I tried germinating lettuce outdoors and had a poor germination rate. Then I read somewhere that they may need light to germinate (I had buried them).
I grabbed a container with sifted compost I had lying around, watered it and threw some seed without covering them. I left it under the shade of a tree, with some sunlight but not direct.
Now, 3 or 4 days later, a few already have cotyledons so I need to expose them to more light so they wont get leggy. But the rest all have a radicle showing, and I am worried that more light may damage them.
Since most already germinated and have a radicle out, can I cover them with more soil? or more light wont damage them?
