Garlic sprouts are a common vegetable, its leaves are green, delicious, rich in vitamins and trace elements, and have good nutritional and health care effects. Garlic seedlings are usually grown through soil, but in recent years, hydroponic garlic seedlings have also become more and more popular because it does not take up space, does not need to be fertilized, does not need to be weededed, does not have to worry about soil pollution, and can be harvested at any time, which is very convenient. Hydroponic garlic sprouts only need a container, some water, and some garlic to easily grow a pot of garlic sprouts at home that can be enjoyed and eaten.
But do hydroponic garlic sprouts really not need to bask in the sun? This is a question that many people have about hydroponic garlic seedlings. We all know that plants need photosynthesis in order to grow and develop, so how can hydroponic garlic seedlings carry out photosynthesis if they don't bask in the sun? Why are its leaves still so green? Will it taste worse? Let's take a look at these questions.
First of all, we need to understand that the photosynthesis of hydroponic garlic seedlings is there, but it does not need to be directly exposed to the sun's light. The photosynthesis of hydroponic garlic seedlings mainly relies on scattered light, that is, the light entering from windows or lights, although these lights are weak, but for hydroponic garlic seedlings, it is sufficient. Because the photosynthesis of hydroponic garlic seedlings mainly uses the nutrients stored in the garlic to convert them into the energy required for the growth of garlic seedlings, rather than absorbing nutrients from the soil like other plants. Therefore, the photosynthesis of hydroponic garlic seedlings does not need too strong light, as long as there is a little scattered light, it can be carried out.
Secondly, we need to know that the leaf color of hydroponic garlic seedlings is mainly determined by the chlorophyll content. Chlorophyll is a pigment that absorbs light energy, and its color is green, so the leaves of plants are also green. The chlorophyll content is affected by light exposure, and generally speaking, the stronger the light, the higher the chlorophyll content and the greener the color of the leaves. However, this is not absolute, because the chlorophyll content is also affected by other factors, such as temperature, moisture, nitrogen fertilizer, etc. Therefore, the leaf color of hydroponic garlic seedlings does not have to be exposed to the sun to be green, as long as the appropriate temperature, water and nitrogen fertilizer are maintained, the chlorophyll content can be kept at a reasonable level, so that the leaves can maintain the green color.
Finally, we need to understand that the taste of hydroponic garlic seedlings is mainly determined by the content of volatile oil. Volatile oil is a substance that can give off aroma, its composition is sulfur compound, its content, is affected by light, generally speaking, the stronger the light, the higher the content of volatile oil, the stronger the taste. However, this is not absolute, because the content of volatile oil is also affected by other factors, such as variety, growth period, harvest time, etc. Therefore, the taste of hydroponic garlic seedlings does not have to be strong in the sun, as long as you choose the right variety, growth period and harvest time, you can keep the content of volatile oil at a reasonable level, so as to keep the taste delicious.
To sum up, hydroponic garlic seedlings really don't need to bask in the sun, as long as there is a little scattered light, they can photosynthesize and maintain the leaf color and taste. Of course, this does not mean that hydroponic garlic seedlings do not need light at all, if there is no light at all, the photosynthesis of hydroponic garlic seedlings will stop, the leaves will turn yellow, and the taste will become lighter. Therefore, hydroponic garlic seedlings still need a certain amount of light, but they do not need to be exposed to the sun directly, but are placed in a place with sufficient astigmatism, which can not only avoid the drying and damage of the leaves, but also ensure the growth quality of garlic seedlings. Hopefully, this article will help you better understand hydroponic garlic seedlings, so that you can grow a pot of green garlic seedlings at home and enjoy the fun of planting.
