  • Athena Balance

    Athena Balance

    Athena Balance is a simple formula specifically concentrated to buffer irrigation water and stabilize to ideal pH. Commercial growers find better results, particularly with reverse osmosis (RO) water, when buffering first with Athena Balance. Pure RO water has an unstable chemical structure that can trap other nutrients when added without a buffer. Athena Balance adds just enough to the water to create a more homogenous fertilizer solution and reduce the need to pH-adjust after mixing.  Formula is sediment-free and is compatible with mechanical dosing systems (Dosatron). Athena Balance is not recommended for electronic dosing systems (Netafim).

  • Athena Bloom

    Athena Bloom

    Athena Bloom is a simple and clean 2-part formula designed for the flowering stage of growth for flower- and fruit-producing plants. We blend top of the line macronutrients and chelated micronutrients to achieve greater nutrient uptake ability across a wider pH range in any combination of grow method, water type, and media. This 2-part blended liquid formula should be used in equal amounts during the flowering phase. Our carefully formulated mineral ratios provide essential nutrients which support bud and flower development. Formulas are sediment-free and are compatible with all dosing and irrigation systems 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 RatesAdd 2-15 mL of Athena Bloom A per gallon of water during the flowering 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 Bloom A & Bloom B to maintain proper mineral ratios.

  • Athena Bloom Bag

    Athena Bloom Bag

    Flowering plants require higher amounts of phosphorus (P) and potassium (K) to increase flower bulk and support high metabolic activities. Athena Pro Bloom contributes ideal levels of macro- and micro-elements, including sulfur (S), used for increasing potency and flavors.  Balanced NPK and essential microelements (when used with Pro Core) 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: Get a measuring container that has accurate gallon marks on it. Fill half of the stock tank with water. Slowly pour granules into water while agitating, then mix thoroughly to solubilize. Add additional water until it gets exactly to the 12.5 gallon mark. Vigorously mix until all granules are solubilized. Mix your BATCH RESERVOIR:Using the recommended 2 lbs per gallon chart, determine the mL per gallon to achieve your desired EC. IngredientsPotassium Phosphate, Potassium Sulfate, Magnesium Sulfate, Iron DTPA

  • Athena CaMg

    Athena CaMg

    Athena CaMg is designed to supplement either of our 2-part liquid formulas. Some cultivars and growing conditions may require higher doses of calcium, magnesium, iron and nitrogen during heavy growth and development phases. This product effectively corrects these common deficiencies without throwing off overall elemental balance. In systems using reverse osmosis (RO) water and plants grown in inert media, such as coco and rockwool, Athena CaMg is particularly useful. Although our 2-part formulas already provide sufficient levels of calcium and magnesium, some growers find supplementation helpful in demanding conditions. Application RatesAdd 2-10 mL of Athena CaMg per gallon of water during all stages as needed. See Feed Schedules for specific application recommendations. Best Practices Shake well before use. Use clean measuring instruments – do not put anything into the bottle. Some applications may require different dosages. Recommended for hydroponic use, especially with inert media and when using reverse osmosis (RO) water. Monitor EC regularly and adjust accordingly based on crop and growth stage. Adjust pH to proper levels after mixing all fertilizers and additives. Store closed in original packaging at a temperature between 45°F and 85°F. BEST PRACTICES Shake well before use.

  • Athena Cleanse

    Athena Cleanse

    Athena Cleanse is made from Hypochlorous acid. This mild acid is derived from salt and a proprietary electrochemical treatment process. The result is a unique, plant-safe chemical with powerful oxidative properties to prevent mineral buildup, increase Oxidation-Reduction Potential (ORP), and descale irrigation systems.  Key Features Non-toxic and non-nutritive – safe to use on plants in any stage of growth Works to descale irrigation systems and decompose residual organic matter Effective as a final flush to remove mineral buildup (scale) in growing media and irrigation lines Very low TDS – does not throw off mineral balance Keeps irrigation system cleaner and running efficiently for longer How To Use  System Maintenance: Irrigation systems that are regularly maintained with Athena Cleanse treatment will last longer, and run more optimally throughout. This is because Athena Cleanse helps break down scale, mineral buildup, and other inanimate organic matter that has been lodged in the system.  Regular Use: Use a dilute mixture of 2-5 mL of Athena Cleanse per gallon of water for regular maintenance.  Severe Conditions: Increase rate to 5-10 mL per gallon of water for combating severe reservoir and growing media conditions.  RDWC and Other Recirculating Hydroponics Systems: Any recirculating or deep water culture (DWC) irrigation system should use Athena Cleanse to remove mineral residue and reduce scale.  Using Athena Cleanse in a recirculating or DWC system helps break down materials with lower solubility ratings, such as mineral complexes that are no longer available to plants. Mineral buildup and lockout is a major cause of deficiencies and plant health problems – solve these issues with Athena Cleanse.  Media/System Flush Mix: Use Athena Cleanse at a rate of 5-10 mL per gallon of water during the final flush stage to help reduce residual mineral buildup in the growing media.  This procedure may be used at any time during vegetative or flowering phases if the growing media or irrigation system develops mineral imbalance or unwanted buildup.  Foliar Applications: Mix 375 mL of Athena Cleanse per gallon of water and spray evenly. Test on a small area first to ensure no damage. SurfaceCleaning:  Spraying cultivation surfaces, work areas and irrigation equipment with a dilute solution of Athena Cleanse (375 mL per gallon) helps maintain a clean environment without toxic and dangerous chemicals. Maintain operational excellence and extend equipment life, such as irrigation system filters, by running treated water through the system regularly.

  • Athena Fade 3.79L

    Athena Fade 3.79L

    Athena Fade is a nitrogen-free finishing flush that provides your plants with the immobile nutrients they need (calcium and microelements), to ensure they don’t starve during the critical ripening stage. Excess nitrogen is known to delay flower maturation. It’s important to taper or even remove nitrogen at the end of the flowering cycle to support crop maturation and ensure flowers reach their genetic potential. After extensive testing, we’ve found that running Athena Fade with Athena Pro Bloom during the last 3 weeks of flower increased total cannabinoid and terpene production without increasing the risk of deficiencies and bud rot. Nitrogen-free finishing enhancer Contains optimal levels of calcium and microelements for finish Same liquid dilution rate as Athena Pro Core (at 2 lbs per gallon concentrate) Replace Athena Pro Core during the final 3 weeks of flower Application RatesAdd 10-19 mL of Athena Fade per gallon of water during the final 2-3 weeks of the flowering phase.
