Sure, his name is Hal, 719- 395-2696. We're using him as a consultant for
our project now. I'd like to know the outcome of a "meeting of the minds"
between he and you guys.

Chris, we use the PT-9038 800 gallon tank in our operation, along with six
PD-4902 trays (grow beds) per tank. What size system were you considering?
We've been pleased with the durability of the products, and certainly
recommend them. Tony has been especially helpful in working with the
various requests we've had over the years (but don't let him know, it might
go to his head).

We have two greenhouses at our facility that we raise Tilapia in for Bead
Filter research. We would like to install a small aquaponics system in
conjunction with our fish systems. Just to hobby at first! I am relativley
space limited to start. Can I use one tray to begin and then add from
there? My green houses are clear poly so light is not a concern.
Chris

Adriana,
you are the second source I've heard that has experience with
Miracle Gro. Now I am intrigued. You have been a wealth of
information in the past, thanks. Could you share any more
info about Miracle Gro ?
I've been using a product called Power Plant. It works well,
a bit pricey though. Just a couple of questions I have are,
what's the salt do, why the frequent water change, what about pH,
how well does it scale up, and could you mix a common blend that
would work for a wide range of plants ?
Thanks again
Rick

Hi Rick,
Unfortunately in the case of Miracle Gro I'm just passing along
information that was posted on the hydro list. It's an option for
people who don't have access to reasonably priced hydroponic
nutrrients. The guy who did the original posting and uses it himself is
called Joel at MUDDTOO, don't have a last name. Lets see if I
can answer any of your quetions:
> I've been using a product called Power Plant. It works well,
> a bit pricey though.
A: Most of the hydro nutrients geared to hobbyists are very expensive
so if you can get Peters of Miracle Gro to work for you it sure sounds
like a great alternative.
> what's the salt do,
A: The nutriehnts are all salts
why the frequent water change
A: Hydroponics is a bit like voodoo, you don't know exactly what's
going on. The reason for the water changes is the assumption that the
plants are consuming different nutrients at different rates and at some
point it may get so unbalanced that it is detrimental to the plants. In
the absence of doing costly chemical analyses to measure the composition
of the nutrient solution you just do a periodic changeout.
, what about pH
A: Different plants are happy at different pH's. Most greens do well
in the range of 6-7, which is where they can best absorb nutrients. Too
high or too low will inhibit their ability to take advantage of the
nutrients even if it is present in the solution. A good cheap way to
check your pH is to use a swimming pool test kit. It only goes down to
6.8 but if you keep it no higher than 6.8 your plants will be happy.
A: Sorry, haven't tried it but I suspect if you need to scale it up
it's time to move up to commercial hydroponic nutrients which come in
25# bags for 5-11-26 and 50# bags for calcium nitrate.
> how well does it scale up, and
A: Yes but you might sacrifice yield a bit. For instance I can grow
tomatoes in the same nutrient as lettuces and herbs but they won't be as
productive.
could you mix a common blend that
> would work for a wide range of plants ?
I hope this helps.

Hello Rick,
I'm interested too! Who was the first?
You're right, Adriana does give out good advice. I use MiracleGo because it
works good and I'm usually a little lazy, not wanting to put more work or
money into something then it needs. It isn't the cheapest way to go but I
can pick up a box of MiracleGro anywhere, anytime.
If you like to mix your own then here are some numbers. Both MiracleGro and
Epson salt provide an EC of about 500uS for each scoop (tablespoon) in five
gallons of water. So 2 scoops of each in five gallons measure out at 2000uS
plus the value for the water. The water here in Southern California is also
about 500uS, so the total is about 2500uS. This is about the bottom limit
for tomatoes, and okay for peppers. Lettuce and cauliflower like it lighter,
somewhere around 1500 - 2000. The strength of the nutrient, for plants, is
dependent upon the weather and these numbers will change some throughout the
growing year. Stronger in the winter and weaker in the summer.
I may have generalized or simplified the nutrient change cycle some. The
correct answer is to change the nutrient when you have added the same amount
of makeup water as the tank contains. At my house in the summer I add about
three gallons of fresh water a day into a 20 gallon tank for the tomatoes.
So, in a week I've added about 21 gallons into a 20 gallon tank and it's time
to change it out again. The winter use is a lot slower, usually growing
lettuce and cauliflower only and they don't drink up a lot of water.
Try some and have fun.
Joel
