If you read the thread, you'll notice that this is something that is not for everyone. It's posted for you to glean any information from that may be of use in your husbandry. If you find it lacking, then fine.
No one is 'blindly' following John, and I'm sorry if that's what you got from this thread. John has his way of doing things and sharing what works for him.
