I would think that maybe taking sand from public beaches or somebody's
private property could be considered illegal. When I was growing up in
Colombia my father had a dredging operation to extract sand and gravel
from a local river. This was used for construction and also for making
concrete blocks, posts, etc. I suspect you can go to a construction
supply place and /or concrete fabricator and buy legal sand and gravel.
Now if you're looking for "legal" and "free" that's another story...

possibly abuse them?

3) Sending ATTACHMENTS to the list. Sending an attachment to everyone,
while you may think it contributes to the discussion, only bogs down the
server and costs many people time and frustration in downloading data that
they may be unable or unwilling to open anyway. Attachments can contain
viruses, so many people make it a general policy not to open any attachment
from an unknown source. So if you have an attachment you think it would be
worthwhile to share, please just post an announcement and email it
PRIVATELY to those who ask for it, e.g. "Hey, I've got a great .GIF of some

Hi Ron,
It was my understanding that (when the weather is cold) this type of GH
takes in air from outside to pressurize the envelope but exhausts it
_inside_ the GH - carrying a good(?) percentage of the heat that made it
through the inner skin back inside. You get an extra temp gradient along
the length of the envelope (assuming inlets/outlets at opposite ends)
but both ends roughly balance out and as long as you have good internal
air circulation, an internal gradient (along the GH) is avoided. Does
this sound right, wrong or doesn't make enough of a difference to worry
about anyway?

I too am on the search for sources of wasabi. Searching is best done with
the name Wasabia japonica. I have two to offer, others would be greatly
appreciated.

Offered by Redwood City Seed Company, Box 361, Redwood City, Ca. 94064
Phone (650) 325-7333. This website Copyright © 1998 and 1999 by Craig and
Sue Dremann., co-owners.
Anyone who loves sushi has tasted the green wasabi or Japanese horseradish,
the popular indigenous condiment from Japan, which is made by grating the
plant's finger-sized roots. Wasabi is becoming popular here in the United
States too, with prepared wasabi sold in tubes, canned, or as dried root
powder. We are offering the live plants for planting, and it has taken us 24
years of searching to be able to bring you these plant!
Plants are perennial fresh-water stream sand-bar and rock-bar plants. The
roots are easily grown in a plastic container with drain holes in the
bottom, filled with a mix of coarse sand-box sand, perlite, and 1-2"
diameter drain rock. Plants need to be kept at all times in FULL SHADE,
especially protected from the afternoon sun in summer or plants can wilt.
The sand-perlite-rock mix is best kept cool and moist, ideally around 60-70
degrees F. Plants may need to be watered once a day in summer to keep the
sand-rock mix moist but they do not like standing water around their roots.
Check at night for snails or slugs on leaves. We do not recommend using
snail poison, just hand-pick. DO NOT TRY TO GROW INDOORS, we have had 100%
failures from indoor attempts.
Plants need to be fertilized periodically; and if young leaves start
wrinkling, they need a shot of lime. We sell one year old plants, and will
need at least one more year's growth before roots can be harvested for
grating to make the condiment.
As plants grow, they will flower, make seeds and new seedlings will appear
in the pots with your mother plant. By the time you are ready to harvest the
original plant, you should have young seedlings taking its place.
PLANTS $35 postpaid, only shipped within the U.S.A.

Hi group! 2 questions:
1) Does anyone know of sources for Wasabi?
2) - In choosing a variety of watercress to feed the Tilapia, does anyone
know if they only like regular watercress, or other varieties like
"broadleaved cress", or "Upland cress"?

When I install double poly roof glazing I always try to do it in such a
manner that the inflation fan moves a minimal amount of air. We always
install the poly-loc glazing bars so they fit as tightly as possible to
create an envelope that doesn't leak. Of course in practice this never
happens. Air always escapes around the poly-loc at a small rate. Sometimes
small holes are inadvertently punched thru the glazing during installation,
larger ones are always patched. My installations are usually on 30 by 100
foot gutter connected bays so sometimes holes do appear even when care is
exercised. I never intentionally provide an outlet for the inflation blower
because I prefer having an envelope that is relatively firm. I believe that
here in southern New Mexico an envelope that is inflated to a higher
pressure is preferable. During periods of high winds, which happen
regularly, the bays that are inflated at a higher pressure seem to absorb
wind gusts better than the looser envelopes.
In most of our house we minimize interior air temp gradients by using
horizontal air flow fans that automatically operate whenever the exhaust
fans are turned off. This eliminates cold spots and reduces the incidence
of fungal infections.
But to get back to the issue of heat lets look at an example. A typical
inflation blower is one such as a Dayton model 4C440. I have one of these
in each 30 x 100 foot bay. This blower operates in one house that I
measured at 0.14 inches static pressure. This blower puts out 60 CFM at
free air conditions and deadheads at 0.60 inches static pressure. At the
operating pressure of 0.14 inches static pressure the output is about 56
CFM. If one doesn't beat this to death mathematically, a simplified
equation for the heat loss would be as follows.
Heat loss to outside = 56 ft3/min * 0.075 lb/ft3 * 0.243 Btu/lb deg F *
(70-10)/2 deg F * 60 min/hr = 1,837 Btu/hr
The 30 deg delta T is rather arbitrary, I just assumed an interior temp of
70 deg and an exterior temp of 10 deg. The reason I divided it in two is to
assume that the envelope air temp may equilibrate at the midpoint between
the inside and outside temps. This also assumes that all blower air escapes
to the environment which is not necessarily the case.
To put this number in perspective I looked at my previously calculated
heat loss coefficient for the greenhouse. It is about 173,000 Btu/hr at
this outside temp. The roof heat loss due to outside blower inlet air
amounts to just over 1 % of the total. The size of this loss becomes
insignificant relative to other things such as infiltration of cold outside
air which is nearly always the largest single component in the greenhouse
heat balance equation. This is directly related to construction practices
and quality of weather stripping and sealing.

