A good analogy to that would be deep water culture hydroponics.

Actually, I take that back. Ripariums are deepwater culture hydroponics.

Herbaceous, leafy plants like lettuce usually do well in this type of system whereas tomatoes, squash, etc, will usually rot away, although they may seem to grow well initially. Sometimes "farmers" have been able to overcome this by agressively oxygenating their reservoirs via O2 injection or the addition of H2O2, but may plants just do not enjoy having "wet feet".

I remember seeing a post of yours some time ago where you were growing an African mask plant in riparium. How did that ever turn out? I read up on them and saw several people advising not to over water them.
