Can You Grow Lettuce Indoors by a Sunny Window?

It's possible to grow lettuce indoors by a sunny window, but you may garner better results with some artificial light. Give it a go by choosing a sunny spot and understand that your plants might turn out leggier than when grown with artificial light. Loose leaf lettuce varieties that are recommended for indoor growing, because they are ready to harvest sooner and take less space to grow. The "Old Farmer's Almanac" recommends leaf lettuce varieties such as merlot, dalad bowl and lollo rosa.

Knife
Lidded plastic container
Potting soil
Loose leaf lettuce seeds
Spray bottle or kitchen sprayer

Instructions

- 1
  Poke the tip of a knife through the bottom of the plastic container in about eight spots to make holes.
- 2
  Place a bag of potting soil in a sink and fill it with water until the water starts to seep out of the bottom.
- 3
  Scoop the potting soil into the plastic container and fill it about 3/4 full.
- 4
  Spread a pinch of lettuce seeds evenly across the soil in the container and lightly cover them with soil.
- 5
  Spray a light mist of water over the top of the soil. Use a spray bottle or the kitchen sprayer turned on low.
- 6
  Place the top on the container and put it in a sunny, south-facing window. Do not remove the lid during the germination period. The lid should seal in enough moisture that it's unnecessary to water the seeds.
- 7
  Remove the lid when the seeds start to germinate, about five days later, and place the lid underneath the container so it catches any excess water.
- 8
  Water the plants every day, after germination, to keep the soil moist.
