two。 Smell with your nose

Smell with the nose is mainly the smell of plant roots and water, if there is some bad smell, it means that the roots have rotted.

The cause of rotten roots

1. The content of dissolved oxygen in nutrient solution is low.

There are many reasons for the rotten roots of hydroponic plants, and the most common reason is the problem of nutrient solution. For example, in the past summer, the content of dissolved oxygen in hot water bottles will become lower, which may cause hypoxia in plant roots.

Solution: put the aquaculture bottle in a ventilated place at home.

two。 The quality of nutrient solution is poor.

If there are substances in the nutrient solution, it may be due to the residual plant debris and residual matrix in the water quality, which will also lead to the deterioration of the nutrient solution.

Solution: change the water every 2 to 3 days and check the quality of the nutrient solution.

3. The nutrient solution flooded the plant roots.

If the nutrient solution submerged all the roots and even the rhizomes of the plant, the roots would also rot.

Solution: expose half of the plant's roots to oxygen and half to the nutrient solution.

4. High temperature of nutrient solution

When the temperature of the nutrient solution is more than 30 degrees, the root system is easy to rot.

Solution: shade the plants properly.

How to deal with rotten roots

1. Cut off the rotten roots in time

After finding rotten roots, take out the plant and rinse the root mucus in clean water. Don't rub it with your hands. Then cut off the rotten roots and leave them in a ventilated place to dry.

Matters needing attention

1. Temperature

The water temperature of hydroponics should be as low as 18 degrees to below 25 degrees. Flower friends should pay attention to putting plants in a cool and ventilated place.

two。 oxygen

There should be enough oxygen in the nutrient solution, and some metronidazole, vitamin B12 and charcoal can be properly put into the water to improve the quality of the nutrient solution.
