Two-part liquid veg base — 4-0-1 NPK, sediment-free, compatible with every irrigation method.
Athena Blended Grow A (4-0-1) is the nitrogen-forward Part A of Athena's two-part liquid vegetative base, formulated for licensed cannabis and hemp operations that want a clean, repeatable feed program without dry salts to weigh. Always used in equal volumes with Grow B to maintain correct mineral ratios across the full vegetative cycle.
Athena Blended Grow A is a concentrated liquid mineral nutrient carrying a 4-0-1 NPK analysis — high available nitrogen with a supporting potassium fraction. It is Part A of a two-part vegetative base; Part B (Grow B, 1-3-5) carries the complementary phosphorus, potassium, and secondary mineral load. The two parts are always dosed in equal volumes and must never be combined in undiluted form.
Grow A's nitrogen fraction is formulated to support photosynthesis, healthy respiration, and robust stalk and root development during the vegetative phase. It also carries additional nitrogen specifically to drive lush, dense foliage canopy — the structural foundation your canopy needs before transitioning to flower. The formula is fully mineral, no organic matter, no sugars, no microbial amendments.
This 55-gallon drum (SKU LQB-GWA-55G) is the commercial-scale format — engineered for operations running enough fertigation volume to make frequent small-container reorders impractical. Shelf life is two years from manufacture date when stored between 45°F and 85°F in the original sealed container.
The Blended Line's two-part liquid format is the right choice for facilities where mixing dry concentrates into stock tanks adds complexity or introduces consistency risk — multi-shift teams, new build-outs still dialing in SOPs, or operations running recirculating hydroponic systems where solution clarity matters. The formula is fully sediment-free and compatible with all dosing and irrigation hardware including fine dripper heads, making it suitable for Dosatron inline injection, drip-to-waste, recirculating DWC, hand-watering, and automated fertigation controllers.
Athena Grow A works across all commercial grow media: rockwool, coco coir, soilless/peat-based blends, and soil. It is particularly well-suited to RO water builds and inert substrate runs (rockwool, coco) where the grower controls the full mineral profile and needs a base nutrient that doesn't introduce competing chemistry. Operations already running Athena's Pro Line in flower and wanting a liquid-compatible veg program for a propagation or veg room are a natural fit.
The Blended Line uses chelated micronutrients to maintain nutrient availability across a wider pH operating range compared to non-chelated mineral programs. This matters in commercial facilities where solution pH drifts between irrigation events — chelation reduces the risk of micronutrient lock-out without requiring constant pH correction between feedings.
The formula is sediment-free by specification. Small amounts of micro-particles can appear under certain storage conditions but have no effect on mineral balance or system compatibility per Athena's published guarantee. EC-based dosing is standard protocol: monitor EC regularly and adjust dose rate within the 2–5 mL/gallon range based on crop size and stage. Adjust solution pH after mixing all fertilizers and additives — not before. Do not combine Part A and Part B in undiluted concentrate form.
The Blended Line pairs directly with Athena's supplemental range: CaMg for RO/coco calcium-magnesium top-up, Balance (potassium silicate) for pH buffering and plant structure, and Cleanse for periodic line and substrate hygiene. PK booster and Stack are available for flower-stage additive programs. HSC carries the full Athena Blended catalog.
At 55 gallons per drum, Grow A is sized to minimize reorder frequency for facilities running continuous veg rooms or large propagation benches. A 55-gallon drum at a 2–5 mL/gallon dose rate covers substantial daily irrigation volume — calculate your gallons-per-day mix volume against your target dose rate to size drum quantity and reorder cadence before your first order.
The Blended Line's two-part-per-stage architecture (Grow A+B for veg, Bloom A+B for flower) keeps the nutrient room simple: two drums per stage, equal pour, mix, pH-check, done. That repeatability is the core operational argument for the Blended Line in facilities where consistency and reduced human error matter more than absolute cost-per-gallon. For operations where cost-per-gallon is the primary driver at high volume, Athena's Pro Line dry concentrates are worth comparing — HSC carries both.

No. Grow A and Grow B are formulated as a two-part system and must always be used in equal amounts to maintain the correct mineral ratios. Using only Part A will result in an imbalanced nutrient profile. Never combine the two parts in undiluted concentrate form — always dilute each separately into your water volume.
Yes. The Blended Line's sediment-free liquid formula is compatible with all dosing and irrigation systems, including fine dripper heads, Dosatron inline injectors, drip-to-waste systems, recirculating hydroponic systems, and hand-watering. No dry salts means no dissolution step and no risk of undissolved material clogging emitters.
The Blended Line is a ready-to-dose liquid — no weighing, no dissolution into stock tanks. It's well-suited for recirculating systems, multi-shift operations where simplicity reduces error, and facilities where liquid handling is preferred. The Pro Line uses dry concentrates designed for large-volume stock tank mixing, and typically offers a lower cost-per-gallon at very high fertigation volumes. HSC carries both; contact us to compare program costs for your specific daily mix volume.
Athena's published feed schedules provide week-by-week EC targets. Common practice is ramping from approximately EC 0.6 at seedling/early clone stage up to EC 1.4–1.6 by late veg, adjusting dose rate within the 2–5 mL/gallon range. Monitor EC at the reservoir and at run-off, and adjust based on your specific crop, environment, and water baseline. Athena's Blended Feed Schedule (standard and metric versions) is available as a free download from Athena's website.
Athena Blended Grow A is available in 1-gallon, 5-gallon, and 55-gallon formats through HSC. The 55-gallon drum (LQB-GWA-55G) is the primary commercial SKU. Request a quote for single-drum or multi-drum orders, and ask about pairing with Grow B and the rest of the Blended Line to consolidate freight.
