Growing lettuce in a box? Plastic cover at first?

In order to grow lettuce in my urban garden near the commuter rail line, I made a bottomless box (i.e., 4 pieces of 1"x8" set on their long edges and screwed together to make a rectangle about 18"x30") and set it on my raised bed garden of older soil, then filled it with new topsoil and manure - I don't want to risk eating lettuce grown in diesel-infused soil - and then planted mesclun seeds in the box's soil.

My question is: since it's above the garden's soil level, should I keep it from drying out by covering the box with plastic on sunny days, until the seeds germinate? I already made a chicken-wire cover to keep the cats out. The plastic over the box might help germination by retaining the box's moisture for the needed 10-14 days. Or might it make the box too hot?

I'll also ask this on the vegetables forum.
