Can spinach be grown hydroponically?

Spinach can be grown hydroponically or in soil. Hydroponics has relatively strict requirements on seeds, and it is necessary to select qualified plants suitable for hydroponic cultivation. At the same time, hydroponic spinach requires careful maintenance, and the process is relatively complicated. Compared with soil cultivation, the method is simpler and the cultivation process is easier.

Spinach hydroponic cultivation method

1. Variety selection

   When growing spinach hydroponically, you need to strictly screen the varieties and choose different varieties according to the season. For example, in summer, you must choose heat-resistant varieties, and in winter, choose plants with strong cold resistance. In this way, the plants selected according to the season will grow faster.

2. Germination

   When growing spinach hydroponically, the seeds need to be germinated. In summer and autumn, the seeds need to be soaked about a week before sowing, then refrigerated in the refrigerator, and then germinated at a temperature of about 20 to 25 degrees.

Precautions for growing spinach in water

1. Seedling cultivation

   After the hydroponic spinach is germinated, it needs to be raised as seedlings. It is best to use a sponge with sufficient water and place it in a place without direct sunlight. This can prevent the sponge from being dried out and causing the death of the plant. You can put a layer of moist paper on top to keep it moist.

2. Nutrient solution

   When hydroponically growing spinach, you need to add nutrient solution. The concentration of the nutrient solution should not be too high. In the later stage of the growth of hydroponic spinach, the concentration of the nutrient solution can be increased to avoid lack of nutrition when the spinach is growing vigorously.
