Hi,
I know of a grower in Florence, Oregon that is growing Wasabi
hydroponically, but I can not recall the name of the company. There have
been several write-ups about him in the local agricultural paper: Capitol
Press as well as the Oregonian I believe.
If I can come up with the name, I'll post it, but this should give you
somewhat of a lead on someone growing it.
Sorry I don't have more information than that.
Jennifer

I believe Growing Edge did a feature on a wasabi grower in New Zealand
about a year ago.

What will you sell me a start of this duck weed for. It may be a little
late in the season but I need to fine a source, I could put it into the
green house.
Thanks John Hays

Jon
I don't need to sell you anything! Tomorrow Sat. I will ship priority mail
a box with some duckweed seed in it. The pond I got this from had almost no
"duckweed" left in it due to the cold temp. but I scooped out a bunch of
seed and I have it in a 30 gallon aquarium in my greenhouse with a light on
it. Will send a zip lock bag with some seed to you. If you feel inclined
you could reimburse me for shipping, if not send me some information on
anything, for I am new to aquaponics.

DOES ANYONE USE A CEMENT TANK FOR TILAPIA CULTURE?
AND DOES SOMEBODY KNOW A DESIGN FOR AQUAPONICS USING ONLY ONE PUMP FOR
BACKYARD USE?

TO WHOM IT MAY CONCERN
DOES ANYONE HAVE AN IDEA OF A TANK SIZE FOR 500 OR 1000 STOCKING RATE OF
TILAPIA AND RESPECTIVELY THE SIZE OF GROWING BED SUITABLE FOR IT?

Well it depends on several things
1) are you going to add extra aeration ?
2) are you going to go with high stocking rates with injected oxygen ?
The rule of thumb is 1/4 pound of fish weight for non aerated tanks up to
1/2 a pound depending on feeding frequency , temperature , feed type , etc..
That said I just specked out two types of rectangular tanks
3 feet wide X 30 feet long X 4 feet deep = 2692 gallons
4 feet wide X 30 feet long X 4 feet deep = 3590 gallons
now what type of media are you going to grow your plants in
NFT - nutrient flow ( gutter type )
Raft - plants floated on styrofoam panels
Gravel beds - plants grown in gravel in flood and drain
Sand beds - plants grown in sand in either flood and drain of continuos
flow
Depending on media type will depend on how big your growing system will be
Also depending on what you plan to grow will effect how big your grow area
will be.
