Hi,
I'm looking for an affordable yet workable greenhouse. I came across this.
So, I want to add something else to look at. Take a look at the
"Greenhouse-in-a-bag". I think it is really neat.
http://www.greenhousekit.com/
I still want to be able to offer "summertime tomatoes in winter" in
Wisconsin, so I have ordered some of these as well. Take a look.
http://www.earthbox.com.
I thought I could marry these two together for less than $400 and be growing
some really nice tomatoes.
I know this has nothing to do with our aquaponics list, but there have been
some folks who have expressed interest in greenhouses and, well, since I am
looking too, I thought I would share this. Just for the heck of it.

Hi Gang,
Just wanted to throw this in. I have been looking at many greenhouse
designs, even the "greenhouse-in-a-bag" (see last post). I thought the
latter was cute and could be used but the 3' height could be a problem.
The one that I am "leaning to" is the Weatherguard Greenhouse". These are
made by a company called DGI Worldwide. They come in various sizes, but the
one that I am interested in is: 12'W x 6'6"H x 20'L and has a price of $599.
Now, wouldn't you know, they don't have a website that shows them, but if
you are interested you can contact Adam 'at' dgiworld 'at' transport.com.
He will send you tons of information. It is a very nice packet that shows
all of their shelters and structures. They are very helpful.
Just my thoughts. As usual, I have no vested interest in this. Just thought
someone might find it useful.

Hi Adrianna,
Takes me awhile to get around to everything. Should I just knock on some
local farmers doors and ask if they have barley straw? Or is this something
that has to be ordered? When I finally do get it, do I just put it in a
"say" burlap bag and hang it in my tanks?
While I have you on the line, I was told to keep my nitrates below .25 mg/l.
I'm estatic when I have them below 2.0. (But, I have to admit that the
nitrates/nitrites test is the most difficult to understand. I use a Hatch
test kit.)

I don't think it's rocket science, and prawns are in many ways easier than
some decapods I can think of. So my answer to that is, well yeah going to a
course would be cool, but you are obviously intelligent enough and have the
gumption to jump in and just do it. Maybe just try it on a small scale
using these resources I posted. I would never do freshwater prawns on a
large scale anyway. Just a few thousand pounds for me and my posse per
year. No Tyson scale effort for me here at the homestead....not that it
isn't scalable, but the alternatives to prawn culture that are scalable
(upward) would be my recommendation to the Tysons and the AMDs etc. Still,
I like the idea of FW prawns and Cherax, etc., and plan to grow a few for
the "barby" (sp?) as they say down under.
> On another topic, I'm curious, what greenhouse design have you decided

Well, that remains a state secret. Seriously, I have not settled on a
design..kinda depends on when or whether I eventually buy the additional 6
acres around me here on the prairie.....that will influence my ultimate
scope and dimensions, layout, outdoor production fields, etc........but the
Ohio State reference I posted some time ago is certainly going to be taken
into consideration among my design criteria.
I think I will go with 12 foot eave heights, passive solar vents operated by
those freon piston thingys, evaporative coolers, strong gutter connects that
I can walk on and also so I can capture rainwater as I did in my AgraTech 3
bay system before, and I will have my own automated Aluminet shade system
linked to a light sensor/data acquisition and control board with integration
software that integrates total PAR received per day from a Quantum sensor
over time (kinda like Cornell, but mo' betta for us Rebs here Down South,
doncha know). I might even go crazy and build my own with Rhino Tube
(800-695-7458, http://www.rhinotube.com). Or, I might get inspired by Ray
Bradbury's Martian Chronicles and build a folding flower petal greenhouse
sorta like "Ilya" and her hubbie had on the Red Planet....or not.

