Hello, dear friends, welcome to visit Dr. Yang’s life tips channel. I’m Dr. Yang.
Today, I would like to share with you a hydroponic vegetable that can be grown without seeds and using the leftovers in the kitchen.
These are two cabbages that I have contained in the water at home. On the right is "Sweetheart" cabbage, and on the left is ordinary cabbage.
There are mainly two kinds of cabbage to share with you today. One is cabbage, which is also called leafy cabbage in Hong Kong.
Taiwan is called cabbage. It is a variety of cabbage. The common name is also called cabbage and kohlrabi.
The cabbage heart is planted directly, or hydroponic for a week, and then planted in the vegetable field outside.
The second kind is the pointed cabbage, also known as the sweet cabbage. There are green leaves and very pointed heads.
Its leaves are more open than cabbage, soft in texture and sweeter in taste.
Similarly, we can plant the cabbage directly, or plant it after hydroponics.
This is a week after hydroponics. Generally, the water is changed every 1 to 2 days.
A week later, it can be seen that a lot of small cabbages (small buds) are coming out from here.
Then, these buds will grow up day by day. In fact, after a week, this kind of roots often begin to grow underneath.
Because this kind of roots is very important to provide nutrition.
After 2 weeks of hydroponics, you can see that this small cabbage is gradually getting bigger. The leaves of cabbage are wider.
Two weeks later, the root system underneath developed more vigorously.
After this, these roots will provide nutrients to the new cabbage sprouts.
These sprouts should be placed close to the light. It requires photosynthesis.
Change the water every day. In this way, pollution is less likely to occur.
This is hydroponic 3 weeks later. You can see it at home, the cabbage on this top is stronger, and the leaves of the cabbage have become thicker.
This is 5 weeks after hydroponics. Everyone can see this obvious change.
This kind of hydroponics is very successful. You can see it from above, there is vegetable moss growing on it.
Today, we are here, picking the leaves, making soup, stir-fry and eating them.
Just change the water every day, and then it will grow so well.
Now, this is the second harvest. So, there is no fertilizer, why can it grow so well?
Are there so many nutrients in the water?
You can look at the vegetable moss that grows on it.
This vegetable moss and cauliflower are very beautiful.
Here, look at a cauliflower here. There is also a vegetable moss in this place.
This vegetable moss is a bit tall. I picked it off and ate it. Otherwise, they are elder.
This one is also picked. It's still tender now.
Next, let me show you how to accompany this kind of pointed or sweet cabbage with water.
The method is the same. After a week of hydroponics, you can see that small cabbages are coming out from this side.
Then, in a week or so, it gradually grows.
After 2 weeks of hydroponics, the leaves on the top gradually enlarged. At the same time, below, you can see the growth of this kind of roots.
Like the dragon's whiskers, it is also very beautiful.
Then, these roots provide more nutrients and help the growth of cabbage.
This is hydroponic 4 weeks later. As you can see, the top leaf has grown very strong.
The leaf on the side also grows very big.
The water is still changed every day, sometimes even 2 days.
This is 5 weeks after hydroponics. The cabbage grown has reached a certain size.
As you can see, the leaves of cabbage have also become thick. The color also deepens.
In fact, when the color is darker, it will have more nutrients and more chlorophyll.
So, I put it on the window sill against the sun. In this way, it will get more sunlight during the day and help photosynthesis.
At the same time, after 5 weeks, you can see that the roots below are also stronger.
The small cabbage grows up day by day. As you can see, 3 leaves have grown out today.
The fourth leaf also grew.
Therefore, as long as there is water, it can grow tender green cabbage leaves. Great!
I now pluck the leaves of cabbage for cooking.
Its leaves are still tender. However, I find it very strange!
This dish, I water it every day, without adding any nutrients, it can still grow so well.
So, the biological world is very, very interesting.
Next, I will introduce to you the method of hydroponic cultivation indoors, and then planting outdoors.
Let the cabbage grow to a certain extent indoors using hydroponics.
Above, everyone can see that some vegetable moss has appeared. Later, it can also bloom this kind of cauliflower.
When the leaves of this indoor hydroponic vegetable grow to a certain extent, the root system underneath will develop better.
You can see the root system below. Very, very healthy root system. no pollution.
At this time, you can transplant it in a flower pot, or transplant it to an outside vegetable field.
Because it already has a root system, it is easy to survive.
In addition, in this soil, after transplanting it into a flower pot, I planted it in the garden.
Photosynthesis is better, and the nutrients in the soil are also richer.
As you can see, the leaves of this cabbage are healthier and the color is deeper.
Well, today I will give you a brief introduction here.
