What type of hydro is this guy using?

Hi, I saw this video on YT and I cant stop wondering what kind of
hydro method it is... I searched on Google about the different hydro methods but I cant seem to find one that fits this guys method. He has blocked commenting so I had to come here and post this question. Thanks for stopping by.


Here is the video.
