If you can’t find the seed mix in the first place, you can also make an equal amount of peat moss or coconut, vermiculite, and sand to make the soil.

Each lettuce plant requires a space of 10-15 cm and a depth of about 20 cm. choose a pot that can accommodate these dimensions.

  • Pot with a drain hole on the bottom. Place the saucer under the pot to catch the drainage.

Caring for Indoor Lettuce Plants

  1. Spray the seeds daily until the seedlings sprout. Give your lettuce at least an inch of water a week when they sprout. Stick your finger into the soil once or twice a day, and when the soil dries, water the lettuce.
  • The soil should be moist, but not soaked.
  • Another way to test the moisture content of the soil is to raise the pot. If it feels heavy, the soil is saturated with water.

  • When the outside weather is warm enough or cool enough, you can take your plants out regularly for fresh air.

  • Use liquid fertilizer. Granular fertilizers need to be mixed with the soil.
  • Both organic alfalfa and nitrogen-rich sustained release fertilizers work well with lettuce.
  • Emulsified fertilizers of fish and algae can also be used, but they can give off a strong odour and are not recommended for indoor lettuce plants.
