A little something for you all to marinate on.
product called
AgSil 16H which is a brand name for Potassium Silicate. This
is a mined mineral compound and it's molecular formula is K2O3Si and it's the Si
(Silica) that is water soluble. This is the exact same compound used in the Dyna
Gro Pro-TeKt product (and others like Silica Blast, Rhino Skin, etc. - no
mystery at all)
The link is to Custom Hydro Nutrients and they sell the
base compounds for those who mix their own hydroponic nutrients. Their price for
a single pound is only $12.00 and .70 grams to 1 gallon of water will give you
an uber safe application mix ratio.
Potassium Silicate is 'approved for
organic food production' because mined minerals cannot be 'organic' or
'non-organic' - they can be 'approved' or 'not approved' or have 'limited
application approval'
So there's one bottle down and it's on to liquid
'seaweed' and other weird claims.
I know of only 3 true liquid
kelp
products from around the world:
KELPAK - located in South Africa and they do have a very
unique product because the 'juice' in the
kelp
fronds is pressed out by machines and it does not use powerful Alkaloids like
the powdered products (Maxicrop, et al.). This product is usually available in 5
gallon jugs and is priced around $40.00 per gallon. This is a favorite with
hydroponic bottlers because it's crystal clear just like water meaning that it
won't interfere with their color schemeatic.
KelpGrow - located in British Columbia and they grind the
kelp
into a slurry (specific particle size) and they they use what they call
'microbial inhibitors' to extend its shelf life. I didn't bother looking at what
that might mean - could be anything from Phosphoric acid to Citric
acid.
Powdered
Seaweed
Extracts - this is main one found in most garden products. Maxicrop is a big
player. The
kelp
is processed with chemicals (Potassium or Sodium Hydroxide) which renders this
plant material into a black powder - powdered
seaweed
extract. Notice that these products are never identified as 'powdered
kelp
extracts' and that has to do with an international treaty dating back to 1950
when Stephenson first introduced this new concept to the world.
Kelp
is
kelp.
Seaweed
extract is
seaweed
extract.
Maxicrop mixes the powder with water and usually adds some
Soluble Potash to bump up the 'K' numbers for the ill-informed.
Any of
the retail 'liquid
seaweed'
products are powders and if the largest manufacturer (Maxicrop) tosses out some
real crap can you imagine what is coming out of Asia? South America?
You
want to find
Kelp
meal because this is like Alfalfa meal in this regard - it's minimally
processed. The
kelp
fronds are layed out in the sun and basically dried and cured. Then it's cut,
sized and bagged. Very little (tiny amounts) of
kelp
meal ever hits the dirt compared to the amount used in livestock supplements,
HABA products, research in medicine.
Kelp
meal is easily sourced at places that cater to horse owners - feed stores or
sometimes called farm stores. Almost all of the
kelp
meal in North America comes out of Nova Scotia (Acadian Seaplants, Ltd.) in 50
lb. bags. The price should run between $75.00 - $90.00 (depending on how hard
you're getting stabbed).
But consider this - 2 oz. will turn 5 gallons of
water into
kelp
meal tea with all of the 'things' you want (Alginic acid, Mannitol, IAA, IBA,
etc.) plus when you're done brewing the tea, the 2 oz. of rehydrated
kelp
still retains about 50% of the 'things' you wanted in the first place.
You can add this to a new batch of soil, toss it into a worm bin,
top-dress plants in your outdoor garden.
