Counterfact: Maybe the radiation from the hot Florida sun beating down on the 
plant ponds warms the dark mud substrate and has the same effect as heating 

Counterfact: Ummm, Tropica grows most of their plants emersed and we don't. Thus 
the plants hae never been in water, either. 

> FACT:  Plants raised in Florida have never had "laterite".

Counterfact: Plants growing naturally in SE Asia have had a lot of laterite. 

> FACT:  The largest variety of aquatic plants are raised in Florida.

See Counterfact 1.

I've never seen the mud base in the Everglades but I don't think I would want it 
in my living room, what with the poor aesthetics and rich bug life.

Counterfact: Even more tomatoes are raised without the presence of fish.

Counterfact: Under-fertilization brings on algae.

Gee, Pushak was right!

What's the official smiley variant for "Well, Duh!".  Sorry, too crusty.

I was probably not much help here but I feel better now. Thanks for putting up 
with me.

I think Amano also does this but on a larger scale.
