Starting my tomatoes in bigger pots was a good idea because they are certainly happy. Perhaps next year I need to wait a few weeks longer before I start them as they are out of room! I removed the middle shelf from the lightstand as it was thankfully still empty (procrastination pays off for once) and place it on top of the fully lowered lowest light. Now the tomatoes have plenty of growing room and the middle light has long enough chains that it can go low enough to provide them plenty of light.
