How to Change the Water for Hydroponic Flowers? A Detailed Guide to Daily Care Methods

1. Change the water regularly, following the principle of changing the water when it becomes slightly cloudy in the hydroponic container. Generally, in spring and autumn, change the water every 10-15 days; in summer, the replacement cycle is about 5 days; in winter, change it once every 30 days.

2. Each time you change the water, first rinse the roots of the hydroponic flowers and the hydroponic container with clean water, and wipe the dust off the leaves with a damp cloth to keep the leaves clean, and prune dead branches, withered leaves and rotten roots.

3. When changing the water, add 4 bottle caps of hydroponic nutrient solution per liter of clean water (cooled boiled water, mountain spring water, magnetized water and other water sources are preferred; if tap water is used, it needs to be left to settle for more than 6 hours), and shake well before use for hydroponic flowers.

4. When adding water, the number of flower roots immersed in the water should not exceed 1/2, with the remaining roots left in the air inside the hydroponic container, and keep the roots drooping naturally as much as possible; afterward, you can occasionally shake the water in the hydroponic container.

5. Pay attention to maintaining ventilation, and the placement location should have a certain level of air humidity. If the air humidity is insufficient, spray mist-like clean water into the air to increase air humidity. Usually, you can spray a small amount of mist-like clean water onto the leaves, or wipe the flower leaves with a damp cloth to keep them clean and dust-free.

6. Hydroponic flowers can generally be placed in indoor environments such as offices, meeting rooms, lobbies, coffee tables, next to computers, kitchens, bedrooms, living rooms, and bathrooms. When placing them, put them in a spot indoors with relatively sufficient sunlight (that is, a sunny spot with more scattered light), but avoid direct sunlight and cold wind.

7. Indoor temperature should preferably be controlled between 8°C and 30°C. If the temperature is too high, you can use air conditioning, spraying water, water curtain cooling and other means to lower it appropriately, and at the same time be sure to strengthen ventilation; in winter, pay attention to keeping warm for overwintering, and often let them receive scattered light or direct sunlight. If extreme low temperatures occur, you can use a heater to increase the ambient temperature, or cover the hydroponic flowers from top to bottom with a thicker transparent plastic bag, and make 3-4 holes in the plastic bag for ventilation, and prevent cold wind from blowing on them.

8. If rotten roots are found on hydroponic flowers, remove them thoroughly in time. First, use clean pruning shears to cut off the rotten roots from the base in one go; then disinfect the roots with 0.5% potassium permanganate for 10 minutes, and rinse them clean with clean water. After that, use clean water (or magnetized water) and fix them with a planting basket for suspended water culture for 7-15 days, changing the water once every two days. After new water roots grow, you can add an appropriate amount of nutrient solution for normal hydroponic culture.

9. If conditions permit, you can also add 1% hydrogen peroxide (that is, 3% hydrogen peroxide solution) or 0.1% potassium permanganate to the hydroponic nutrient solution to help release oxygen or inhibit the growth of harmful bacteria and algae in the water; of course, you can also add a small amount of microbial fertilizer or activated carbon to the hydroponic nutrient solution to improve water quality and make it more conducive to absorption by plant roots.
