Okay, yeah I remember telling you to raise them now. You want them as close as you can get them without burning up your plants. When they start stretching, they could jump up 1-2 inches overnight, so you want to account for that as well. So as close as you can get them and have a couple of inches for them to stretch. Ya dig? Just use common sense, and you'll be fine. They aren't going to chase the light if you raise them up more. All you will be doing is robbing the lower stuff of light.
