They should be fine where they are. Just keep an eye on your plants and if they start stretching out then just lower them a lilWondering how close I should keep my two 42W cfl's from my 2 week old from seed plant? I have them on a y adapter. They are about 1 3/4"-2" away and it doesn't seem very hot at the leaves. Should this be OK it seems to be growing well in a small party cup so far.
