Key points for the maintenance of hydroponic flowers

Whether hydroponic flowers should be changed regularly

The hydroponic flower root system is soaked in the nutrient solution, and the buffer capacity of the nutrient solution is worse than that of the substrate. Due to the metabolism of plants, new roots continue to grow, and the roots may also secrete some toxic substances, which have adverse effects on root growth and development.

In addition, because different flowers have different absorption of nutrients, it is selective, so it often causes nutrient imbalance in the nutrient solution. Sometimes it will cause physiological diseases caused by element deficiency, and it will also cause imbalance due to the effect of temperature on PH, especially in hydroponic culture.

Therefore, hydroponics should be changed regularly. The liquid was changed once a month in winter, spring, autumn and each season, and once every 25 days in summer. Therefore, a good nutrient solution must have a strong buffer capacity, which can stabilize the plant growth environment and ensure the balance of nutrients.

Management of ◆ water

In general, the cultivation water in the basin should be changed once a month or two, and the tap water in daily life can be used, but note that when the water temperature is lower than the indoor temperature, the tap water should be placed for a period of time to keep the root temperature stable.

Hydroponic flowers are mostly negative and neutral flowers suitable for indoor cultivation, and flowers have their own requirements for light. Negative flowers such as ferns, orchids, Araceae, should be moderately shaded; neutral flowers, such as turtle back bamboo, goose palm wood, poinsettia, etc., do not have strict requirements for light intensity, generally like plenty of sunshine, can also grow normally in shade.

It is important to ensure the temperature at which flowers grow normally. The root system of flowers grows well in the range of 15 ℃ ~ 30 ℃, and most flowers will not die above 5 ℃, that is to say, it is necessary to keep the temperature above 5 ℃ in winter to ensure that most flowers can survive the winter safely, and a few flowers can survive the winter at 0 ℃ according to the characteristics of the varieties.

Attention should be paid to identifying the root color of flowers to determine whether they are growing well. The whole root or root system with appropriate light, temperature and nutrient solution concentration is white, and some plant roots show other night colors. Please pay attention to forbid excessive nutrient solution and shorten the time interval of adding nutrient solution.
