For best results, use warm water to dissolve product. Doggett’s fertilizers are made with 100% soluble raw materials that will form a true solution. Some raw materials are slower to dissolve than others. Keep stock tank covered to reduce light and debris inputs.
MIXING INSTRUCTIONS
Amount of dry fertilizer (oz.) to add to each gallon of water to make a concentrated solution. Check injector setting before use.
NITROGEN PARTS PER MILLION
| Injector Setting | E.C. Value | |||
|---|---|---|---|---|
| Desired N Feed Rate | 1:15 | 1:100 | 1:200 | (mmhos) |
| 50 ppm | 2.5 | 20.0 | 40.0 | .15 |
| 100 ppm | 5.0 | 40.0 | - | .30 |
| 200 ppm | 10.0 | - | - | .60 |
Limit of solubility = 3 lbs. per gallon
IMPORTANT NOTES
E.C. value is the best method to determine fertilizer strength. Fertilizer appearance may vary in color due to variation in raw material size and tracer dye distribution upon the particles in the bag. In solution, color will remain consistent.
Follow these steps for a precipitate free solution.
- Dissolve 130 ounces (8lbs. 2 oz.) of DOGGETT’S HYDROPONIC CLASSIS 5-11-26 in 1,000 gallons of final feed solution. You will obtain the following elemental PPM concentrations:
| ELEMENT | N | P | K | Mg | SO4 | FE | Mn | Zn | Cu | B | Mo |
|---|---|---|---|---|---|---|---|---|---|---|---|
| PPM | 50 | 52 | 215 | 63 | 246 | 3 | .50 | .15 | .15 | .50 | .10 |
- Test to determine if additional Epsom salts required before proceeding. For most crops 50-75 PPM magnesium is desirable in the final solution. If additional magnesium level is required, dissolve Epsom salts into tank. One ounce of Epsom salts dissolved in 1000 gallons provides 7.5 PPM magnesium.
- Dissolve 86 ounces of Calcium Nitrate into the above 1,000 gallon solution to obtain a total nutrient concentration of 150 PPM Nitrogen and 116 PPM Calcium.
