Looking at the posts in Walstad's section over at the AB forums, I see a lot of people there having long term problems with her method. It appears to me that those problems stem from the definition of 'dirt' and all the results from variations of its composition. I see Tom Barr's approach as being more reliable and simple because the variables can be identified, quantified and controlled. To me, growing plants underwater seems to be more closely related to hydroponics than houseplants. The professional hydroponics folks remove the 'dirt' variable as well.

Hydroponics is a good analogy. How many people do you know doing hydroponics for the fun of it??

I've thought of doing it for quite some time, but I'd have trouble explaining it to the people around me, mainly my wife. She's already got a dubious view of the aquarium.
