"Hyperventilating"

[Casemon]

Hi everyone, new to the site; looks very useful!

Question about something I read on the FAQ. Specifically, does anyone have any more information on the "hyper ventilating" growth process?

Supposedly involves sealing the plants and alternating between pure C02 & Oxygen environments to result in drastically shorter growth times.

I would like to learn more and the FAQ is the only page that google finds on this process:
How long does it take to grow a hydroponic plant? - Hydroponics Online

Is this a reality or just fantasy? Anyone have more info?
