I have tried once to use some water gel beads in one of my really short plumies, it revived the cutting, but I think my timing was off, it was heading into late Fall, I should have pulled it out and stuck it in dry media as soon as it plumped up. I ended up losing that cutting.
I would heed Hetty's advice. And it is still relatively cool right now in our areas, it maybe more injury to do the water soaking method. Maybe if it were summer already. But not this winter time.
I watched the video link you provided Lucky, and looking at the video, I have seen his videos too, and he is a SoCal grower, so his ambient temperatures are warmer and he posted the video in August, the height of summer. So got to consider too the seasons we are in.
