Carlos, all i can say is this particular list friend was anything but bored by what i
think is THE fundamental question on aquaponics i.e. how come you can successfully
grow plants such as tomatoes [heavy feeder] and lettuce [light feeder] side by side
in the same nutrient when hydroponic chemical salts fail to do this.
Teds answer i suspect is more than just theory as it makes good sense, to me at
least.
Lets have more, more.

The discussion is far from boring and is the reason I'm on this list.
I'm an engineer and have been dealing with machines for the past 20
years. This whole "new learning" (biology) fascinates me. If I can get
10% of this I think its been a good day. What I'm trying to do is
develop a "feel" for how this new biological machine I'm about to build
is going to tick. And you guy's are definitely giving me that "feel".
Any lister that feel this boring can just hit the delete key like I did
with the whole computer/virus thing that went on a few weeks ago. So
bring it on and let me read some more words I had no idea existed in the
english language.

The trouble with good ideas is that they soon degenerate into a lot of
hard

sounds)

Hey Carlos,
No excuses necessary. I, personally, look forward to any input that you may
have. I think your English is probably a lot better than most of our
Spanish.
Take care my friend..Steve

Dear Adriana and all the other friends of the list:
First of all my apologies. I'm sending a Table that I'm compiling for my
new book but I didn't translate it. I expect nobody complains.
Many times I see that some people is worried by poor results using
aquaponics with certain crops. When time ago I was asking about measurement
of conductivities in the fish ponds and in the water running back I had not
answers in the list. I understood that maybe nobody checked this factor.
Lately Steve talked about tomatoes. And Adriana said:

Adriana is right. There are vegetables that grows better at low
levels of
nutrient concentrations (lettuce, basil, etc.) other requiere medium levels
and a third group needs high levels (tomatoes, beens, etc). Of course, don't
expect good results using aquaponics without nutrient salts suplements for
vegetables in the third group.
Like Adriana I'm not having yet an aquaponic system. Also I'm an
hydroponic oriented fellow.
In writing my second book (in Spanish) on "the ABC of hydroponics", I
was searching around and I ordered in a Chart the compiled values that I was
able to find. I feel it will be useful as a reference for many of you. For
others maybe will be nice to know about.
I tryed to insert the original chart but I was unable without to
breaking the rule on inserts. However, the chart was copied directly from my
manuscripte such it was prepared and it is in Spanish. Since there are not
too many words in it, translation will be very simple with a
hand dictionary or with the Babilon system. My excuses.
Regards to all of you,
Carlos
