I'm once again having problems with leggy little seedlings, so went searching around and found this information about starting seeds. Near the end of the answers is the reminder:
"Finally, be sure to keep your fluorescent lights no higher than 3” above the seedlings at all times."
Welcome to read this about Caring for Seedlings: http://en.allexperts.com/q/Seeding-Propagation-733/Caring-seedlings.htm, too. I've bookmarked it for refreshing my own memory later :)
