Allan,
	When it's hotter than about 85F I sow lettuce seed in the 
evening, water with cold water, then set ice cubes along the rows, before covering with shade cloth (bits of old tent screen windows actually). Otherwise I do have difficulty getting lettuce germinated in summer.

Sierra is by far our most reliable hot weather germinator. The other 
Batavian types (Nevada, Cardinale, Centennial, Blonde Batavian, 
Kagraner Sommer, and probably the new Magenta) are our best for 
not bolting. De Morges Braun, a beautiful pink and green soft 
leaved lettuce, is pretty reliable, once germinated, and Kalura, a 
big loose green Romaine, did well last year. We're central Virginia, 
then Louisa County Desert, as we call it).

II can't do Black Seeded Simpson here after April 1st, nor Marvel 
after May 15th.
	We do 100 heads a week, transplanted, and I use shade cloth, 47% I think, for two weeks after transplanting. Then I move it on to the new ones. So I need 200 heads-worth of shade cloth to make that work. It's worth the money, and it takes an unnecessary stress off the plants and the grower! 
Once I used old vegatable net bags as shade cloth for about 50 
lettuce, but for 300 - invest!
