with the HID light. I start my seedling under HID light. I just have the light a long ways above them until they get theyre second full set of leaves. Then I bring the light down to about 18" from the tops and the veg is on. LOL

I wouldn't let them veg under CFL's if you have an HID available.
