I do no have hydroponics system but something happened like hydroponics. I would like to explain with this picture:

{{gwi:1009122}}

The container is not self-watering system just I use the plastic bowel to avoid excess water drain on the floor. The container bottom is not touch the bottom of the bowel it has space. Today I cleaned the containers and found that the roots come out from the drainage holes touch the excess water in the bowel and there is no root damage they are white and fresh. Same thing happened to my tomato plant too.

So should I trim the roots or should I added some fertilizer to the excess drainage water in the bowel? Is there any negative consequences if the roots touched the water like this way? In case of container plant, flooded root is caused to death of the plant.

In this situation I firmly believe that add some liquid fertilizer to the water in the bowel would be very beneficial for the plant. However I am not an expert so, please give me some tips to use this experience useful.

Thanks in advance.
