That's taken from the
Mandala Seeds website, which should be mentioned, and who's method I tried with one of their Kalichakra seeds a month ago. I'm still waiting for it to sprout. Also tried one God Bud seed, one Santa. I'm still waiting on these, as well. In the meantime, I used the warned against method to germ a Fast Bud, which is about to flower, and a Blue Widow.
So, I consider their advice to be sincere, and it's well-taken by me, but in the colder months I'm going to make sure my seeds crack. I'll risk the hazards they warn about.
To be clear, I'm a fan of Mandala Seeds, but taking their advice set me back.
