I have an 800 gal. poly tank that had to big holes punched in the side with a fork lift. (that
is why i was able to obtain it for free}
I laid it on it side in the sand, hole down and warmed the edges of the hole good with a touch.
Then I heated strips of poly until they burned on there own and let them drip into the hole I
wanted filled. It is ugly but it holds water. (Only atempt this stunt with good ventilation.)

I posted this in October 2000, I think
Maybe related to what we are talking about
The pore water in ebb and flow aquaponics systems using 1/4 pea gravel is in
a "closer" equilibrium (not a perfect equilibrium) with the culture water,
due to the frequent and complete flooding and flushing. This is unlike
irrigated soil culture, in which you might see 1.5 times the EC in the pore
water in the soil profile compared with the EC of the irrigation water being
delivered to the soil. Now this is interesting because one of the ways that
irrigation with higher salinity water has worked in sandy soil outdoor
culture is to irrigate very frequently...I won't get into that very much
except to suggest that you check out an article that appeared in Scientific
American on using high salinity water for irrigation....naturally the
Israelis have worked all this out already.
Since nitrogen and phosphorus and potassium are taken up by the plants (and
certainly to a perhaps significant degree by the biomass of the bacteria
living in the microzone around the surface of the gravel....sometimes this
microzone is referred to as a "biofilm" by the microbiologists and
bioremediation scientists in the crowd....also, you may have an earthworm
biomass develop, which feed on the residual sludge and sloughed off biomass
of the bacteria...another nutrient "sink").....then you should see a kind of
steady state develop over time as you harvest the fish and plants out of the
system and put the feed into the systemThis is not a perfect steady
state, however, by any means, since many aquaponic systems are designed and
operated so very differently....and so it is hard to generalize here.....but
especially since not all ingredients in the feed are assimilated by the
various nutrient sinks (the various biomass "compartments" of the system) at
the same rate. Therefore, if you have sodium chloride in the feed as an
ingredientand if your system experiences considerable evaporation from
the surface of the grow bed and the surface of the water in the culture
tank, you may see a gradual increase in salinity over timeover a
period of a dozen weeks or a dozen months, or even more, depending on things
like the fish density and the feeding and growth rate of the fish , and the
feed ingredients, of course.....

Dear Ted:
Thank you very much for your kind answer. I think the points are clear from
both parts.
At this time I think that it is enough. Lets avoid to bore our list friend's
with our personal discussion.
Anyway, it was nice.
My best regards,
your friend,
Carlos

Agreed, Carlos. Agreed.
It seems we work toward the same goal.
"Why? Why?".... is not only very important, but also Very Motivating!
Sincerely,

I found that most plants flower just fine if they get the same day length
as September 21 or 22 or what ever the first day of fall is in your
area and then shorten the day length by about a half-hour after 2 or 3
weeks

I don't remember much being said about foliar feeding on the list. I
played with it for 7 years, tinkering all the time. My final conclusion
was, that less is more. I found that the underside of the leaves took up
more nutrients and that the smaller the mist size the better and to stop
spraying just before the leaves became saturated. I also found that the
bat guano you talked about made the best foliar tea. The 50 year old kind
for vegetating and the 100 year old kind to aid in flowering. Worm
castings made a good all around tea.
Some tea huh,

That is the direction I am going, yes, indeed.less is more for foliar
feeding.
Seems we are working along in the same direction.
Nemostasis, there, kris, or what have you there.
