Just watched the video and visited the site.

It IS the Kratky method.  He does link to Kratky's research at the bottom of his homepage.

The only thing he talks about that I haven't heard before is using a 3D printer to make the seed net pots from recycled plastic that has been extruded into printer filament.

There is really nothing more than a homepage with a donation site. Absolutely nothing revolutionary. I was at least hoping for he would include his nutrient recipes, I thought maybe they would be revolutionary. He repeats grass roots revolution a lot, but I've seen nothing grass or revolutionary.  He did, however, lift up the lid of his KRATKY container and show lettuce roots.

I went and read the comments and I had this uneasy feeling he's the leader of some kind of a food cult.  People with tears in their eyes over a video that says absolutely nothing? Hmmmm.

FBI turns up heat on Mike Adams as ‘Health Ranger’ fiasco widens, plus Adams’ archive

July 28, 2014 

Last week, Mike Adams, the founder and editor of NaturalNews.com–a favorite site of Dr. Oz and anti-GMO campaigners, from Vandana Shiva to Center for Food Safetey’s Andrew Kimbrell to the Food Babe to Jeffrey Smith, but also dubbed by scientists and journalists as the number one anti-science site in cyberspace–launched an all out offensive against crop biotechnology.

Adams posted a screed on his website (since sanitized by Adams; we’ve included link to the pre-censored version) attacking supporters of genetic engineering as modern day Nazis, suggesting that anti-GMO activists should consider murdering scientists and journalists for their crimes against humanity. Adams then alerted readers to another site, Monsanto Collaborators, which was more or less a handy online list of these so-called ‘Nazi perpetrators”–aka scientists, journalists and news organizations that believe biotechnology can play a constructive role in farming–for crazies who might want to follow Adams’ marching orders and begin assassinations.

So much for love, peace, and food for all humanity....

Yep, he's selling something (big surprise-he's a regular on Dr. Oz, and a favorite of Vandana Shiva and Food Babe)

I wonder if he nailed it about the line of nutrients 

Right on the head.
