I agree with Raul Carlos. 
Mushrooms are something that I have been interested in
and seen growing
quite well, even under the growbeds so to speak.
There is a new and growing number of mushroom farms
here in Jamaica. If
you notice in my mail re alternative posts I am also a
member of the
group mycology 'at' egroups for all those interested.

Raul, could you give the list a DEFINITION of GEO
HYDROPONICS please??

I would also be interested in more information re this
issue if
possible.

Bruce and Carlos have you ever seen this site.
http://www.cropking.com/mushroom.shtml ??? 
Its very interesting to see their setup!!

Carlos,

I disagree. I, for a minority of one, am interested in
this. I contacted
Crop King and they sent me a plan whereby I could grow
mushrooms for a
measly $1/2 million dollars.

If anyone has any info on this, I'm sure that Andrei &
I would be
interested.

I have a basement where I think I could grow
mushrooms.

Thanks & I apologize Carlos

Dear Andrei:
You cannot grow mushrooms using neither hydroponics
nor aquaponics.
Mushrooms need special compost to grow.
Some mushrooms does not require light. Other needs
some lighting.
What variety are you thinking about ? Agaricus,
pleurotus, shi i take,
boletus, morells, 

3000 varieties?

This is not the proper list to consult. The subject is
out of the interest
of most the list members.
If you want more information I can give to you at your
own mail.
Also, there are many people can help you in USA. Check
Penn State University
Mushroom Lab or the American Mushroom Asociation at
Kennet Square, Penna.I
think they will help you, even much better that
myself.

Carlos

PS: If you do not like headaches, mushrooms aren't for
you. I know by 15
years experience.

HEY GUYS!! (Promoters of the November Conference)

Wake up!! Let the list members know a little
information about the November
conference. People are contacting me asking me for
information. I want this
to be a success. You didn't even ask me to give a
talk. I can talk all day
about things not to do.

I will be glad to help in promoting this, but I don't
want to "carry the
ball". Come on Folks, help us all out.

Paula (I feel I can speak for her about this.)
wouldn't mind you guys
promoting this. This is going to be a great thing, but
you guys have to
SPEAK OUT and let people know what is going on.

If you want me to promote this, I will.

TO THE PEOPLE WHO HAVE REQUESTED INFORMATION:  Gordon
Creaser (a tremendous
resource person); Sam Bass, Charles Johnson and on and
on will be presenting
the program. It is from Nov 6th through Nov 9th. It is
going to be
TREMENDOUS.  To get further info, contact:
cwjohnson 'at' graham.main.nc.us.

I'm sure that if you offer to boycott the program,
they may even offer me a
position to speak. I mean, I'm sure that all of you
would love to hear from
"socially insensitive" Steve

:)   I mean, I am
such a shy person and
all.

Seriously though, this is going to be a great event.
I'm even dragging Bruce
Schreiber along with me
.kicking and screaing
.but
he is coming along. A
real nice meeting of all of us nestled in the
beautiful hills of NC. Not too
bad a picture!

See ya'll there

NEWS RELEASE

AQUAPONICS COURSE

Aquaponics interest is increasing globally in response
to more emphasis
on resource management, sustainability and waste
management. It involves
combining of aquaculture and hydroponics for mutual
benefit. To help meet
the demand for instruction, a practical course in
Aquaponics will be held in
Bryson City, NC, November 6 - 9, 2001.

Lecture and AV presentations will include components
of aquaponic systems,
fish and plant selection, balancing fish/plant
production for efficiency and
optimum
yields, utilizing old farm and other buildings, small
scale pilot projects,
systems design, natural pest control, meeting organic
standards, economics,
specialty
markets for higher profitability and accessing
technical assistance and
information.
Sites of interest, including a thriving commercial
hydroponic lettuce greenhouse
operation and a watercress production operation
utilizing trout farm
effluent water
will be visited.

The lead instructor will be Gordon Creaser, who has
been involved in hydroponics
for over 40 years and travels world-wide as an
aquaponic consultant.  He is well
known for his down-to-earth practical advice.  In
addition, owners of
several successful aquaponic facilities will share
useful information
concerning the design and operation of their systems.

Kris,

I have been interested in anaerobic digesters ever
since
I was a wastewater treatment operator.  We had 4 of
them
in our plant.  We used the methane produced to run the
boiler that heated our buildings.  Sometimes we used
it
in our huge blower engines that supplied air to the
aeration
tanks.  We couldn't do this too much though because
the gas 
wasn't clean enough
.sulfides and things caused
problems
with the engines
.great boiler fuel though.  They
stopped
calling the processed sludge
.sludge

it became
bio-solids.

this link had some interesting notes on farms using
them here.
China has millions of them
.makes you wonder.

