Odd Question.

[CBBP]

This is more about terrestrial plants but...

Are their any plants that like to have their roots completely covered in hard basic nitrate saturated water? The grow fast and in air?

Not sure if this is the answer you are looking for but there are lots of plants that would be considered marginal plants, these plants will grow in and out of water, imagine a rivers edge where the water level will not remain the same due to floods rain etc, this is where you would find marginal plants in nature.

Not sure if thats what you mean though.

Java fern grown emergent and 'lucky bamboo' (Dracaena sanderiana) work. I had lucky bamboo in a tank with coral sand and a pH of 8 .

Pothos cuttings will grow in water alone. Roots and stems submerged, leaves in the air. If this is what you mean? I do this all the time at home. We have a pothos plant in a crystal bowl filled with water. The leaves are in the air, but the stems and roots are submerged. It is doing well and has been in this growing state for nearly a year. Unfortunately, the cat likes to drink from that particular bowl, so only natural fertilisers are used (a little tank water). Pothos also does well in normal room light, which is also pretty cool. A pretty much indestructable plant.
