An Alternative Way to Set Up a New Planted Tank

While skimming through the threads on Aquaria Central, I came across Tom Barr's alternative method for setting up a new planted tank.  What this method involves is growing in the foreground plants (which are usually the trickiest to grow and plant) in saturated substrate, without filling the tank with water.  In 4-8 weeks, once the smaller plants have had an opportunity to grow in and become more established, the tank is filled and fish can be added. 

The process does look quite easy and if I had a new tank to work with, I'd love to give it a try.