PS
.(sorry, I hit the send key too fast)

Imagine a digester setting beside a row of greenhouses
supplying warmth to the rootzone year-round

at the
same
time converting plant waste to a valuable fertilizer
and
soil amendment
.fueled only by the fish and plant
waste you
are generating
.BYE BYE propane heaters (that heat
the
air rather than rootzone).  Hydronic heating is the
way to
go
.boilers fueled by digesters are the way to do it.
(In my humble opinion).

Date:    Sat, 21 Jul 2001 10:16:28 -0300

Raul, Mike and Steve:
     It is not my intention to enter in polemics. It
is nice to know
everything you say but

I WAS TWENTY YEARS LOOSING
MONEY WITH MUSHROOMS !
     I was a member of the MGA (Mushroom Grower's
Association of England), I
read every magazine and book I found on the subject, I
went to Japan and
Taiwan to the 8th International Congress, I had the
Proceedings of all
Congresses from Nš 1 to Nš 10, I was in contact with
Penn State, I know
about most of the illness and pests on growing
them

.etc. etc

but

I LOST A LOT OF MONEY. I know the day by
day about the growing
pains of a mushrooms grower. You bet it!
    Raul say:
> The first book I read about hydroponics, was
HIDROPONIA - CULTIVO DE
PLANTAS SIN TIERRA,
> written by G. O. Huterwal - Editorial Hobby, Com. e
Ind. - Buenos Aires -
Argentina
    Huterwal was a pioneer. I feel his book was the
first writen in Spanish.
That was also my first book about hydroponics. In the
Introduction of my own
book, I mention his contribution to hydroponics. Yes,
he explained there as
Raul say:
> In that book, the author has a small chapter about
hydroponic mushrooms,
and he gives the
> formulas of the solution he used.
I tried as Raul do,
> I tried it, but with no success.   Even so, the
author of that book made
it.   So, there

also without success. But, I was involved more and
more on the subject.
Exciting subject without doubts !.
> As I had studied mushroom production in the
traditional ways, the idea
came imediately,
> after reading that book:  -  Why not produce them
hydroponically?
Same as Raul, I liked the idea.
Until I knew more about mushrooms growing, how they
get their food, how they
decomposed cellulose materials, etc

One day, in spite of a good advise against it of a
fellow at the American
Mushroom Association, I started my mushrooms
enterprise. There I knew all
the pains. Fighting and fighting, I was living 15 to
20 years. Living ?.
Finally, one day, 5 years ago, I closed the doors.
In my thinking, maybe some day it will be possible to
produce mushrooms
commercially by ORGANIC HYDROPONICS methods but only
UNDER HIGH
TECHNOLOGICAL APPROACH. One of the battles to play in
order to get it is
fundamentally competitors macro and microorganisms. If
somebody get it, that
person will be the new Bill Gates.

I think this is already too long for our list. Lets
follow out of list if
you want it. Please let me know.

Let me pipe in here in case Raul is off-list. (
California-style
energy shortages in Brazil have led to government
madated rationing
and blackouts which make computer time even more
precious and ISP
shut-downs frequent.)  I believe that Raul would agree
that the gas
needs to be cleaned to be usuable in a lot of
applications.

Regarding the sludge, Raul's process uses a unique
combination of
aerobic and anaerobic digestion which produces a
sludge-free
biofertilizer that can be used for hydroponic or soil
fertilization.
In order to produce a sludge-free ebnd product you
need a uniform
manure or effluent input which is free of cellulose
fibers.  So the
issue of animal housing, such as caged hens vs.
free-range are
important.  In aquaponics you have a consistent,
uniform input and the
solids can be settled out of the effluent and run
through a
biodigester.

.great boiler fuel though.

When I hear the term "biosolids" (doesn't it sound
innocuous?) I think
"municipal waste biosolids" with all of the possible
toxic inputs that
go through a city sewer, including illegally dumped
chemicals and
industrial output.
> They stopped

it became
bio-solids.

I am not 100% sure but, I think that Senhor Martins is
willing to give us
the secret to growing mushrooms successfully in an
aquaponics system. I
don't know enough about growing mushrooms to ask

but, you do so please ask for the rest of us. I know

Mark,

Thank you for that link on biodigesters. I agree with
you on their
importantance if we are going to go to the next step
in sustainable food
production. It won't be long before they're trading
shit on the New York
Stock Exchange, and why not, it is just unrefined fuel
and organic
fertilizer. As you read last night I asked Professor
Martin about setting
up a commercial biodigester. 

