    Lightbulb Growing Tomatoes with Jackís

    Things are really moving now in the garden with the onset of the warmer temperatures. Your transplants should be responding to their new environment and producing new growth. The root systems are ready to take up all the nutrients they need to maximize their bud set and flower initiation.

    Here is the feeding program I use for my tomato plants and some of the reasons I use it.
    • After transplanting the tomatoes I want to get them off to a great start. In order to do that you need to provide plenty of phosphorus to the root system which has not yet spread out in the soil. I use the Jack’s Classicģ Blossom Booster 10-30-20 at 1 tablespoon per gallon when I set the plants in place.

    • After the first week I come back and make my first application of Jack’s Classicģ 20-20-20. This 1-1-1 ratio fertilizer is just what the plant needs to grow in mass with plenty of new leaves and thick stems that will be the factories to produce lots of energy that will give you a high fruit yield. I repeat these feedings every 10 days to make certain there are no nutrient stresses to hold back production.

    • Tomatoes respond well to increased levels of magnesium in the feed program. Be sure to add some additional Epsom salts (1 teaspoon per gallon) to your fertilizer applications. Your leaves will develop a deep green in response to the fertilizer applications and the increased magnesium.

    • After the first month I switch my feeding program to a combination of 1 tablespoon of 20-20-20 and 1 tablespoon of 10-30-20 in 2 gallons. That combination makes a 15-25-20 fertilizer, which is a great formulation to feed as the plants are setting buds and fruit. Stick with this combination until all your fruit is set and the first of the fruit is starting to turn red

    • From this point on I stick with the Blossom Booster 10-30-20. The high potassium will let the fruit finish nicely. Apply the fertilizers every 10 days or so right through the end of the crop.




    Jack's Hydroponics


    Here at JR PETERS, we are excited to offer nutrients to the hydroponic industry with this truly innovative line of fertilizers. One that is scientifically based and proven high quality to ensure absolute nutrient solubility and availability to the plants.

    Choosing the right formula based on your growing environment

    Although all of our Jack’s Classic and Jack’s Professional formulas are completely water soluble, which allow all of the nutrients to be available to your plants in a hydroponic solution, many formulas are not ideal for a true hydroponic growing system. The first step in choosing the ideal formula is to understand more about your growing environment.

    GROWING IN A SOIL (or SOILLESS) ENVIRONMENT vs. HYDROPONIC:
    Although our Jack’s Classic 20-20-20 is completely water soluble - which allows all of the
    nutrients to be available to your plants in a hydroponic solution - it is not ideal for a true
    hydroponic growing system. This is due to the specific blend of nitrogen forms that make up our
    20-20-20 formulation (as well as most retail fertilizers).
    Jack’s 20-20-20 is best suited for roots grown in soil or soilless mix. In a soil environment, the
    nitrogen forms in 20-20-20 can be easily taken up and converted to the nitrogen forms that the
    plants use best. In a true hydroponic system ( water flowing environment), these nitrogen
    conversions will not occur easily, and some forms of nitrogen, (like urea and ammonium) can sit
    in the root zone a bit too long when certain low light or low temperature conditions arise. When
    this happens, these stagnant forms of nitrogen act as a great source of food for other things like
    algae, bacteria and microorganisms, causing a build-up of these materials in your hydroponic
    environment. This creates a real mess and greatly reduces the effectiveness of the nutrients in
    solution.
    Our best seller and most well known formula for home and hobbyist growers, Jack’s 20-20-20, is best suited for roots grown in soil or soilless mix. In a soil environment, the nitrogen forms in 20-20-20 can be easily taken up and converted to the nitrogen forms that the plants use best. In a true hydroponic system (water flowing environment), these nitrogen conversions do not occur easily; some forms of nitrogen (like urea and ammonium) can sit in the root zone a bit too long when certain low light or low temperature conditions arise.

    When this happens, these slow to change forms of nitrogen act as a great source of food for other things like algae, bacteria, and microorganisms causing a build-up of these materials in your hydroponic environment. This creates a real mess and greatly reduces the effectiveness of the nutrients in solution.

    For a true hydroponic system, it is NOT advised to grow with a typical 20-20-20; however, this formula is very well suited for any indoor or outdoor system that uses a soilless or soil containing media.



    GROWING IN A TRUE HYDROPONIC SET UP


    Our researchers at J.R. Peters have a formulated a 2-step fertilization system specifically for
    hydroponic applications, that will supply the ideal nutrient levels to your plants. These fertilizer
    products are available in our commercial line called Jack’s Professional. Using a combination of
    Jack’s Professional Hydroponic 5-12-26 and Jack’s Professional Calcium Nitrate 15.5-0-0, this
    system can be easily customized to fit your operation, whether you grow 2 or 20,000 hydroponic
    plants.





    TRADITIONAL HYDROPONIC FORMULAS

    A traditional hydroponic two-part fertility system uses a combination of Jack’s Professional Hydroponic 5-12-26 and Jack’s Professional Calcium Nitrate 15-0-0, this system can be easily customized to fit your operation, whether you grow 2 or 20,000 hydroponic plants. For a traditional system, follow the special mixing directions below.

    SPECIAL MIXING DIRECTIONS FOR TRADITIONAL NUTRIENTS

    Jack’s Hydroponic formulation and Jack’s Calcium Nitrate are packaged separately, and require a little special attention when mixing - in order to avoid forming a precipitant in the tank. These products must be dissolved either in a two-tank system or in dilute (or Ready-to-Use) quantities. Following these specific stepwise directions is vital, along with the knowledge that these items should NEVER be mixed in a concentrate tank together.



    On a small scale, the easiest way to use our Jack’s Hydroponic System is to create a ready-to-use solution by combining Ĺ teaspoon of each formulation per gallon of water-just make sure you do not combine them in any stronger concentrations or the materials will solidify and drop to the bottom of the solution. Also, be sure to aerate the solution with a bubbler or change the solution every other day to maintain proper oxygen levels.


    Note: An alternative to mixing the products together is to apply them separately, using one at a time and alternating them every other feeding. This will assure that your plants are receiving the ideal levels of nutrients.



    NEW – COMPLETE, ONE BAG FORMULAS

    The research and development team at JR PETERS has developed several new products that deliver all the essential elements for hydroponically grown crops with the ease and innovation of a one bag blend. These high quality and extremely soluble nutrient blends deliver the optimum balance of macro, secondary and micronutrients that can be mixed together in ready to use or concentrated form.

    The strength of the fertilizer solution should be determined by the amount of Nitrogen in the formula. Directions for each blend can be found on the bag, and should always be referenced with specific nutrient targets for the crops you are growing.

    These specialized hydroponic products are available directly through the website. Products are available in 1lb, 5lb and 25lb containers. Feel free to place your order directly online or call the lab directly to order.
