Congratulations Emmett. Oh the lessons we learn! I'm trying to ration
the tough lessons to about one a month, that's $$$TOUGH. Thank god it's
a new month. By the way, if you have a need to insulate any tanks, Home
Depot has a great material that looks like silver Star-Wars bubble wrap
which works great.
Back to you, Rocky, I know that when I've ordered sand for beach-sized
sand boxes in the past you could specificy that the product be washed.
I suppose you could request (and pay) for it be double or triple washed
for an aquaponics installation. It's a lot easier for them to run their
dump trucks under the sprayers than it is for you to schlep it (that's
the New York half of me talking technical).
Tell when I can start marketing your tomatoes.

Ted,
Where have you been hombre? It's been mighty quiet in your neck of the
woods. Will your watercress grow in hot weather? I had always assumed
it wouldn't be happy in the sub-tropics.

An 87 year old horticulturist visited my greenhouse and wondered if
something he called Chicken Granite could be used as an alternative to
my perlite.
Emmett, I believe you had to import your gravel since it's not native to
Florida. Is anybody familiar with the granite? My first thought is
that I assume that it is a crushed stone which might have sharp edges.

Stuff sounds like the aquatic equivalent of kudzu. Not sure how I like the
way that
sounds. Somebody tell me it can't stand a freeze and I'll feel better about
planting
some here.

I have been wondering about poultry grit myself- it comes in several
different sizes and is clean so it rinses quickly. The edges aren't
dangerously sharp when handling it. It cost about $2 a 50 # bag from a feed
store. Turkey girt #2 isn't as common and can be ordered if needed. It is
about pea size. Chicken grit is closer to perlite or aquarium rock size.

Chris - did you ever get an answer to this? Is it common to use
sporekillers in your system? Exactly what type system are you using?

Jim,
You are safe. No freeze tolerance. It does not even like cold but
above freezing weather. It is a tropical that loves it hot, wet and
humid, and sunny. Adriana would have to be more careful if she had it
outside. I think I have heard that it is on the noxious weeds list in
Hawaii and at least some parts of Florida.
It is my daughter's favorite green vegetable when stir-fried.

Hi: I'm a first-timer on the list and am slightly overwhelmed at all =
the information. I am very interested in aquaponics on a commercial =
basis. Can anyone point me to financial modelling information, software =
or spreadsheets??? for aquaponics systems???
As well, I don't think I recieved any information on managing my =
subscription to this list. Is there a web page for getting instructions =
such as temporarily stopping the subscription, or getting the postings =
in a digest format?? Any information would be appreciated. Keep up the =
good work. Thanks in advance,

Watercress grows quite well in Hawaii, but it seems they use free flowing
cool mountain water to get the job done.

This sounds like a good plant for my experiments with feed lot run-off. I need
something which grows well and is good for something other than compost. If
this is
used as bait fish feed, I think it would be ok even if grown in waste water of
questionable quality (high e-coli content, antibiotics, etc.) which I
wouldn't want
to use for human consumption, even if twice removed.
Anyone done any yield comparisons between this and duck weed? Dry weight
wise, duck
weed doesn't produce nearly as much fodder as most people seem to think.

Howdy, mam'e.
Ive been running around doin stuff, but I try to keep an ear to my favorite
discussion group when I can. "Life is what happens while your busy making
other plans"
Watercress grew pretty well in the hot weather...this was last year...I
tried several varieties...I like the taste and the growth....but I think it
needs to be marketed separately...sort of like marketing your single product
of beet leaf.
See ya.

Hi All,
This may of course sound silly but has anyone tried using
electronic bug repellent machines? I have heard of some
work with ultra sonic, ion generators, electromagnetic
field generators etc. and wonder if any have tried anything=20
like this? I wonder if a very safe to humans low amperage
charge in grow beds might might annoy the little bugs enough
to make them go elsewhere? If it would work the plants could be
sprayed with a little water to make them surface conductive.
Just a thought ...

I recently tried to order a package of the Chinese Water Spinach from
Richter's (www.richters.com) and was told it was illegal to ship seed of
this invasive species from Canada into the US.
