Wow! Thanks for all the great suggestions for building and/or buying less
expensive growing beds. I stayed up late just to get the daily digest, and
really appreciate the work that a number of you went through to respond to
my query.
Dreadlox Mike -- I bought a Oase Pond-Air 30 aerator from
http://www.plumbingsupply.com/oaseair.html for $60, and am very happy with
it. It consumes just 28 watts, and sets up a gentle upwell of water with
zillions of tiny bubbles. No more worries about the fish dying off at night
when the algae stops photosythesizing. BTW, I searched high and low for the
best price for this pump, and Plumbing Supply had the best deal. They were
also very professional to deal with. (Standard disclaimer -- no connection
other than as a satisfied customer.)
To whom ever was discussing settling tanks, I recently visited Biosphere 2
near Tucson and spent a lot of time at their aquaponic demonstration. I
seem to recall a circular settling tank between the fish tank and growing
beds that is tangentially injected and centrally flushed -- it looked to be
a very clever and effective design with the fish poop solids suspended in
the middle right over the central drain.
Ted -- I have to add South Texas Ruby Red Grapefruit and Avocado to the
Favorite Fruit List, not to mention the coffee cherry pit (roasted of
course)
. ;)
Take care, y'all!

I think you may have made a slight error in the assessment of the bubbles not
oxegenating the water if not could you explain why.

I know a lot of us seed our growing beds using the "broadcast" method.
I justn found a great little gadget at Target which works great for
this. It is a stainless steel Spice Shaker, Furio brand (Target
label) which has an adjustable top with about 4 different size
openings. It works great for a variety of seeds ranging from the
teeny tiny to the great big ones. Now I'm looking for clear glass
jars with the same size opening. My plan is to store each seed
variety in its own jar. All you need to do to seed is swap out the
top for the shaker top and you're done. Then on to the next variety.

Your DO and pH are in good shape, but have there been any sudden
changes? What is/was the water temperature?
The 0 reading on ammonia and nitrite are also more than a little
puzzling in a tank with that many fish
Have you made any extreme water
changes? Have you been feeding?
Sorry, but more questions than answers from me today

Ted,
When you purchase apricot trees, try to get a variety that has a chill hour
(winter hours between 32 and 40 degrees F) requirement that best matches
your location. The reason apricots bloom to early is that they get their
chill hours to soon -- they think its spring before it is. Most apricots
only need about 200 to 300 such hours. I think you get around 800 (check
that, though)
Good luck,
Jim

Good morning Jim,
Due to the tank being outside and with the rainy weather my temp has been
anywhere from 17 deg C.to 21 deg C. There has not been any water change until
last night, I did not know what else to do so I changed about 50 % of the
water. Like I said I noticed a few fish turning on their side and darting
off the second day I had the fish. Water quality has been steady with out
any real changes other than temp.
The fish were eating pretty good up until two days ago.
Can you explain what would cause fish to swim on their side?
Thanks again

I've also heard "old-timers" talk about putting blocks of
ice on the ground around the apricot trees in early spring
to delay bloom by keeping soil cooler.
When I was a kid in Illinois we got great crops MOST years,
but here in SE Colorado it's pretty iffy - they bloom too
early and then we get a late frost/freeze. Even on the
western slope they don't get a crop every year.

Fish that tend to do the swim on their side and darting off thing is caused
by parasites and they are scratching their bodies on the sides of the tank
when they do this. Ectoparasites generally will not cause mass mortality
unless they get on the gills or cause severe lesions on the fish and
secondary bacterial infections will occur.
To start with I would suggest doing a skin and gill scrape and looking at
them under a compound microscope and go from there.
Good Luck
Todd

Stocking density to water quality reading seem a little off though you
didn't mention exactly the type of water treatment you might be using other
than effluent going to grow beds. Outside of an introduced parasitic
problem that may have been on one or more gills of the catfish. Did any fish
seem to be gasping for air (so to speak) at the surface for any days
preceding mortality? Indication of low D.O. though erratic swimming on their
sides may certainly be a gill fluke? Is your makeup water treated or checked
before blending. thermal shifts, chlorine can certainly effect you stock? Is
your makeup water municipal or well source?

