Haven't seen it, but here's an excerpt from Apollo Aquariums in
Singapore: (http://www.netv.com.sg/apollo)
"Let's look at the Amazon swords. They are initially grown
with the leaves above the water level in aquatic planter
boxes. When the Amazon swords reach a certain size, we
pump more water into the boxes until the plants are totally
submerged."
It makes sense, because if you have a large planter box filled
with swords, you are definitely going to run up against the CO2
diffusion rate into the water. Growing them emersed will give
you much faster growth in this case.
