I was reading about high CO2 levels being a bad health
thing. Can anyone address what is a good health procedure to
follow for CO2 enrichment greenhouses?

In Adelaide, Australia there is mountains of the stuff as marijuana is
legalised for up to I think, 10 plants per household for personal
consumption. Obviously syndicates get carried away and caught!
A client who sells hydro equipment told me how they went to the police
auctions and bought all their stuff back for less than their manufacturing
costs and then resold it all through their shops. He said they could
probably turn it over two maybe even three times before it's unsaleable.
Incredible but true.

Hi fishpeople,
I have been stymied by the need for a backwall that is strong,
because the other three sides all have soil behind them, but the one side
(the fence) has no soil behind it, and even though it is a strong fence, it
may give under the pressure of the water's weight. I have been looking at the
metal recycling place for 3/8" metal, 22' long, 3' high to brace with rebar
or something dug into the ground.
In the meantime, maybe someone could help me decide how much pressure a pump
would need to pump up about 10' thru a 1/2 inch tube to the the tubes on top
from which the water will spill thru holes over the vertical 2 liter
popbottles (720 vegetable sites) which will hold the plants over the
trenches. Or better, do I just need some timer device to hook it up to, and
to experiment to see how often it needs to soak the roots per day. Greenhouse
is 22'x7'x7'.
Also, I'm thinking of waterplants to supplement the fingerlings which I'm
still at least a few weeks away from being ready to buy. ATTRA sent me some
good info, if anyone needs some inspiration and some details. I'm really glad
to be a part of the aquaponics movement.
Good fishing,
Tom O

If you know your flow needs out of the pump in gal per min
an exact punp match can be made.

If you set up a test planting bottle and run the desired
flow rate into it for a minute you will know how many gal
per min per bottle. Take the total number of bottles and
multiply by the amount you measured over the timed one
minute test and that is your gallons per minute.

If I were a law enforcement agent I would consider the equipment
paraphernalia and would destroy it rather than risk it getting back out
and into cultivation again.

Hello all,
I have been working quietly over the past few months constructing a
miniature version of the Speraneo's aquaponic system. I also have been
reading many of your posts for many months to learn as much as I could
before I began my first foray into Aquaponics. Thank you for all of your
advice and thoughts. Below is a brief summary of my efforts to date.
First off, I live in a small house in a neighborhood that does not allow
greenhouses. Therefore I needed to keep this system as small as I could to
be unobtrusive. I also wanted to use this as a learning experiment and
therefore one of my goals was to keep the cost down by constructing most the
components myself or scrounging for second hand supplies. The parts I did
purchase new were the pump and the timer. I also decided to purchase a good
quality pump and timer since these are the keys to making this system work
and I could reused them if I decided to build a bigger system.
The growbed is constructed of scrap 2x8s (untreated) and 3/4" plywood picked
up from a friend in the construction business. It is 3ft x 5ft x 8in and is
held together with metal angle brackets. I used marble chips as grow
medium instead of river rock since I found a clearance deal I could not pass
up (30 lb bag for $1) There are six bags in the grow bed. The growbed is
lined first with a heavy plastic rip-stop plastic tarp with two layers of 4
mil plastic on top. This may be over-designed but I figured it is the
engineer in me.
The growbed sits on four cinder block columns each four blocks high.
Underneath is a 55 gal glass tank that I picked up at a local pet store who
was getting rid of some old equipment ($40). I have a 700 gal/hour pond
pump that pulls the water up to a grid system constructed of 1/2in plastic
tubing that floods the growbed. At the low end of the growbed I installed a
4" plastic drain pipe that drops the water directly back into the tank.
This return action also aerates the water for the fish.
I use a Cyclestat II timer that floods the grow bed every 15 minutes for 3
minutes.
I purchased 30 Nile tialpia from Living Waters. Great people and very
helpful. The fish cost only a few dollars but the shipping by two-day air
was $50!! My wife asked if the airline would give me the frequent flyer
miles and the peanuts for the fish! I put 22 fish in the 55 gal tank and
put 8 fish is a separate standard 15 gal aquarium (just in case I really
messed up).
In the grow bed I put a mixture of plants and seeds:
Four marigold, three basil, and six pepper plants
Lettuce, basil, and salad cress seeds.
The plants and seeds were put in a few weeks ago after I cleaned and
initialized the system. The plants look a little weak but are still alive
and all the seeds are sprouting. The fish are growing nicely. I need to
get a small scale to track their growth.
All of this is enclosed in a 5ft x 6ft x 6 ft mini-greenhouse outside that I
built from scrap 1x2s and 4 mil plastic sheeting. When it starts to get
cooler here in Atlanta I plan to add furring strips and another layer of
plastic to help insulate it during the winter. I will probably need to add
a tank heater to keep the water temp in the tolerable range for the fish and
plants.
All total I have spent just over $350 (primarily the pump and timer) so far.
I will be glad to accept recommendations or suggestions for improvements.
I do have a question. In one post someone suggested barley straw to control
algae growth. Where does one get this from?
Thanks,
Michael Merriken

Michael,
I've read that regular straw works as well. The kind you get in bales.
Go to a feed store and see if they let you sweep up what has spilled in
handling, put it in one of those small mesh bags for laundering delicate
lingerie and float it in the tank.

Add some fish emulsion to your system, a little at a time, this will help
your microbes and your plants. I've also added a little liquid kelp now and
then. Fish don't care. You don't need a timer, your need a float switch.

Debra,
I'm only growing greens and lettuces for mesclun which are harvested
young, so bolting is not an issue. The heat has a significant impact on
germination and yields, with production dropping by more than 50% this
last month. I wouldn't dream of growing head lettuce because of heat
and humidity. ECHO has a couple of varieties which they recommend for
the tropics, if you're interested. Basil does well and a few of the
oriental greens like Mizuna and Tatsoi are doing OK. Other varieties
have come to a screeching halt.
I looked into solar pumps on the web and found them to be exhorbitantly
expensive, over $1,000, so I scrapped that idea quickly.

Tom whatever you decide on using you will have to anchor it to the opposite
side. Meaning if you have a wood wall on the open front every four feet you
will need to crossbrace it to the opposite side , and make sure the opposite
post is well anchored. Otherwise your one wall will fail.
X-----X-----X-----X
X-----X-----X-----X
The Back row of X's represent posts sunk down into your dirt back wall. The
front wall represent posts secured to your wall that you build. Now you will
need to connect the front and back X's across the top to secure the front
wall to the back. This then will hold against the water pressure on the
front wall that is backed up by dirt.

Is there a reason besides aesthetics you want to get rid of the algae.
Tilapia will feed off of it. U.V.I> has been developing a system that uses
greenwater ( algae ) and have had spectacular results . I on the other hand
have been trying to get algae to grow in my tanks especially the fry tanks.

I use the battery operated sump pump setup from Simer and
add a solar powered charging system whenever I have a solar
customer who needs a pretty good flow without much pressure
for the lowest price.