My beds made from cement board screwed to rewood 2X2s with stainless screws cost about $125 for

perhaps it's time for Paula to post the price of poly tanks beds if your time fabricating is
worth anything at all it makes the poly tank look cheap and poly tanks are light and easy for
one person to move.
My poly tanks bowed out at the side When filled with graved so I used 1" pvc pipe with a cap to
make a spreder stay in the midle. I did this on the cement board boxes too.
I used loose stack contrete block for a base and filled the base with sand or peagravel for

Subject: mushrooms
From: "Carlos Arano"
Date: Tue, 29 May 2001 20:07:49 -0300
Bruce:
If you like to live happy, please follow my advice: stay away from
producing mushrooms !!! Leave others to do it.
Until now, there is not an hydroponic method to grow them. Most
mushrooms needs to decompose organic matter such as cellulose. They eat
nutrients to grow from the products obtained by this decomposition.
Hydroponic solutions are all inorganics. Mushrooms doesn't like them.
But, if you are really interested in growing mushrooms and you think I
am not right, my new advice is:
If you are thinking in growing mushrooms in hanging bags you should grow
Pleourotus ostreatus, the oyster mushroom. It is one of the easiest to grow.
You will need wheat straw as a basic
material and very few additives as gypsum and calcium carbonate (maybe
sterilized soya meals if go further). Sterilizing the whole preparation is a
need. You can do it cooking it but it is not good.
I was doing Agaricus, Pleourotus and Shi-i-take for more than 15 years,
enjoying a lot and suffering also a lot with them, paining, enjoying,
paining again, etc
. I lost a lot of money with them and with the banks.
Stay away from them !!!!
In spite of my good advice you still wants to grow mushrooms, you can
contact the Penn State University, Mushrooms Lab. It is one of the best
places to get information and spawm. They, and God, can help you.
Regards,
Carlos

Thanks All for the suggestions on shade cloth.
I have a lot to try that might work for me.
There was one question on the "Greenhouse". Its just
a welded angle-iron structure with a pitched roof.
The roof is covered in glass ( my cheapest glazing materials here that
is clear ) to keep rain out of the solution.
The sides of this structure are covered with very fine
Nylon Netting to help control insects.
>From some of the replies I had, can I assume that the roof
does not actually have to be clear ?
Could it be an opaque white corrugated vinyl sheet ?
I would still need shade cloth probably, but this would be a cheaper
solution than the Glass roof I have at present.
Thanks again for all the good ideas. Thats gonna keep be busy for
another month !

Kris and Steve,
Swampo coolers work best in low humidity environments such as Arizona.
In muggy humid tropical environments you can get about a 5-7 degree
drop in temperature from them. One other consideration regarding
evaporative coolers. My growing neighbor has a 6,000 sq ft greenhouse
with an evaporative cooler. She says it uses about 400 gallons of
water every 2 hours. Ouch! I prefer to apply all methods of passive
cooling (shadecloth, ridege and side vents, etc.) before getting more
aggresive.

Hello All,
I Just finished reading an article in the magazine FUTUREGROW, issue 8.
titled Commercial Hydroponics in the U.S.A
The author, Gordon Creaser claims that he is working with growers in
Florida that are selling cut Basil for .70c a half ounce bag, and
producing 1lb of basil per sq ft of grow space per month. That works out
to $22.40!! a month per sq ft. Is This guy dreaming or did I just die
and go to haven.

Sunagro I believe are a high pressure sodium there claim to fame is
producing more yellow and red spectrum light (good for flower) than metal
halide. I used a similar light and had the same problem of long internodel
length. I tried all sorts of reflective material had best results with mylar
which I still use. I If you don't want this expense use flat white paint (not
ceiling white) wall to wall. This will reduce the internodel length if you are
not currently using reflective material. Metal halide lights are generally
better for early growth of plants by mixing metal halide and high pressure
sodium lights you get top results. There is a newish light on the market its a
new generation metal halide (400w) I am giving one a go at the moment they are
amazing. I have the shortest internodel length I have ever had so short infact I
think ive gone a little overboard so I use it in a day about cycle with a
sonagro. The last thing I would to say is that 1000w lights are generally the
most inefficient 600w seem to be the best closely followed by 400w.
Hope this helps
High regards
Mark

Does the 2"X2" in the bed create a small dam and therefore a stagnate
area in the bed? Have you seen any bowing along the 8' sides?

Bill, sorry I did not fully explain the 2"x2"x4' is in the middle under the
bed, not inside
I have seen a very small amount of bowing of the
plywood.but not the 2"x6"x8'. if bowing should occur just add a few cinder
block piers. as needed.
Hope thsi helps.

While I have not met Mr.Gordon Creaser, he is a very knowledgeable
consultant in AQUAPONICS,HYDROPONICS as well as AQUACULTURE and writes for
the AQUAPONIC JOURNAL also has a questions and answers in the Journal. When
you see the results of AQUAPONICS, it makes you wonder why more people have
not followed that line for employment.
