Can you still eat onions when they sprout? Hydroponic method!

Onion is a common vegetable in daily life. Although it makes you cry when you cut vegetables, it tastes good, so it is very popular, but it is not durable. It usually sprouts in five or six days. Can you still eat onions when they sprout? How to cultivate in hydroponics?

1. Introduction of onions:

1. Can onions smell bad?

Onions can remove the smell, especially when there is a smell in the bathroom, refrigerator, kitchen and other places, it can be sliced and put inside, and the smell will be absorbed after a while. In addition, it can also be used for deworming, beriberi and so on.

2. Is onion acidic or alkaline food?

Onion is a weakly alkaline food, which is rich in calcium, zinc, selenium and other elements. it produces alkaline substances after digestion, so it is a weakly alkaline food. It usually tastes sweet when fried, but because many people think it doesn't taste good, it is mostly used to make side dishes.

Can you still eat onions when they sprout?

1. Onions can still be eaten after sprouting, except that the nutrients will be reduced, and most of them will be transferred to the germinated part. at the same time, the moisture inside will gradually transfer to the germinating part, so the moisture inside will be reduced and become more spicy. Naturally, it is not as delicious as it was before sprouting, so you can still eat it if you don't mind.

2. Onions can still be eaten when they are germinated but not rotten, and they will not produce toxic substances and will not have much impact on the human body, so you can rest assured to eat them. In addition, the sprouts from onions can be used as onions and taste good. However, I suggest that you should plant a potted plant after sprouting, but like lilies, they will grow green leaves and blossom if they are well raised, so why not do it? Of course, if you don't want it to sprout or plant potted plants, it's best to dry it after harvest and put it in a dry and ventilated place, so it won't sprout.

Third, how to cultivate onions in water?

After onion sprouts, it can be used as a pot plant like daffodils, and it will produce green leaves and white roots, which is very beautiful. The specific methods of hydroponics are as follows:

Step 1, peel off the outer layer of the onion and cut off the root base a little.

Step 2: find a shallow glassware or small glass, add some water to it, then put the onion on it and move it to a cool place. After a few days, the onion will grow leaves and many roots. When adding water, just submerge the root.

When hydroponic onions are cultivated, the key point is to change water. Generally, water should be changed every day within a week after hydroponics. After 10 days, water is changed every three or four days. After 3 weeks, onions grow leaves and roots. At this time, they can be placed in living rooms, bedrooms, kitchens and other places, which can effectively drive cockroaches, help sleep and so on.

Generally speaking, onions can still be eaten after sprouting, but the taste is getting worse, so it is best to put them in a dry and ventilated place so that they will not sprout. Of course, it is all right to sprout, but you can find a transparent bottle and add water to raise it. Green leaves and roots can grow in a few days, which also has high ornamental value.
