Mixing the two part hydro juice. Half fill the nutrient tank, mix the required amount of concentrate Part A in the water. Fill the tank and mix required amount of concentrate Part B. Check the instructions on the containers before buying or using either type of nutrient concentrate.
List of the 16 elements all plants need to grow and concentrations in
solution.
| NAME | ELEMENT | PPM |
| Nitrogen | N | 96 |
| Phosphorous | P | 48 |
| Potassium | K | 246 |
| Calcium | Ca | 123 |
| Magnesium | Mg | 48 |
| Sulfate | SO | 412 |
| Iron | Fe | 3 |
| Manganese | Mn | 0.5 |
| Zinc | Zn | 0.08 |
| Copper | Cu | 0.06 |
| Boron | B | 0.5 |
| Molybdenum | Mo | 0.1 |
The 16 elements in the table above are derived by plants from the atmosphere or from minerals in the soil, Dr. Alan Cooper proposed this formulation for his NFT hydroponic system, a typical nutrient solution.
The table below contains
the ingredients to be added to 1000 liters of water, in practice the solution
is concentrated in to 2 parts, preventing loses from chemical reactions.
Fill two 10 liter plastic bottles with water mark that part "A" and
part "B". Dissolve calcium nitrate and EDTA iron in part "A" and the rest
of the ingredients in part "B".
Concentrates
are used by adding 100mls.(cc's.) of each part per 10 liters of water.
The concentration of the final solution can be measured with a EC meter
(electrical conductivity meter),
this reads the conductivity of the nutrient solution.
