There are many roots in hydroponic spring rain, so there is no need to change bottles.
If there are too many roots in hydroponic spring rain, you don't need to change bottles, just change the water frequently and keep enough oxygen in the water. With more roots, more organic matter, wastes and toxins will be discharged into the water, which will be deposited in the water after a long time. Therefore, water should be changed frequently at ordinary times, so as to keep plants healthy and not absorb harmful substances.
There are many roots, so don't build them. The complete root system can resist the infection of germs and will not rot. If some roots are cut off, many wounds will be formed, which will easily lead to root rot. If the water is not changed in time, it is easy to cause the death of plants. We must pay attention to this.
