We are growing tomatos in a large scale hyproponic system. We are
looking for a "bloom" nutrient for these tomatoes that comes in "one
part" and thus requires no mixing (ie, most hyprodonic tomato nutrient
formulas come in two or three different parts which must be mixed
together). Name that one-part nutrient, give us the technical info on
it, and the money is yours.

Since you did not specify that this nutrient must be available
from any particular location, I will go ahead and provide you
with information about just such a nutrient, which is available
from the UK.

Lightsite Hydroponics in Devon, England produces a brand of
hydroponic nutrients called IONIC:

"IONIC is a Single Pack Nutrient Solution for Hydroponic
 cultivation stronger and more potent than Formulex and
 designed for high performance. Until IONIC first appeared,
 all serious Hydroponic nutrients were supplied as twin packs.
 This is because the essential elements have a tendency to
 react with each other in the concentrate producing insoluble
 precipitates."

"Growth Technology has been formulating and manufacturing
 nutrient solutions since the early 1980?s and we have always
 had the goal of producing a Single Pack solution without any
 residue. The project has been ongoing for several years and
 has involved countless experiments and many setbacks.
 Finally however our senior chemist Carl Barry has developed
 a completely new process of nutrient manufacture that uses
 a series of tightly controlled reactions to produce large
 complex molecules which contain the essential macro elements
 needed for plant growth in a stable and highly soluble form.
 This technical breakthrough has many important implications
 for the Hydroponic grower."

The bloom nutrient you require is called IONIC Bloom:

"IONIC Bloom is dedicated to the fruiting and flowering stage
 of plant growth, containing enhanced levels of Phosphorous
 and Potassium, the elements required for development of buds
 and flowers."

Directions for use:

"For GROW or BLOOM, add IONIC to tap water at the rate of
 10 mLs per Litre. Target EC for most applications is
 2.0 mS/cm2. Stir thoroughly. Check pH of final solution.
 It should be between 5.8 and 6.3. IONIC has a stabilised
 pH and it should not require correction. If adjustment is
 needed use Growth Technology pH UP or pH DOWN and follow
 instructions carefully."

All of the above is from the same page cited earlier.
That page alone is a goldmine of information of value
to hydroponic growers.

I sincerely hope this is a workable supplier for your needs.
