Plant cultivation with keyboard

I can harvest anytime when I get hungry, it's exactly two birds with one stone, I do not know how it's like two birds with one stone. This plant is called Cress. You can also say mustard.

All the photos from the beginning of cultivation to the moment of shock growth that has grown completely are placed on the following page.
Can you grow cress in a keyboard ??

First remove the cover of the desktop keyboard and expose the key, spread soft cotton there. I only plant seeds and grow them. It will be a hard thing to do when colleagues grow cultivating while going on a long business trip and get back.
