DEar listmanager:
i think I managed to subscribe to your aquaponics list but something went
wrong with the welcome message. I do not have instructions to participate at
the list instructions and particularly on how to review earlier messages. I
would appreciate your help.

The design I'm working on for our next generation greenhouses uses roller
tracks, as
found in many warehouses and air or truck terminals. You've probably seen these
rails with roller skate wheels mounted all along them? What I have in mind is a
return trough along the wall with a sump at the end, and overhead plumbing
for the
water flow from the fish tank. This way you can fill all but a center path with
plants. One person can easily move the 2' x 8' trays along the track. The
tracks I
picked up surplus are food grade stainless from a refrigerated warehouse so
should
resist water damage and be durable.
Jim
PS: anyone with recommendations for flat panel solar collector suppliers, please
email me. I'm in the market for enough to heat 22,000 gal. year round.

Hi Jim,
Interesting idea. Will the rollers impede walking the length of your
trays or are they on the ground? If so does this mean your beds are
down low and harvesting would be more difficult? What happens when you
need to get to a tray in the very middle of a 100-foot long greenhouse.
I assume you would need to move 25 trays to gain access? Would an
occasional buffer-aisle give you more flexibility? After all one 2 foot
tray is simple to move, 10-20 grows old.
How will the effluent from the overhead supply line get to the growing
trays, via flexible hoses with enough slack that will permit movement 2
feet in either direction?

Hello All!
I was asked by Dr. Takeda, Research Horticulturist
at Appalachian Fruit Research Station, to post a
complete citation for the paper that we posted
earlier, which I am happy to do.
The paper was published in Acta Horticulturae Vol.
439. Pp. 673-676. 1997. The proceedings of the
3rd International Strawberry Symposium, held in
Veldhoven, The Netherlands, April 29 - May 4,
1996.
Dr. Takeda also informed me that the variety
Camarosa has produced more than 2 pounds of
marketable fruit from November to May and they
sold them for $ 3.00 a pound to local restaurants
and B & B's this season!
Thanks for the update Dr. Takeda! We look forward
to learning more about how you do it!

Dan,
Is that 2 pounds of fruit per plant over a 7 month period? At this
yield and these prices are they feasible? What do you figure the
production costs to be?
Does Dr. Takeda have any more current research that he can share with
us?

The trays will be mounted so that the tops are 3' high which will mean
stepping over
a track ~2' high to get between trays. A 100' section of track would make
for a real
problem moving the trays, but I'm figuring on 20X30 foot sections since
that's the
simplest (cheapest) size to build $/sq.ft. 416sq.ft. of plants compared to my
current 320 sq ft in the same size greenhouse, which amounts to 3 extra 4x8
tables
per greenhouse. You could use the same spacing arrangement in a longer
greenhouse.
Just figure a 4 ft lane every 26 ft. or so. That way the trays are
manageable. At
the old Hyde Park warehouse one person could shove around several tons of frozen
food surprisingly well. My layout would amount to having 8'x26' grow tables.
I leave
4 feet down the middle now for my yard tractor to drive down the middle
pulling a
wagon. I have some old airport baggage carts I use for hauling loads indoors
behind
a small tractor or ATV.
The effluent will feed directly from the pipe into the open end of the trays
with no
direct linkage.
Jim

Can we get Dr. Takeda on the list? Also do you have a source either online
or in print for Acta Horticulturae? There are many interesting hydroponic
articles I would like to read.

I'll second that for lettuce. The media that does get into the system is
minimal and may act as nutrient buffer.

Hello Everyone,
Does anyone have any suppliers for the 288 plug trays? Web sites if
possible, I would like to see what is available to the growers.
How bout price/20 lbs of lettuce? I have a friend that runs several
resturants. He is willing to buy 20lb cases of lettuce from me if the
price is right. If I remember it correctly, he gets his lettuce for $14
for a 20lb case.
Prices for bell peppers also wanted if anyone has any to share.
TIA,
Brian Gracia

Hello Again!
I am building a greenhouse control system that will run off an old 386 I
have laying around. If I can get it to the level of service I forsee for
it, I would be willing to share the code and circuits diagrams.
Does anyone have particulars that they want to control, wish to control, if
only I could's? Let me know and I will see if I have not already planed
for them.

Thanks, I will check the catalogs. I do require certification for shipping
to Hawaii for ecological heath.

Here in Hawaii because of shipping costs we get $24/20lb ($1.25/lb for
Romaine in bulk)

You're right and that's it. We find those do well for us and haven't
bothered with finding others. I'm not sure which part of Florida your in
but all get pretty hot/humid. Where I'm at we're sub-tropical with daytime
temperatures seldom exceeding 86F but humidity upto 100% (so it seems).
We're actually growing the kales, mustard cabbage and Mizuna in beds. They
seem to last longer and generally grow better in the ground. Arugula is
another one that didn't like my hydroponic setup and is grown in the ground.

Hi all .
Nobody has responded to the best practice method for running 300,000litres a
day of fish nutrient water through an aquaponics set-up.
Anyone have some good ideas?
