DC,
There is an article in a recent Growing Edge magazine on a Colombian
working for one of the international agencies (United Nations perhaps)
who is doing exactly that for hydroponics (no fish). He has fine-tuned
a simple design for hydro growing tables built out of old pallets and
uses media based on the best locally available. He runs participants
through a series of workshops. The end result is a tool to raise
households out of poverty.

Kevin,
Red lettuces in tropical climates are much trickier than in other
climates. I have at least a dozen varieties recommended by members of
this list and seed companies which would not grow red for me here in
Florida.
The best are Revolution (from Stokes seed) which was recommended to me
by William Brown in Hawaii, Cerize/now called Dani (Johnnys) and
Galactic (Johnys). Revolution is the prettiest but doesn't yield as
high as others so I use it in combination with Cerize. It's also the
most expensive, costing over $1,000/# if you buy it in 1 oz packages or
less. I just received 1/2# of Revolution which I bought with the
intention of cooping which brings the cost down to around $400/#. If
you're interested in an ounce of this batch send me an e-mail
privately. One other good source of red for mixes is Bull's Blood beet
greens (Johnny's) which grow the color of burgundy wine.

Think about Melaleuca oil, or tea tree oil. It can work both
therapeutically and prophylatically. You may wish to contact Aquarium
Pharmaceuticals, Inc., makers of "All Natural MelaFix..a New Botanical
Remedy That Rapidly Heals Diseased Fish" Their Technical Service Dept can
be reached at 1-800-847-0659, or you can visit them on the web at

My turn,
While we mostly lurk (usually to busy with fish/plants to write), Jim
Rakocy, Don Bailey and myself find this list useful and occassionally we
find the time to contribute.
John Martin is another researcher in our program with a concentration on
green water tank culture of tilapia.
In case you haven't seen our website for the aquaculture/aquaponics program
at the University of the Virgin Islands Agriculture Experiment Station,
check us out at:
http://rps.uvi.edu/AES/Aquaculture
We have big plans for the upcoming year. 2 new greenwater tanks (200m3) are
slated for construction ASAP. In addition, all of our aquaponics systems
will be getting revamped. We have six experimental recirculating raft
aquaponic units that are having the hydroponic troughs replaced. After 15
years, the wooden troughs (fiberglass lined) have finally given in to old
age. We will replace these with cement block troughs lined with a 30 mil
HDPE liner. Also, we are intensifying our commercial scale aquaponic system
for increased fish production. This will include larger fish rearing tanks,
larger clarifiers, and a reconfiguration of water flow. As soon as this
system is available, I will conduct plant trials on a variety of new crops.
In the past we have produced lettuce as our main plant crop, however we are
interested in improving the profit potential of this system by investigating
other plants. Maybe culinary or medicinal herbs, other vegetables, or cut
flowers. As these trials begin I will keep this list informed on progress.
Fortunately, here in the Virgin Islands we have a 12 month growing season.
All of our crops are grown outdoors and currently I have trials of chives,
cucumbers, melons, celery, squash, and comfrey.
Has anyone ever tried yellow summer squash in an aquaponics system. I am
trying a new variety from Johnny's, ZEPHYR. This is the new yellow
straightneck with green tips. The celery and chives, as always, are
thriving in the system water.
One last comment to Ray Schneider (the tomato-lover-grower). Last year I
was able to produce 500lbs of aquaponic tomatoes from 12 plants in one of
our systems (>40lbs/plant). This was without any addition of hydroponic
nutrient formulas. (only slight supplementation during pH adjustments).
Once you get your fishies, do a comparison (including a taste test). Keep
us informed.
Busy daze,
Charlie

Thanks for the blurb. Still trying to get the reds redder. Talked to my
greenhouse salesperson who confirmed that non-UV treated plastic is good for
coloring up plants. Tells me that non-UV plastic is available for the same
price as treated with the same 3 year warranty. Looking for a plan to
convert part of one greenhouse, but could be a while. Revolution grows like
yours but you just can't beat that color. PS make that Dano (Cerize) like
in Hawaii 5-0. "Book'em Dano"

Contact the Extension Service at the University of Hawaii and get Dr.
Kratky's paper on Non-circulating Hydroponics (also available from
Hydroponic Society of America http://hsa.hydroponics.org), specifically
geared to using locally available re-cyclable items to setup and produce
hydroponic crops. Greatest features, low initial investment, conserves
water, tailored to your locality and it works.
PS I have used free pallets since 1993 to support my hydroponic tables.

Introduction. I'm a development officer for a liberal arts college, doing
marketing, raising funds and thinking about the future of our institution.
Cathy is an administrative assistant (read: runs the joint) for an nonprofit
attached to the college that seeks to provide micro-economic development
projects as part of their Christian ministry. We've thought of hydro- and
aquaponics as valuable tools to use in 3rd and 4th world countries in the
process of not just teaching a man to fish, but teaching him to raise fish
and greens.

On this note, FYI, a short series of articles will be starting in the
May/June issue (which actually comes out in early April) of The Growing
Edge on the same topic. It will focus on this growing system and specific
techniques, crops, etc. These projects have been instituted in Columbia,
Nicaragua, Peru, and Senegal as a test cycle by the United Nations. The
system is slated to expand, but the articles are meant to provide even
wider access to this growing knowledge. The series should last three
issues.

I will post a scan of the test from the CSU Vet service on
my web site under Aquaponics.
After I get it done this evening I will email you the
address for your convenience.
As time permits I will post pictures but we are so darn busy
now that the greenhouse stuff is underway.
Regards,
Marc
