Reply #77: Yes, if you like baby lettuces.

I did this last winter, and it worked great (this winter, I accidentally killed the bed. Oops.)

I used a starting flat (it's 20 inches x 30 inches) and put it in my breakfast nook (which faces east and south). I had 2 of them going at the same time, and oversowed as I cropped back a section. I cut baby leaves when they were about 4 inches tall, and put down pearled fertilizer in the soil. I usually had enough greens for 4 salads a week for 2 people. A third flat would have let us have a salad every day. Sometimes I had to let the lettuce recover a bit more than others - weather influenced that a lot.

It's really hard to do organically, though. Indoor beds don't have access to the minerals that outdoor beds do, and the soil depletes pretty quickly when you're doing something as intensive as baby greens. The pearled fertilizer I use is a mixture of fish meal, bone meal, blood meal and potash, so it's not entirely organic, but it's not a petroleum-based fertilizer, either.

I know chard grows nicely as a houseplant. I was thinking of trying a flat of spinach this year, I killed the beds and didn't replant (no time.)
