When eating lettuce, cut off the roots of lettuce, and after hydroponics, a plate of vegetables can grow in two weeks at most.

Operation difficulty: ★ ☆ ☆ ☆ ☆.

Operation method: (1) cut off the root of lettuce and leave a few more;

(2) Put the roots in a small container, preferably a small transparent jar, or a cut mineral water bottle, can bottle, honey bottle, bean curd, and Chili sauce bottle ~ If the container is too big or too deep, you can put some small stones for convenient fixation.

(3) The amount of water in the container can ensure that the roots are in the water (let the tap water needed for planting stand for one day in advance). Water is just the root of vegetables, but too much water can easily soak the roots and leaves of vegetables. At the same time, it should be noted that you should be diligent and change the water every two or three days, otherwise the roots will rot ... It is recommended to harvest early and eat quickly, and the roots will rot after soaking for a long time.

2. chives

Hydroponics of shallots are similar to lettuce. The difference is that lettuce is a kind of vegetable that likes shade and avoids cold, and avoids direct sunlight. Onions should be placed in sunny places.

Operation difficulty: ★ ☆ ☆ ☆ ☆.

Operation method: (1) Take onion stems about 6 cm, preferably with some roots on them;

(2) Find a transparent bottle, such as a clean plastic bottle. After washing, cut a knife from the middle with scissors, leaving only half of the bottom. Or cut the mineral water bottle into two pieces, fill the lower part with water, remove the cover from the upper part and buckle the onion upside down, and then put it in the lower part, so that the roots are not easy to rot;

(3) Add some water to the plastic bottle, which is about 3/4 of the bottle, and then put the onion into the plastic bottle. If the onion root is too long, you can also cut it properly. Put it in a sunny place, change the water once a day, and you can see the change in a week.

Celery, onion, etc. Similar to hydroponic lettuce, celery doesn't grow so fast. Onions germinate and take root easily, and onion leaves can be eaten for 2 months.

3. Garlic seedlings

If you find garlic sprouting at home, don't throw it away. Use it to germinate garlic quickly.

Operation difficulty: ★ ☆ ☆ ☆ ☆.

Operation method: Garlic can be cultivated in water after germination, and garlic cloves (preferably peeled) should be placed in a container with little water.

Put it on a plate, in a sunny place, and change the water every day. Generally, it can take root on the same day after hydroponics, and it will be green after 2~4 days. After more than 10 days, you can eat green garlic seedlings and harvest a variety of crops.