My mission is to set a closed eco-system that will
provide all the food,
fuel, electricity, heating and cooling necessary to
supply a neighborhood
sized community with everything it needs to live
comfortably. I think
that aquaponics is a really fantastic discovery but,
since my goal is to
grow all of the food necessary to sustain life
happily, I think that it
will be imperative to seperate the fish from the
plants so that heavy
feeders like corn can be grown without hurting the
fish with the

need it. Also, if
someone wants to increase yield by adding CO2
injection, it is also
important to raise light and nutrient levels to
maintain the balance that
is mandatory in crop production.

I know this is not the sustainable agriculture or

discussion
off-list. If anyone else is interested and Raul, his

Hi Carlos:

I can imagine how much you suffered with mushrooms.
I felt that on my skin.
But I have never been a real producer.   Only a
researcher.
The only thing that I want to tell, is that it is
possible to produce them Hydroponically.

And as I said, I don't reccomend this for a beginner.
Many researches have to be done on the hydroponic
system, but one thing I can tell you.
It is more ease to produce them hydroponically.
The first you headache you eliminate is with the
preparations of the compost.

Hello Kris:

I have never been out.   Everyday I read the mails
from this wonderful list, but not
allways I have sufficient knowledges to answer some
questions made.
I have been involved with the development of a small
biodigester mainly for philantropical
purposes, and I finished the drawings only some 15
days ago.   There are 67 drawings in
the complete project.
I am now writting the handbook that goes with the
drawings.
Contact Adriana Gutierrez or Melvin Landers about
that.

Yes.   Just unlink the systems.   Filter the feces and

Adriana, 

I received a post from Melvin Landers this morning, in
which he mentioned
that you have experimented with numerous organic
hydroponic solutions. My
first question is, how long will a biofertilizer last
before fermentation
makes it unusable? Secondly, have you had any contact
with a product
called Metanaturals? It is an  certified organic
commercial hydroponic
solution. Please expand on these subjects when you

On a note though, regardless of the type of operation I would certainly have a complete water analyses done on the source water as that could be treated prior to filling tanks or raceways. Fluorocilicates can be easily removed by nanofiltration. Chromium 3 which is commonly found in borite and serpentine and reverts to chromium 6 via an oxygen or DO exposure and may be found in fish. This brings to mind another quick search I'm going to jump on tonight. I think redox may lesson total chrome via a sulfate reducing iron media. Hmmm, ya get one little question and you end up spending the whole night pouring over a few dozen sites and digging up an aquatic chemistry text off the shelf.

For you to understand the system, I would invite you to visit my site at http://www.hydor.eng.br In two words, geo-hydroponics is similar to aquaponics, but the two biomasses involved are unlinked. Instead of using fishes (aquatic animals), we use terrestrial animals, whatever they are. The word "geo" is used to denominate terrestrial animas, just like in aquaponics where "aqua" is used to denominate aquatic animals > Since going for a walk through the Biosphere 2 12 years ago I have had an idea > that I've been working on in my head using live stock penned over the > fish tanks such as Guinie pigs, rabbits,ducks,chickens and bees to > change the waist stream a bit for different plants and have the > mussels,fish and redclaws and turtles separated were necessary to clean > up the extra feed and manure using a marsh in a living mudbed tank in > line with the regular S-S type system could a sand mushroom bed work in > such a system on a different timing loop. I believe that such a system would not work, at least for mushrooms. A mushroom is not a plant. It behaves completely different from these ones, and it is adviseable for those that pretend to deal with those "incomplete plants", to know something about their physiology. For instance, they have no leaves nor chlorophyl, and so, they can not break carbonic gas to produce sugar, and from this one to have a source or Carbon. Generally they produce enzimes that decompose cellulose and they use it as a source of Carbon. So, a mushroom needs "liquid carbon", and they can get it from organic compounds. But the molecules of these compounds must be very small for them to absorb them. You have a series of those organic compounds in the soluble humus present in the biofertilizer. On the other side, carbon dioxide is a need for a plant, but it is a poison to a mushroom, though mushrooms "excrete" lots of it. That is why in the ambients where you cultivate mushrooms, you need a high level of ventilation to clean air from that gas. Agaricus, for instance does well in temperatures around 16 or 17 centigrade degrees, and a relative humidity of 80 to 90 %. These conditions are quite different than those needed for plants. I'm saying this in very simple words, as things are more complex than this. But regarding you ideas, some years ago I made a very interesting experiment. I mounted a series of NFT channels over a vermicomposting bed, to take advantage of the carbon dioxide hexaled from it. I got 32 to 37 % more productivity with lettuce, and 40 to 42% more with cabbages. I think that this endorses your ideas, but not with mushrooms. Paula's system also takes advantage from a similar situation, as fish feces decompose in the growing beds, hexaling carbon dioxide too. Regarding you idea, it will work quite well, if you join all the feces of your animals in trays, for instance, and then carry them to a biodigester. But NEVER USE THE FECES TO FEED YOUR FISHES OR ANY OTHER ANIMALS, AS SOONNER OR LATER NATURE WILL GIVE YOU THE EXANGE. In my opinion, that is a crime, though in US, and even in Brazil, many people feed fish, cattle and hogs with manure. But this is changing, and at least here, some laws will prohibit that practice untill the end of this year. Excuse me, Paula. I and my long messages.

