Matt is just trying to help out all the new people who have not grown outdoors, I guess you think your way is better, but who has the seeds and the knowledge to continue to grow.
He knows what he is doing you just don't like his way, so I think you should do your thing and let people decide who they trust. I am with Matt on this one. But you have a nice day anyway, Don't hate cause he's a great teacher. Peace out.
