A week ago I planted some black seeded simpson leaf lettuce. As fate
would have it, tonight they issued a frost and freeze warning for my
area with temps. getting down to 29 F. My lettuce is about 1/2" high.
Do you think if I cover it that there may be a chance it will survive?
The next three nights are going to be around 30 F. here.

Temps in the 28-32 degree range will generally not bother lettuce - it's
consider a "half-hardy" crop.
