Thanks, Geoff, for correcting my misinformation.

Did anyone attend the recent American Tilapia Association conference in
Orlando? If so, I'd be interested in a brief report.
Thanks, Gordon

The cheapest tanks I've seen are kiddie pools. Aquatic Eco-Systems
(800-422-3939) carries several inexpensive tanks including a 500 gallon
frame type kiddie pool for $64, a 750 gal portable tank for $400, and
galvanized stock tanks with pvc liners up to 19,450 gallons. Just be
sure the materials are non-toxic.

Ben,
Do you know where such small extruders can be purchased and the price
range? I'm interested in home-made extruded feeds not only for fish but
poulty as well.
Thanks, Gordon

Thanks, Paul, for making the digest version possible! Perhaps now I won't get
fired for reading aquaponics postings on the job. I know a little self-
discipline might accomplish the same thing, but you folks have such interesting
stuff to tell. Much of my daily work interaction happens via our email system,
so I can't get away from having fascinating subjects like "Re: Feeding Animal
Wastes to Tilapia" and "Fish Waste Nutrients" in my face all day. I probably
spent 1 - 1 1/2 hrs. of work time each of the last three days reading the posts
whose subjects I couldn't resist.
Remember, the rest of you, that some of us will now be reading the digest
once a
day, so expect a little retro action -- we won't respond to something until the
next day. It will seem like old news to you, but it'll be new to us.
Thanks for all the great information shared on this list. I've learned more in
three days than I sometimes do in a month.

Subject: Basil prices, packaging and marketing.

Hi,
I'm setting up a small NFT hydroponic greenhouse for year-round lettuce
and basil production. Maybe later I'll add fish, but for now I'm
subscribed to the list for the education.
Those of you that produce basil could you let me know...
What is the best market in your area, farmers markets, grocery stores,
restaurants, or somewhere else?
Is your basil dry or fresh?
How do you package your basil?
Where do you get thin plastic clamshell boxes and other packaging for
herbs?
What price do you get for your basil?
What variety of basil do you grow?
Are there any other herbs that are as easy to grow that are equal or
more profitable?
Are there any value-added products that you make with your herbs?
Any information will be greatly appreciated. If you don't want to
answer this to the general list then please Email me directly. Any
direct responses will be kept confidential.
Thanks in advance for any help.
Paul

Erik,
What I am looking for is either the plans for a "less than $100.00"
system students can build. Also, a $300 to $500 system a school or
individual could buy, that doesn't look like it was cobbled together
by a middle school student. We often show teachers and students
how they can build hydroponic systems using two liter soda bottles
or PVC pipe, etc. Usually students need to do a comparison, so
they have to have two systems. Many times parents can't or won't
spend over $50.00 for science project materials. For others, there
is no limit, especially if they see continued use after the project is
over.
