Re: Open discussion
Please bear in mind that most of my answers are hearsay.

Florida Aquatic Nursery is the largest.

IMHO, undergravel heating is overrated in Tropical locations. I don't
know of anyone who has undergravel heating in their ponds. FLorida has
a great number of ponds because of its climate. Tropica has a
temperature controlled facility. Since the plants in Tropica are
floating on a river of liquid, there is no undergravel heating. Heating
the water is sufficient.
> FACT: Plants raised in Florida have never had "laterite".
As far as I know, the Florida growers use soil to grow their plants in
outdoor pools. Laterite is not used. However, bear in mind that most
growers use open systems that maintain low nutrient levels.
> FACT: The largest variety of aquatic plants are raised in Florida.
I don't know about this. Tropica has a very large selection.

The Everglades has very few plants that we can use in our aquariums.
There are some cyrptocorynes near lake Okeechobee.

I would tend to agree.

Well, maybe. As long as you use an inert sand, does it matter?

If a deficiency occurs, I think even a beginner better fertilize or lose
the plant. I agree with your second statement.

Again, IMHO, some people rely too much on fertilization by fish poop and
fish food. I don't know about anyone else, but my experience is that my
fish don't provide the all the trace elements needed by plants. In
really, I see much nore NO3 and PO4 being provided by fish.
However, I do believe that one aquarium will always be different from
another, even if you have the same plants and fish.

ADA has an army of people working on their aquariums every morning.
Trimming and water changes is what they do most.

There was an interesting thread in FISHNET titled "Are we Artists or are
we Scientists?". I believe TAG may someday carry it. It was a very
interesting discussion. In the end, I hope to be both.
