My Seedling Pics--First Timer

[emzybo]

Here are some pics of my general (cluttered) seed starting setup.

This is my first year growing tomatoes from seed, and I'm pretty anxious about keeping them alive, lol. Shown are various stages of tomato and herb seedlings--I'm going to try to plant some out early, and I have backups. (Perhaps I even have backups for my backups as I've heard stated on here before.) I do feel kind of sorry for my poor "guinea-pig" seedlings, but I think many seem to be doing okay. The oldest were planted about 3 1/2 weeks ago, so the seedlings are at most 3 weeks old.

Any constructive advice, comments or ideas are greatly appreciated!
