Thanks for the replies and the ruler Indy
Since I was really impatient, I did start a 20 cell tray of, what I hope is, frost tolerant veggies (x4 Broccoli: Major Hybrid & Strawberry Spinach, x2 Broccoli: Romanesco, Swiss Chard, Cabbage: White, Cabbage: Jersey Wakefield, Pak Choi, and Florence Fennel) so I can chuck them out early.
And I just might try gixx's snow seed suggestion - last frost isn't till April 20th and the snow should be gone in a week or two, enough time for some quickies.
I am planning (note: hoping) to grow a little bit of everything. Inside, I really want to get a jump start on some tomatoes, cucumbers, peppers, and squashes. Last year, I put out some small seedlings and the snails got them - proper transplants should survive them, right

?
The only places inside that I can keep the plants are on top of the fridge were I jerry-rigged a grow light and the angled ceiling is one to two away. And on two 2 ft x 4(?) in windowsills (south & west facing). The windowsills are the double window kind, so it has an exterior window/screen and interior window; the interior window would have to be closed because I have three young and curious cats. And hence, the worry about size.
