Emotional Lettuce

So, in the last post I mentioned that I re-potted the lettuce plants because they didn't need as much sun as the rest of the plants AND I also mentioned the weather was supposed to be pretty hot this week. So, I moved the newly potted plants to the corner of the driveway where it gets the shade from our tree and a little bit of sun in the afternoon.

Well, yesterday when Max came home he told me that my lettuce plants were all wilted. The leaves were laying flat on the soil. I took them inside to the air conditioning and gave them some cold water. After about an hour or so, they were mostly perked up. I kept them inside overnight and today I put them in the window sill.

I have no idea how much sun they should get or what temperature they grow best at. I didn't have high hopes for them in the beginning when I threw a couple little seeds in the ground but now that they are 4 inches tall, I kinda want to save them.

Any advice would be helpful!
