I started lettuce and spinach seeds on 3/20/11- 8 days ago. They're in peat pods, covered, and receiving bottom heat 24/7; ambient temp in the chamber is approx. 72 deg. Last year, with the same set up, they sprouted in just a couple of days. I'm guessing these aren't going to sprout and I should try again? Is it possible to pre-sprout seeds that are that tiny?
Broccoli, cauliflower, a few tomato varieties and bell peppers in the same chamber have already popped up, if that tells you anything.
