Your surroundings also greatly affect the quality of your hydroponic vegetable garden. If you have a spacious yard but around a lot of smog, pollution or many tall buildings block sunlight, it is not good for trees. 

The areas around the planting site that you need to pay attention to include: the left, right and front sides of the yard. 

If your terrace is lower than other houses, around 3 sides are covered by high-rise buildings, even if the yard faces the direction of the sunrise, the plantability is also very low. 

One way to help you solve this problem is to change the corrugated blood on the roof of the terrace into clear plastic sheets that will help improve the lighting condition of your hydroponic vegetable garden. 

In summary, the requirements for hydroponic vegetable planting include: The minimum light per day is 6-10 hours, the surroundings are well ventilated and limited to being shielded. 

Depending on the terrain conditions of your family, you proactively take appropriate response measures to ensure the best environment for vegetable plants to grow.
