1、 Rice washing water

When washing rice, collect the water that has washed rice for the first time and put it into a bottle. Then move it to a place that can be directly illuminated by the sun and put it for about 20 days. Then pour it into a large bucket, and then add 50 times the volume of clean water to the bucket for dilution. Finally, put them into a bottle and add a few drops to the container of hydroponic asparagus every week

2、 Compound fertilizer

The dissolved and diluted compound fertilizer can also be used as its nutrient solution. The specific configuration method is to take several grains of compound fertilizer and put them into a basin, and then add some clean water to the basin. When the flower fertilizer is completely dissolved, mix the water well, and then put it into a bottle, which can be used as its nutrient solution

3、 Precautions

For hydroponic plants, nutrient solution needs to be added, but not too much. Because the nutrients in the water are not enough to meet its growth needs, it should be provided with some nutrient solution to help it grow. However, it is not allowed to add too much or apply too thick nutrient solution, because it is easy to damage the root system of the plant, resulting in its inability to absorb nutrients, resulting in poor growth
