Head lettuce germination

mlarsen_growerJune 28, 2008

I have been growing head lettuce and baby leaf lettuce for about a year. All of a sudden I can't get my had lettuce to germinate. I sow in a light potting mix in 72 cell. The soil is nice and moist, but not wet. I either sow directly on the soil surface or sew and then cover with a light layer of vermiculite. I then cover the container with plastic wrap to contain the moisture, place on a grow table under light and ... nothing happens. My seed is good because I have sown it directly in the grown for baby lettuce and had no trouble with germination. I have also successfully germinated these varieties previously. Any suggestions would be appreciated.

Lettuce needs cool soil and the seeds do not like to be covered so skip the vermiculite covering.

What I do is sow seed directly onto soil blocks, water and cover with a piece of plastic just to keep moisture in the dirt. I do not put them under lights until they germinate.

I know some people put the flats in refrigeration in the summer to get the lettuce to germinate