As I work in the Natural Gas Process Industry, thought I would pass on a note of caution with regard to the unwanted part of Bio-gas, i.e. Hydrogen Sulphide. Believe the topic is relevent to the list as there are quite a few people involved in the discussion. Following up on the comment on toxicity of gases, one of the most Toxic gases known is actually the Hydrogen Sulphide ( H2S )component of Bio-Gas, that needs to be removed. Smells like rotten eggs, but dont be fooled by this as even in low concentrations, the olfactory sense of the brain quickly becomes overwhelmed and loses the ability to smell this gas. This then makes Hydrogen Sulphide "odourless". Hydrogen Sulphide is Heavier than air. Explosive Range of H2S is Extremely wide, from 4.3% to 46% by volume. It is Highly soluble in water and liquid Hydrocarbons at elevated pressures, and will be released as a gas again at ambient temperatures ( use this concept for designing your H2S scrubber ! ). When Burnt, H2S produces another toxic gas, Sulphur Dioxide ( SO2 ) Toxicity range :- ( PPM , Parts Per Million ) 0.003 -.02 =Odor Threshold Above 10 ppm , Toxic, wear Respiratory Protection Below 10 ppm, Quickly Deadens sence of smell Above 300 ppm, Considered Immediately dangerous to Life and Health ( IDLH ) Above 500 ppm, Attacks Respiratory sence in brain, causes loss of Consciouseness within 15 mins. Above 700 ppm, Rapid loss of consciousness and death. Above 1000 ppm, Immediate loss of consciouseness and death. Biogas can easily amass concentrations within these ranges above. Also bear in mind, gas scrubbers as would be needed to remove the H2S, usually have a recyclable liquid as the medium. This recycling process can quickly produce abnormally high concentrations in the area, such as in a containment area, or building associated with this process. H2S, as has already been mentioned, is highly corrosive. Even stainless steels are not immune. Vessels, pipework etc really needs to be 316 stainles, or Monel. However, even these high dollar materials are not immune, H2S can produce Sulphide Stress cracks in 316 stainless Vessels. Carbon Steels do not last very long at all !

Yes, it is quite toxic in very large quantities, and it is dangerous as it is a combustible gas. > They recommend that ethanol and biodiesel are a much better products to > make from biodigesters. Your views on this subject, please. Ethanol from a biodigester? We produce here ethanol from sugar cane. I can't say anything about biodiesel. I heard about the process, but I have had no time to read about it.

I'm not sure why our utility department never installed a scrubber. I wondered at the time (1980's and early 90's when I was there and they still haven't). For those who may wonder what we have been talking about and want to learn more, or anyone that wants to see a great low-tech system check out this link .great site. http://www.roseworthy.adelaide.edu.au/~pharris/biogas/beginners Scroll down to the bottom and check out the link to Building a Poly Digester. Some may think a Bio-Gas discussion is off topic here.If you do, consider that plants and fish generate waste. Waste can be (and SHOULD be) converted to energy. It can be thermal energy like methane .or caloric energy such as larvae and redworms that eat the waste and turn into fish food .or valuable fertilizer that replaces the enormous energy consumed by industrial fertilizer production. Waste to energy is a concept that many of us try to utilize. Steve, thanks for the note on hydrogen sulfide! It nearly killed me once in my early sewer maintenance days. That being said, don't let it scare any of you. It can be removed. It is good to be aware of it and understand it though. fun thread .take care everyone.Mark | Message 43 Subject: Re: Does anyone do this: From: kris book Date: Sat, 21 Jul 2001 22:35:14 -0600 Raul, Pardon me but, my brain always has one more question. Do you have any idea how much mushrooms can raise the CO2 levels in a confined space? As you probably know, there are about 300 ppm (parts per million) of CO2 in the air we breathe but, plants thrive with up to 7 times that amount. It seems to me, if mushrooms create a lot of CO2, then we should build a mushroom room near the greenhouse and a storage tank there also, so we could hold the CO2 until we are ready to feed it to the plants. kris | Message 44 Subject: "Kool Ray" liquid shade From: dreadlox 'at' cwjamaica.com Date: Sun, 22 Jul 2001 00:05:52 -0700 Dave could you expand a bit more as to what this is supposed to be and what this was related to?? Is this a paint thingee that one uses on greenhouse glass? Mike.