Neal,
Check out the December 2000 issue of the Journal of the American Water Works
Association. "Riverbank Filtration, an Overview" by Wolfgang Kuehn and Uwe
Mueller. Abourt 16% of Germany's drinking water sources are taken through
bank filtrate/infiltrate. This is basically subsurface river water, or what
we in Texas call "underflow" of river water, moving through and being
filtered/"treated" by alluvial sands at fairly large scales (dimensions)
compared to running your intake water through a few tons of sand in a slow
sand or rapid sand filtration basin after direct intake from a well or
intake structure in a reservoir. Bank filtration is not completely
effective for all imaginable control criteria, but it is remarkably
effective for many things one wishes to treat for to acheive potable water.
You might be able to get a reprint of the article by contacting the Journal
at journal 'at' awwa.org, or by writing to Herr Kuehn at kuehn 'at' tzw.de. He is the
CEO or research manager at DVGW-Water Technology Center (TZW) in Karlsruhe,
Germany. Their website is http://www.TZW.de.

Oh, by the way, I challenge y'all to go find the Taupon New Zealand "Prawn
Park" website, where they use geothermal energy, I think, or maybe power
plant heated effluent....whatever....to keep the water warm for a little
prawn culture on the sidelines...I am drawing this from memory from about 5
years ago....maybe they have shut down by now.....but go there if you can
find it, and check out the cheap feed.....Mussels, or Clams, or some kinda
bivalve...mixed with Scrambled Eggs! Yum! Makes me hungry for breakfast
right now...So, I gotta go fix some yard eggs for myself right now from just
thinking about that prawn Gruel! I can see makin' cheap shrimp or prawn
feed out of egg protein and marine lipids....man, those New
Zealanders....now that's the spirit!.....you NZ guys are great!....can I
come visit, and maybe stay for a few decades?

Hi everyone.
In the reading that I've done dealing with Aquaculture, I've noticed that
fertilizing the pond is good practice in order to raise the amount of
phytoplankton and zooplankton in the water. Is this practice also used in
Aquaponics? My gut says, "no", but I'm not sure about it.
If you don't fertilize, then what suggestions do any of you have for bumping
up those little critters? Or is it just not necessary?
Thanks!

Mike,
Have you sprayed any oil-based products on these plants? If the
weather is too warm and the sun too hot (above 90 degrees F) the
droplets will work as a magnifying glass and burn the leaf tissues,
leaving black spots.

Carp is a softer and sweeter meat than Tilapia which is a firmer meat and
over all a more tasty fish.

Mike the maggots (a moth caterpillar) mine the inside of the Hyacinths
leaf starting at the water level and working up in a sort of fan type of
damage then causing a rot which attracts fungus nats (a microsmall fly
or fruit flys) which lay eggs and hatch into other fly maggots which eat
the dead spots or create more damage yet. All 3 can be controlled by the
Bacillus Thurencis spelling? quite effectivly. The moth that starts
the whole thing is short living and is most active in the early morning
and in the evening probably due to low light levels and will not be
noticed unless looking for it at those times
The leaf burn is a result of the damage inside of the leaf of the
affected plant
and I don't think the thrips will do that they in general attack the
flowering organs,( such as rose buds up here) but they are sucking bugs
and they can contribute to weakening the plants
Note if the Hyacinths are not native to Jamaica and in the past have
created a problem there your local gov. might have imported their
natural enemies as a control
This typing unifinger has got to end iv got to got it some help

Thanks Mark,
That is a very good point about the cost! Thanks.
What I am looking for is an Herbivore that can be
raised here in OH in a greenhouse during the winter
and yet is marketable to the general public. The cold
water idea is so I can minimize my heat input during
the winter. I spent several years raising freshwater
prawn for research and a couple of years doing
hydroponics and I have a twelve year background in
wastewater chemistry and decided to put it all
together in aquaponics and start a business that I can
also use as an educational tool...I teach biology at a
community college in the evenings. (Good thing I don’t
teach English!)
So, I’m looking for a critter to raise for the
business end that doesn’t require a lot of heat.
BTW, the reason for the “herbivore” is because my
graduate degree involves the study of duckweed and the
fish tanks would give me some place to dump it while
getting some use out of it.
Thanks in advance for any comments or suggestions from
you or anyone else.

