How to prepare and use nutrient solution for hydroponic plants? Detailed method

First, let's look at the advantages of growing hydroponic plants compared with soil-grown plants.

1. The nutrient solution for hydroponic plants is prepared according to the growth needs of the plants, so the flowers produced are large and abundant, with a strong fragrance, vivid colors and a long flowering period.

2. Hydroponic plants only need to be given a nutrient solution supplement regularly, which is simple to do and saves labor and time.

3. Clean, free of weeds, and with few pests and diseases.

The nutrient solutions for hydroponic plants sold on the market today come in a confusing variety, and for beginners with hydroponic plants, it is easy to accidentally buy inferior products. Preparing the nutrient solution at home, however, can both guarantee quality and save money, and you can also enjoy the fun of DIY.

Before learning how to make nutrient solution for hydroponic plants, let's understand how the nutrient solution should be used.

1. Shake to increase oxygen. Fix the flower plant with one hand, and with the other hand hold the container and gently shake it more than 10 times. After shaking, the dissolved oxygen content of the nutrient solution can increase by about 30%.

2. Increase the frequency of water changes. Changing the water means replacing the water in the bottle that has nutrient solution added. Generally, in spring and autumn, change the water once every 5 to 10 days; in summer, change the water once about every 5 days; in winter, change the water once every 10 to 15 days. Home-grown hydroponic flowers should use soft water as the water source, and generally tap water that meets national standards can be used. After letting the tap water sit for two hours to half a day, wait until its temperature is close to room temperature and the chlorine in the water has volatilized completely, then add the purchased nutrient solution in proportion, and it becomes a nutrient solution that can be used to grow hydroponic plants.

3. Add an appropriate amount of "solid oxygen" to the nutrient solution or add 1% hydrogen peroxide (3% hydrogen peroxide solution).

4. Use a miniature submersible pump or an oxygen pump (both are standard aquarium products) to aerate the nutrient solution. In such an environment, plant roots can obtain sufficient oxygen, promoting robust growth of the flowers.

Now that you know how to use nutrient solution for hydroponic plants, let's learn how to prepare the nutrient solution.

1. The various elements used when preparing nutrient solution for hydroponic plants and their amounts need to be determined according to the variety of plant being grown, its growth and development stage, its flowering time and the final growing region. When preparing it, let the tap water sit for two hours to half a day, wait until its temperature is close to room temperature and the chlorine in the water has volatilized completely, then add the concentrated nutrient solution in proportion, and it becomes a nutrient solution that can be used to grow hydroponic plants.

2. There is also another point: bicarbonate can also hinder the roots' absorption of iron. Therefore, when using tap water to prepare nutrient solution, a small amount of sodium edetate or humate compounds should be added to treat the chlorides and sulfides in the water.

Commonly used nutrient solution preparation amount: add 0.22 g of ammonium phosphate, 1.05 g of potassium nitrate, 0.16 g each of ammonium sulfate and ammonium nitrate, and 0.01 g of ferrous sulfate to 1 liter of water, and mix evenly to make the nutrient solution. Metal containers must not be used for preparing and storing nutrient solution; it is best to use ceramic, plastic, glass or ceramic containers.

The most important care for hydroponic plants is changing their water, and when changing the water, attention should also be paid to adding the nutrient solution.

1. Tap water can be used for changing the water, but it is best to let it sit for one to two days. Directly using mineral water or purified water is also fine. The temperature difference between the original water and the new water should not be too large. After adding a 6ML packet of nutrient solution to clear water in a 2.25L large cola bottle, use it. For a 300ML bottle of nutrient solution, add one bottle cap of the original liquid to clear water in a 2.25L large cola bottle, then use it. The diluted nutrient water has a shelf life of 6 months; keep it away from sunlight during normal storage.

2. In winter when the temperature is below 10 degrees and in midsummer when it is above 35 degrees, the concentration of the nutrient solution used should be reduced (generally to 1/3-1/2 of normal) or only clear water should be used for growing.

The above is some small knowledge about nutrient solution for hydroponic plants. I hope it can help you in the process of growing hydroponic plants.
