How to avoid overgrowth of indoor seedlings?

Some people like to grow some small vegetables at home, such as bok choy and cabbage, so they buy some seedlings, but after sowing, they find that the vegetable seedlings grow out to be long and slender, not strong and easy to break, which is what we call the problem of seedling growth. In the process of seedling planting, how can we avoid the growth of vegetable seedlings and how to remedy the problem after the growth, we will look at the following.

Firstly, we need to understand the causes of seedling growth. There are four general reasons for the growth of indoor vegetable seedlings.

The first is a lack of light. Plants are all phototropic, so we can use light from LED plant lights to guide growth. Because seedlings need supplemental light sufficient lighting to promote internal photosynthesis during germination and growth, it is generally difficult to ensure sufficient light indoors, therefore, the use of LED plant supplemental lights can ensure that there is sufficient light to promote the growth of seedlings.

The second is that sowing too densely causes the vegetable seedlings to block each other’s light and compete for moisture. At the time of sowing, the seedlings do not absorb enough nutrients during growth due to the dense spacing of the seedlings and have less light in the soil, resulting in uneven growth. Therefore, attention should be paid to the spacing of the play, and for seedlings that have grown densely you can appropriately pull out the denser seedlings and use the method of interplanting to increase the distance and ventilation between seedlings to ensure that there is sufficient space for growth.

Thirdly, the temperature is too high. Indoor seedlings are usually kept at around 20 degrees. If the temperature is too high you can add some wind sources, such as small fans, to promote the flow of air between them and ventilation.

The fourth is too much water. The growth of vegetable seedlings is also closely related to watering. Because evaporation is very low in pots or seedlings kept indoors, and watering is too much, seedlings can easily grow, so it is important to water thoroughly at once and then wait for the soil to dry out before watering. This ensures that the seedlings have the right amount of water without causing any growth.

On the one hand, you can increase the light, water less and increase the ventilation. Another way is to rip out some of the weaker seedlings that have grown badly. If the growth is too great, you can also choose to reseed the seeds.