Nick the white Amur is a carp its also called the grass carp and get
quit large 3 to 6ft. i belive and comes from the Amur river drainage of
Asia .As for the triploid thing its not a worry You cant name a farmed
food plant or animal that is not genetically engineered some methods are
just faster than others .As for the name Carp use something else carps
are minnows choose river names like Amur or variety names like Israeli
mirror fish or Englisize the latin name call them Crassilis and sell
them as skinnless fillets so they wont be recognized by the prejudice
.Once they are tried they will be sold out . Whats in a name
It used to be that farm boys could make good money trapping a local
fur animal that was extremely popular as fur coats in NewYork by all the
richest ladies. It was sold as american civet or sable (and remains the
best lasting fur) until the Antitrapping types had a law passed and it
had to be called what it is SKUNK big price drop!!
I commercial fish in Alaska for Sockeye Salmon and also get a Salmon in
my nets called Chum or Dog Salmon locally. Its not as red meated as some
of the others but its far superior to any and I do mean any white
meated fish in north america fish markets as to flavor and meat texture
but its called dog Salmon and has no market.I sometimes see it sold as
Alaskan Salmon though.
I forgot to tell you to use Sturgeons another disliked food fish until
lately the
food conversion ratio in them is close to 1to1 or 1 1/4 to 1 and the
growth rate climbs the older and larger they get

So, I'm confused...how does this Bacillus Thurencis ultimately affect the
fish in a closed Aquaponic system???

I'm a stickler for spelling, the correct name is Bacillus
thuringiensis, often referred to as BT. It is a naturally occurring
bacteria that is a disease agent of certain insect pests. There are
several strains of B.t. and they're all quite specific to their target
organisms. For everything you ever wanted to know about BT and which
strain is good for what go to:

I had good luck with Dipel for cabbage loopers but not for army worms.

Ok I have to take the opportunity to ask my question in the hopes that some
kind soul will take pity on me and help me out.
I have been trying to get on THE hydroponics list for months. I was on it
previously and now want to return. I have tried subscribing umpteen times
with no luck, I have called the HSA ..no luck. I have even had a request
posted on the list for me ... no luck.
i understand that you guys are not affiliated -- but I also know that many
of you are on both lists. I think aquaponics is super neat, but I need the
HYDRO list!
Can anybody help?

Hi Adriana!!
No nothing of the sort was done. What is evident now is that these beds
are infested by some type of bug. However what I think is being missed
here in all the suggestions is WHY would the burn be sucessively less in
each growbed after the biofilter? Neal raised a valid and good point
when he mentioned recovery times of the hyacinths .. because Ive been
thinking the same namely, if there were a problem that was topical it
should have been "outgrown" by now!! The beds FURTHEST from the
biofilters are almost back to normal green.
What nutrient excesses or lack could cause a leaf edge browning or burnt
look??
Thanks for all the help so far guys..!! It is great brainstorming with
you.
Sincerely,
Mike

B.T. has no effect on anything other than catapiller types. It will not harm
fish, birds or people ect.

After many attempts to subscribe to the HYDRO list I found this email on the
HSA site justdan 'at' slip.net . It was listed under "questions about the list"
area. I was subscribed in a few days.

I unsub'd and resubscribed last June when I was in California. I sent a
message to:
Listserver Requests
In the body I wrote:
subscribe hydrolist
The last message I saved from that list shows these notes:

Jessica,
I had the same problem and as a last resort I e-mailed the HSA President, Dan
Lubkeman ( justdan 'at' slip.net ) asking for help and afterwards I received an e-mail
from Rebecca from InterUrban WaterFarms ( rebecca 'at' interurban.com ) informing me
that I had been added the the hydrolist.
I hope this helps.

Shumway is not the same company they were when they were in Illinois,
literally and figuratively. But I have ordered seed from them for decades
and not been disappointed. I, too, have taken advantage of their bulk
pricing, especially on seed that would remain viable for more than one year.
Their Goliath silo corn will have people stopping in the middle of the road
and it makes great hominy.

I have just put up a web site. It is a work in progress. Please forgive

Paula, I am not selling anything and won't be for quite some time, so I
hope you don't mind the commercial naming of my site. Just wanted to
