When I said I wanted the LR2's to stretch a little, what I actually meant was this. They have two sets of leaves, not including the initial two leaves as seedlings. There is little to no gap between the two sets of leaves. So, I'm thinking the lights need to be farther away. I've been able to get the light within 2 inches and keep temps at 78F, so I thought that would be fine. But it seems that they'll be needing a little space from the light(???). Look, I'm all about suggestions, so if you've got one I'll take it.
