Lettuce under grow lights

Lettuce under grow lights

After recently being informed that I could grow lettuce under grow lights even in the dead of winter, I'm trying to gather as much information on this process as I can. Are there any special considerations when growing a vegetable entirely indoors? How much sunlight is best for lettuce? Do I need a specific wattage? Will I need to up the fertilizer to compensate for being containerbound? I know lettuce requires constant moisture. Is this going to require one of those moisture regulator devices considering it can't draw water from the surrounding dirt?
