  • Athena Pro Core provides strong baseline nutrition across all stages of plant growth. Nitrogen to assemble chlorophyll and amino acids. Calcium to build structure. Essential microelements to catalyze photosynthesis, enzyme production and a multitude of important plant processes.

     

    • Readily available Nitrogen, Calcium, and essential microelements
    • Fully soluble dry fertilizer, no particulates or sediment
    • Works with any dosing system: Dosatron, Netaflex, Rhythm
    • Mixes completely at room temperature
    • Low heavy metal content

    Ideal for mixing stock tanks and compatible with all dosing systems. This large-grind mix is 100% soluble and will not clog irrigation systems or leave sediment in reservoirs.


    We discourage mixing Pro Line in small amounts directly into the reservoir.  We would rather turn the Pro line into a concentrated liquid first  and then use that liquid to mix your batch tanks.


    Nutrient Preparation Steps for a STOCK CONCENTRATE:

    1. Get a measuring container that has accurate gallon marks on it.
    2. Fill half of the stock tank with water.
    3. Slowly pour granules into water while agitating, then mix thoroughly to solubilize.
    4. Add additional water until it gets exactly to the 12.5 gallon mark.
    5. Vigorously mix until all granules are solubilized.  

    Mix your BATCH RESERVOIR:

    Using the recommended 2 lb per gallon chart determine the ml per gallon to achieve your desired EC.

  • Athena Grow is a simple and clean formula designed for the vegetative stage of growth and for non-flowering plants. Our careful balanced mineral ratios help facilitate optimal plant development including photosynthesis, healthy respiration, and robust stalk and root growth.


    This 2-part blended liquid formula should be used in equal amounts during the veg phase to stimulate the rapid onset of bud production, increase flowering sites, and promote high-quality yields.


    Formulas are sediment free and are compatible with all dosing and irrigation systems in including fine dripper heads. Small amounts of micro-particles are occasionally visible in some conditions but will not affect mineral balance or system compatibility.


    Application Rates

    Add 2-5 mL of Grow A per gallon of water during the vegetative growth phase.


    See Feed Schedules for specific application recommendations.


    Best Practices

    Shake well before use.

    • Use clean measuring instruments--do not put anything into the bottle.
    • Always use equal parts of Athena Grow A & B to maintain proper mineral ratios.
    • Monitor EC regularly and adjust accordingly based on crop and growth stage.
    • Adjust to pH to proper levels after mixing all fertilizers and additives.
    • Do not combine in undiluted form.
    • Store closed in original packaging at a temperature between 45° F and 85° F.

  • Athena PK is a balanced bloom boosting complement to our Bloom fertilizers. This clean liquid booster is designed to supplement during the mid- to late-flowering phase. Athena PK is a low Nitrogen booster that provides additional Phosphorus and Potassium that high-yielding plants require for maximal production. Many PK boosters add far too much of these elements and create a cascade of problems, such as reducing Calcium and Magnesium availability. Balanced elemental bioavailability is essential in the flowering phase to boost essential oil and terpene production.


    Application Rates:

    Add 3-10 mL per gallon of water during the flowering phase starting in week 3.


    See Feed Schedules for specific application recommendations.
