Default Substrate heater installation?

Yes, in fact, it is. It's sort of a law of the universe really. All
members of the biotic community are as they are because they have
adapted, up to this point, to be optimally suited for their environments.

Agricultural crops are NOT grown naturally.

And that's why conventional agrigulture in this country produces not
only terrible food, but severely harms the growers, taints the produce
in clearly demonstrable and harmful ways, destroys the land (that is
_not_ and understatement...US Soil Service estimates at least 70% of US
topsoil has been eroded since white people arrived due to the horrible
cultural practices of the earlier part of the 20th century), and makes
absolutely no room for such grand old ideas as closed-system nutrient
cycling on a farm, revitalizing the soil with carbonaceous matter such
as grain stovers, etc.

A good farm system looks much more like "piece of nature", as far as
doing something "unnatural" like growing human food (as opposed to
gathering and hunting) can look natural. One sees a great variety of
plant types, plants are located such that they are best suited to the
characteristics of that particular ecological niche, heat-loving plants
are growing in the heat of summer, cool-loving plants in spring and fall
(opposite for those in the tropics and subtropics), short-growing plants
are at the south, taller ones at the north (in the northern hemisphere),

Those little eddies are channelized and clog after a while. Unless you
maintain the substrate and replant, uproot etc, substrates will
accumulate too much organic matter after a few months/years.

As I understand it, having read on this and talked to a couple of
commercial aqua plant growers, with regular maintenance of the top of
the substrate, just as with any tank, this is not a problem. If you're
using a UGF, for example, and you never siphon off the mulm from the top
layer of gravel, channeling and dead spots occur.

Further, any tank will have to been torn down and started over from
scratch every so often exactly because it is not a natural environment,
one is only aiming to mimic one, and the tank has no natural means of
completely replenishing and cleansing itself as it would in nature.

I challenge anyone to show any significant improvement in growth using
the cables. I've used them for a decade and never saw any benefit in
some 7 tanks over the years.

It does not make any difference in the ability to make and maintain
and high level of aquascaping in a planted aquaria from anything I've
seen or heard from anyone.

Rarely does a challenge count much in favor of factual argumentation. In
the short paragraph above, you have hardly proved your point. I point
this out because, obviously, this is a subject of great interest to me.
Those who have beautiful planted aquaria are few and far between. Why
would it be that _most_ of those whose published work I've read or whom
I've spoken to advocate the use of substrate heater? I am of course more
than willing to acccept that they might keep to that tenet simply due to
a lack of open mindedness or otherwise, but such has not been shown to
me, certainly not "proved".

Will it hurt your tank? No, but neither will sending me 20$.
You can read George and my discussions on the APD.

Oxfam gets the $20, without question. I will see if I can find your
discussions. Thanks. I've got the substrate heater and am days away from
setting up my 40H tank with it...or without it if someone can prove to
me it will be nothing but a hassle or an eyesore in a couple of years
and will not have been worth whatever benefit new plants might have
received from it before establishment.
