from my own
experience, I have not been successful trying to grow lettuce shoots or plants indoors as it take too long to sprout & grow and the stems are week.
My best success is radish shoots & Buckwheat shoots for winter salad. Sunflower shoots are great but annoying to pick off all the shells as they do not all fall off on their own.
So this winter, I am focusing on radish & buckwheat shoots and a bit of sunflower shoots. I have read Peter Burke's book and have adapted it to growing in larger 10'' pots in an outbuilding that is already heated. Also, to keep seed costs down, I buy them in 5lb bags, so that is why I limit the variety.
Not only do I use the shoots in salads, I use them like cooked spinach by adding them to soups, stews, gravies, stirfries etc...
