What's wrong with just a sheet of plastic to stop the soil drying out ?

Plastic stops the soil "breathing"

Plastic is also the material you use to solarise your soil. By that I meant hat you use the plastic to heat up the
ground to kill weeds. It would do the same to lettuce.

Not if you cover it with something like straw, masonite etc.
