Call for Spanish speakers

A few days ago I engaged on a journey to soak my way to victory. First on the list, the Sapphire Tower seeds. It is crazy difficult for me to find anything about germinating these guys, but I found what I think is a Spanish how-to guide. I only have intermediate Japanese, which doesn't help me here, but I thiiiiink he is saying he lets it soak for a few days. At the very least I was able to follow some of the imagery he displayed, soaking and then planting in a covered soil cup.

Here is the link in case anyone fluent can help me out:
