 Athena Blended Line Grow A&B Set is a professional-grade, two-part liquid base nutrient designed exclusively for the vegetative growth phase of plants and non-flowering crops. This sediment-free formula features precisely balanced macro and micronutrients that accelerate root establishment, drive rapid structural development, and prepare crops for heavy-yielding flower cycles.
Dilution Rates & Target EC
Always use equal parts of Grow A and Grow B. Never mix the concentrates together in their pure form; dilute them into water sequentially.
  • Standard Imperial Dosage: 2 to 5 mL of Grow A and 2 to 5 mL of Grow B per gallon of water.
  • Standard Metric Dosage: 5 to 40 mL of Grow A and 5 to 40 mL of Grow B per 10 litres of water (or 0.5 to 4 mL per litre).
  • Target EC Range: Target a final Electrical Conductivity (EC) of 1.2 to 1.5 mS/cm during early to mid-vegetative growth, scaling up based on plant size, crop demand, and light intensity.
  • Target pH Range: Adjust the final solution to a pH between 5.4 and 6.0 after mixing all nutrients and additives.
Best Use Cases
  • Hydroponic Systems: Perfect for Deep Water Culture (DWC), Recirculating Hydroponic Systems (RDWC), Nutrient Film Technique (NFT), and aeroponics.
  • Inert Media: Highly effective when feeding plants grown in coco coir, rockwool, perlite, or clay pebbles.
  • Automated Dosing Systems: The completely soluble, sediment-free liquid mixes perfectly at room temperature. It will not clog fine dripper heads, emitters, or mechanical injection systems like Dosatron.
  • Soil Setups: Compatible with soil grows, though it is highly recommended to cut the standard feed dosage to lighter strengths to prevent nutrient buildup in organic media.
Strict Mixing Sequence
To prevent chemical reactions and element lockout, follow this precise sequence when preparing your reservoir:
  1. Fill your mixing tank or reservoir with clean water (Reverse Osmosis water is preferred).
  2. Add any pH stabilizers or silicon additives (e.g., Athena Balance) and mix thoroughly.
  3. Add Grow A to the water first and stir completely.
  4. Add Grow B second and stir completely.
  5. Add any supplementary additives (such as CalMag or Cleanse).
  6. Test the EC, then finish by adjusting the final pH into the target range

Frequently Asked Questions

Athena Grow A & B is a two-part liquid base nutrient designed for the vegetative growth stage. The two formulas work together to provide a balanced supply of essential mineral nutrients that support healthy roots, strong plant structure and vigorous vegetative growth.

Yes. Athena Grow A and Grow B are designed to be used together in equal amounts. Using both parts helps maintain the correct mineral ratios throughout the vegetative stage.

Shake both bottles well before use and add Grow A and Grow B separately to your water in equal amounts. Athena recommends using 2–15 ml of each part per gallon of water during vegetative growth. Always follow the appropriate Athena feeding schedule and adjust your feed strength according to your crop, growth stage and EC.

Never mix Grow A and Grow B together in their concentrated, undiluted form. Add each nutrient separately to your water and mix thoroughly to avoid unwanted reactions and maintain nutrient availability.

Yes. Athena Grow A & B is well suited to hydroponic growing and can be used with a range of irrigation and dosing systems. Its clean, sediment-free formulation helps reduce the risk of blocked irrigation lines and fine dripper heads.

Yes. Athena Grow A & B can be incorporated into nutrient programmes for plants grown in coco and other soilless growing media. Monitor EC and pH regularly and adjust nutrient strength according to your plants and growing environment.

Athena Grow A & B is designed specifically for the vegetative stage and for non-flowering plants. Use it while plants are establishing roots, foliage and structure before transitioning to the appropriate flowering nutrient programme.

Athena Grow A & B combines straightforward feeding with professional-grade mineral nutrition. The two-part system provides controlled vegetative nutrition while its clean formulation works with modern irrigation and dosing equipment, making it a strong choice for growers looking for consistent results without an unnecessarily complicated nutrient programme.
