  1. First, you need to buy a ripe lettuce fruit at the store and eat it. Only it is important not to damage the core. When the lettuce is eaten, cut the leaves 2.5 cm from the bottom. This piece will become the future salad.
  2. Pick any shallow dish, pour water into it about halfway and put the core into it. Put the container on a window sill, and then change the water every two days.
  3. After 10-12 days, the lettuce will be big enough to be cut and eaten. But do not grow lettuce beyond this number, as it will be bitter and unpalatable.

You will need a glass jar with a wide neck. You can put some clear pebbles in it beforehand to stabilize the core. In addition to stones, you can also use wooden skewers that are poked into the base of the core. Such sticks can be inserted in the core of up to three pieces to make it more stable. In addition to wooden skewers, you can use ordinary toothpicks.

  1. When the core is in the jar, pour water to cover the core up to the middle.
  2. Next, it is better to provide the plant with artificial light, which will help grow lettuce more quickly. If this is not possible, place the jar on a windowsill closer to a source of sunlight. But it is important to avoid direct sunlight.
  3. The jar should be changed every other day, where you can pick up water with starchy waste. For example, you cooked pasta, or peas. This water would be good for a salad.

Hydroponic fertilizers will help accelerate the growth of lettuce. After 12 days, the lettuce can be cut and eaten.

The process of growing romaine lettuce in water is very simple and can be done with a few items you may have at home. All you need is:

  • A container or pot of soil;
  • Romaine lettuce seeds;
  • A small dish or cup in which to place the seeds;
  • Warm water for watering.

First, you need to choose the right soil to grow in. You can take regular vegetable garden soil, or you can buy a special kind at a gardening store. First, the soil should be well calcined, in the oven at 180 degrees for 1 hour. Then let the earth cool down

Before sowing the seeds, they should be soaked in a solution of water and salt, where the dosage is 30 grams of salt per 1 liter of water. All the seeds that will float within 5 minutes, throw away, and the rest will be suitable for growing lettuce. They should lie in the solution for 6 to 24 hours.

Plant the seeds in a container with soil measuring 60*60 cm. Planting goes to a depth of 5-7 mm. Then water it, cover it with foil and put it in a cool and shady place. When the first sprouts appear, then immediately move the lettuce to the light. Avoid direct sunlight.

Romaine lettuce is one of those varieties that can be grown in a variety of conditions. You can grow it from seed or from the core, and you can do it both indoors and outdoors. Features of growing romaine lettuce:

  • Romaine lettuce likes clear water, but it also likes starch-rich water. If you’re worried that you won’t be able to provide plenty of nutrients to the water, it’s better to buy special hydroponic fertilizers;
  • Lettuce needs a lot of sun, or else it will be bitter and unpalatable. It is very important not to put the lettuce in direct sunlight, or else it will get a burn;
  • Do not let lettuce grow longer than 12 days, because it will start to seed and will taste bitter;
  • If you see that the leaves are starting to turn blue, the lettuce is already forming seeds, and it might taste bitter;
  • If there is mold on the core, you need to throw it away and start over;
  • If the core does not sprout after a week, you should throw it away and start over.
