Controlled Environment: Growing hydroponically with Jack’s

General Hydroponic growing with 2 part

Jack’s Professional Hydroponic Formula has been designed to serve as a base foundation for hydroponic growing. It can be manipulated in such a manner as to provide virtually any combination of nutrient levels desired, providing the highest availability to plants, due primarily to Jack’s proven ability to remain in true solution over long periods of time.

Jack’s Professional 5-12-26 Hydroponic

Follow these steps to obtain a precipitate free solution

  1. Dissolve 130 ounces of 5-12-26 Hydroponic in 1000 gallons of final feed solution. You will obtain the following elemental PPM concentrations:
    ElementNPKMgSO4FeMnZnCuBMo
    PPM5052215632463.50.15.15.50.10

    For the most effective use of the Hydroponic formula, it is essential that the nutrient content of the irrigation water being used is known. These figures are then taken into consideration and should be added to the distilled water figures as quotes above. This is of special importance when figuring the need for adding more Magnesium (Mg) and Calcium (ca) depending on the needs of the crops being grown.

  2. Dissolve any additional Epsom salts desired into the above 1000-gallon solution before proceeding. For most crops, 50 PPM Magnesium is an adequate level in solution. To increase your Magnesium levels, dissolve 10 ounces of Epsom salts in 1000-gallons of final feed solution to obtain 7.5 PPM additional Magnesium and 3.00 ppm Sulfur (SO4).


    IT IS ESSENTIAL THAT ANY EPSOM SALTS TO BE ADDED MUST BE ADDED TO THE HYDROPONIC SOLUTION AND BE DISSOLVED BEFORE THE ADDITION OF CALCIUM NITRATE.

    NOTE: Jack’s Hydroponic fertilizer contains NO calcium.

    After dissolving Jack’s Hydroponic and any Epsom salts in the tank, proceed as follows:

  3. Dissolve 86 ounces of Calcium Nitrate into the above 1000-gallon solution to obtain a total nutrient concentration of 150 PPM Nitrogen and 116 PPM Calcium.

    Should higher Nitrogen and Potassium levels be desired, the addition of 1-ounce Potassium Nitrate per 1000 gallons will add the following concentrations:

    Nitrogen—1.00 ppm NPotassium 2.74 ppm K

    Should higher Calcium levels be desired, the addition of 1 ounce Calcium Chloride per 1000-gallons would add the following concentrations:

    Calcium as Ca—2.09 ppm Ca

    Should higher Potash levels be desired, the addition of 1 ounce Potassium Sulfate per 1000-gallons would add the following concentrations:

    Potassium as K—3.11 ppm K

    Should higher Manganese levels be desired, the addition of 1-ounce Manganese sulfate per 1000 gallons would add the following concentrations:

    Manganese as Mn—1.87 ppm Mn

    Should higher Iron levels be desired, the addition of 1 ounce of the following per 1000 gallons will add the following concentrations:

    13% Chelated Iron as Fe EDTA — 0.975 ppm Fe
    11% Chelated Iron as Fe DTPA — 0.80 ppm Fe
    6% Chelated Iron as Fe EDDHA — 0.45 ppm Fe

    Jack’s Hydroponic Formula is heavily buffered to produce an idea working solution pH of between 6.00 and 6.50, but under unusual circumstances, it may be necessary to adjust the solution pH up or down with the use of mineral or organic acid complexes. Please consult water quality when choosing amount for pH change.
