It sounds like they shunt all the gray water to one line that
can be switched to the garden, or the sewer.

Was that the question?

yes, water being scarce out there i can't
imagine it being feasible to keep a large
rooftop garden off the regular water supply.

I would say try hydroponics but it was invented more than a
thousand years ago and saves too much water!

Who invented hydroponics more than 1000 years ago?

Dr. Howard M. Resh: "The hanging gardens of Babylon, the floating
gardens of the Aztecs of Mexico and those of the Chinese are
examples of 'Hydroponic' culture. Egyptian hieroglyphic records
dating back several hundred years B.C. describe the growing of
plants in water." Hydroponics is hardly a new method of growing
plants. However, giant strides have been made over the years in
this innovative area of agriculture.

This is interesting. I would like to see the primary sources for
this to establish if (and how far) the author is stretching the
definition of "hydroponics". Two things come to mind, why did Resh
put the word in quotes, was he indicating that it was a stretch? I
get the impression he was deliberately using a broad definition by
his standards to make a point but not having read the man I can't be
sure.

The second is that if you allow "growing plants in water" to be
hydroponics then anybody with pond plants is doing it and it has
probably been been carried out for much longer than 1000 years. If
you define it as growing plants in nutrient solutions then it seems
hydroponics was toyed with in the 17th century but only got going in
the 20th. Which makes sense as the solutes would not have been
available nor would the knowledge of chemistry. I would be
interested to know if there is any evidence of it in ancient times
by the tighter definition and how they did it.

I will ask the Hydroponic ALLOWING committee to reconsider per your
comments.

Why do you have to be caustic to me? When have I ever said anything about
allowing hydroponics?

I am interested in the history of the technique, maybe you can enlighten me.
Feel free to offer your knowledge and we will have a conservation. If all
you want to do is take jabs at people or ideas that you see as targets then
we won't.
