Here are my seedlings so far. They are flanked at the bottom by begonias, that are slowly coming out of their winter hibernation. I have these shelves in my warmest upstairs room (although I'd eventually like to have them in the basement, in a grow tent.)
I've repotted the tomato, red pepper and eggplant seedlings into 2" containers (re-used from garden store plants I've bought.) I fear it's a little too big of a jump, but hopefully the eggshell surrounding the roots (I just crushed the shells a little to let the roots spread) will be a bit of a buffer. So far they're doing well, with a new set of leaves on most seedlings this week!
