Tiny red Insects in my soil | Vegetable gardening | Hydroponics farming in India

Please help me identify the insects in the below video. Also please let me know if they are harmful to the plants and if so how to kill/prevent them organically? i see a lot of these insects in cucumber pots. Theses insects are there in other pots as well.