Vive le gnome libre!
We have a new, and very serious threat to the well-being of homeowners
around the globe.
According to a short report issued by the Agence France-Presse (which
was reprinted in several major newspapers, including Canada's National
Post), a new faction of society is resorting to spectacular tactics like
mysterious midnight kidnapping raids to draw attention to their call for
freedom.
They call themselves - I swear - The Garden Gnome Liberation Front. The
Front's aim, apparently, is to free gnomes from domestic captivity and
return them to their natural woodland habitats. Earlier this month,
some 143 garden gnomes were discovered lined up in front of the city
hall in Sarrebourg in eastern France. Previously, another 73 had been
found in a schoolyard.
There is no doubt that the gnome's plight is a desperate one. Captured
by the thousands every year by slave rings operating under code names
like "Wal-Mart" and "Target," the poor little critters are torn away
from their homes and families and placed on shelves in garden centers
throughout the world - ironically, right next to products like
"RoundUp."
After weeks of torture (things like flourescent lighting and mall music)
designed to break their spirits, they are sold to homeowners who force
them to stand motionless, for seasons at a time, in their gardens. An
ignominious fate if there ever was one.
No wonder then, that 11 of them were found hanged last year, in what the
French press called a "collective suicide." The accompanying note
explained that they were "leaving this cruel world... to join the temple
of oppressed gnomes." (The temple of course, being a central tenet of
their religious faith, Gnosticism.)
Why should homeowners be concerned? Because if you've ever studied the
rise of , oppressed accessories throughout history, you'll know it's
only a matter of time before the gnomes start using more aggressive
tactics. Indeed, there's already talk of setting up a freedom fighters
world headquarters in Nome, Alaska. Improvements in cellular technology
will soon create units small enough for these creatures to improve their
communications networks - enabling them, in effect, to phone gnome. And
it worries me that the GGLF started in France: a country known for
things like revolutions, Bastille storming, and guillotines.
Frankly, I'm beginning to wonder if I'm not already a victim of a quiet
campaign of horticultural terror. Several flowers in my garden have
died mysteriously this year, and at least one of my stepping stones has
gone missing. (I'm just waiting for it to turn up as a little bag of
pulverized gravel accompanied by a demand note).
Several new weeds have been "introduced" into my lily patch. A friend
of mine living on a ranch in the prairies has reported that he stepped
on a rake twice this year and swears that he wasn't responsible for
leaving it out on the lawn.
This means there's at least one activist gnome on the range. Maybe even
a whole group of radical gnomesteaders.
But it's the widespread effects of a potential gnome uprising that are
truly frightening. If they succeed, they set the stage for further
upheaval. We'll have pink flamingos, stone toads, various half-naked
Greek statuettes and even garden gargoyles clamoring to join the gnome
front. Entire bands of garden creatures wandering loose in the
countryside, causing trouble. Gnomads, if you will.
After that, who knows? Stuffed animals everywhere might be inspired to
crawl out from under the bed to freedom, with a battle cry of "there's
no place like Gnome!" on their faux-fur lips. Heck, there are enough
captive Beanie Babies alone to start up entire regiments. And perhaps
the Royal Doulton figurines will start thinking of restoring the
monarchy again.
So take this as a warning my friends: gnomes may be cute, but they are
also revolting. Hide the hedge clippers and lock the implement shed at
night. Report any suspicious movements to the proper authorities.
Be ever vigilant, because you can bet they're not going to stop until
they're gnome free.

Hi group
just a question. Do aquotic plants, such as watercress, use ammonium
rather than nitrates. I heard this is a biology lecture the other day.
Is it true? If it is can you use a bed of watercress or large algue
instead of a biofilter.

JB, mining in an area where dredging as Adrianna said is not allowed
causes serious erosion, landslaides and slippage of buidings near rivers
into the river valleys. Sand from say the mouth of rivers, etc delta and
so on can cause the backup and flooding of low lying areas, hence mining
permits are granted.
Removal is good in this case.
Abuse in Jamaica is like this...Im poor... cant be bothered re the
Babylon system, permits and all so out come the dredge, pay a guy 500$
to bring a few Caterpillar buckets of sand from a fording home for me,
and I sift at leisure, build my low cost house.
Next Hurricane season, we can tell. I have seen beautiful waterfalls of
my childhood been reduced to gurgling green algae streams by removing
aggreates from this river lower downstream...In my lifewtime then, I
have already seen the destruction of great recreational areas on the
river, how much so will my unborn sons and daughters say?
