Lettuce is a surprisingly easy crop to grow indoors. It has a short-term but plentiful yield and only requires minimal care: standard potting soil, a little water, and a lot of sun is all it really takes.
- Choose a lettuce variety well-suited for container gardening. Loose-leaf varieties are the easiest to grow indoors, especially if the name includes “baby” or “little.”
- Select a medium-sized plastic container. Lettuce does not have a particularly deep root system, so a medium container should offer plenty of room.
- Pour one or two dozen seeds into your non-dominant hand. Pinch each seed in between the index and thumb of your dominant hand, and add a seed to a dibble hole.
- Water your plant every other day to keep the foam moist. Your lettuce may need more or less frequent watering, depending on how warm and sunny your home is.
