1、 How much water

The water level should also be appropriate when raising green pineapple in water. Generally, for plants, it should not exceed most of the roots, and at least 85% of the roots should be in the water, so as to ensure that it can absorb water normally and will not hinder future growth. If you haven't grown roots yet, you need to keep the water below one or two stems, which can promote it to grow roots. The height of the water level is very important. If the water level is low, it is difficult for the roots to absorb water, and the growth will be limited and difficult to supply to the later growth, which may lead to the decline of growth due to water shortage. If the water level is too high, it is difficult for the roots to breathe normally, which may lead to root rot and affect the whole growth

2、 Other precautions

1. Water change: in addition to ensuring the water level, pay attention to the water quality. Generally, the water is changed every 4-5 days during the growth period. The temperature in summer is on the high side. Change the water for about three days, so the water quality cannot be turbid. It's cold in winter. You can change the water once in 5-7 days. At this time, you don't have to change it too often

2. Nutrition: in addition to daily water change to provide new nutrients, it is also necessary to add an appropriate amount of nutrient solution during water change, which can promote growth
