Before hydroponics of sweet potatoes, hydroponics containers should be disinfected. After disinfection, an appropriate amount of water can be added to the container. If it is tap water, it needs to be exposed to the sun for 2~3 days. Put healthy sweet potato buds into a glass container, and pay attention to the fact that the buds should contact water. In the process of maintenance, it is necessary to change water and fertilize regularly to promote its germination. In addition, it should be placed in a cool place at first, or in a black plastic bag for more ventilation and sunshine.

If there are sweet potatoes sprouting at home, it is best to put them in water and never throw them away. Trust me, you won't regret it when they grow up for a long time.

Hydroponic sweet potato cultivation method

1, select sweet potato.

Try to choose a bigger sweet potato. Because the nutrients in the early stage are mainly supplied by their own nutrition, the sweet potato is too small and lacks nutrients, and the viewing period is greatly shortened.

Step 2 clean

This step is very important. Sweet potatoes should be washed before hydroponics to prevent rot during hydroponics.

Step 3: containers

Sweet potatoes, like taro and ginger, are afraid of rotting in water. It is best to find small-caliber glass bottles (not too ugly, which will affect the ornamental value).

4. Hydroponics

Add some water and put it in the sweet potato. The water level should not be too high until the sweet potato 1/3. If possible, add some nutrition.

Matters needing attention in maintenance of hydroponic sweet potato

1, water quality

When hydroponics, try to dry it with tap water instead of fresh water. Because the new tap water contains chlorine, it is not conducive to the growth of plants, but the dried tap water can absorb and utilize plants.

Tap water contains a lot of trace elements and is the best hydroponic medium. In the process of growth, there is no need to change water, just add water, and the water level line remains unchanged.

2. Lighting equipment

Hydroponic sweet potato needs a lot of light to meet its requirements, and planting sweet potato needs all-weather light.

3. Temperature

Sweet potato needs a growth temperature of not less than 20℃ to grow normally. When the temperature is lower than 20℃, the growth is very slow and even stops.

Step 4 apply fertilizer

Sweet potato hydroponics does not need too many nutrients, and the nutrients in the water can basically meet its needs. When applying fertilizer, apply fertilizer once a month and drop it into liquid fertilizer water every month. Excessive fertilization will increase its metabolic burden and affect its growth.
