Athena Blended Grow B

What Athena Blended Grow B Is

Athena Blended Grow B is the B-part of the two-bottle vegetative base nutrient in Athena's Blended Line. The Blended Line is a fully liquid system — no dry salts to weigh or dissolve — designed to keep feeding simple and repeatable across every veg cycle. Grow B handles phosphorus, potassium, magnesium, and sulfur delivery during the vegetative phase, while Grow A carries the nitrogen, calcium, and chelated micronutrient load. The two parts are always mixed in equal volumes; splitting the chemistry across A and B prevents precipitation and keeps the solution stable in reservoir conditions.

The formulation is sediment-free and fully soluble in all water conditions. Unlike blended liquids that leave residue in lines or reservoirs, Grow B is engineered to stay clean from stock tank through emitter — including fine dripper heads. It is compatible with recirculating systems, drain-to-waste drip, hand-watering, and automated Dosatron or inline injection setups.

Who It's Built For

Athena Blended Grow B is positioned for licensed cannabis and hemp operators who want a proven, commercially tested nutrient program without the overhead of a dry-concentrate mixing protocol. It fits mid-scale and multi-room facilities where staff consistency matters — every person filling a reservoir gets the same result because the dosing is liquid, measured in mL, and backed by a published week-by-week feed schedule.

It also works for craft operators running coco, rockwool, or recirculating hydroponic setups who want EC-driven precision without a long additive stack. The Blended Line's philosophy is minimal inputs, clean chemistry, and predictable plant response — Grow B is the cornerstone of that during the vegetative stage. Operators on any grow medium (soil, coco, rockwool, DWC) can run it; it is not substrate-specific.

Key Features

NPK 1-3-5 with 0.89% magnesium and 1.3% sulfur. The elevated phosphate and potassium in Grow B balance Grow A's high nitrogen and calcium contribution, producing a complete veg mineral profile when combined. Magnesium sulfate in the formulation supplies Mg for chlorophyll production and S for amino acid synthesis — both high-demand in the vegetative phase — without adding extra nitrogen or calcium that could skew the overall ratio.

Dosing is adjustable from 2 to 5 mL per gallon, allowing operators to ramp from seedling-strength to full vegetative feed without switching products. Always used in equal parts with Grow A to maintain proper mineral ratios. EC monitoring is recommended throughout; Athena's published Blended Line feed schedule provides week-by-week EC targets from propagation through late veg.

The formula is derived from Monopotassium Phosphate, Potassium Nitrate, Copper EDTA, Magnesium Sulfate, and Monoammonium Phosphate — a straightforward mineral-salt source list with no added surfactants, sugars, or biologicals that could foul irrigation equipment or complicate residue testing.

How Grow B Fits the Blended Program

Grow B is used exclusively during the vegetative stage alongside Grow A. At the transition to flower, both Grow A and Grow B are replaced entirely by Bloom A and Bloom B — running Grow A/B past the flip over-delivers nitrogen at a point when the plant's demand is shifting toward phosphorus and potassium for bud development. Athena's published schedule makes the transition point explicit.

Supporting products in the Blended Line that run alongside Grow B include CaMg (calcium, magnesium, and iron supplement — especially relevant in RO water and inert substrates like rockwool or coco), Athena Balance (potassium silicate-based pH stabilizer), and Cleanse (system maintenance and pre-harvest line clearing). None of these additives are required to run the base program, but they are designed to integrate without compatibility issues. Grow B is available from Hydro Supply Co. as a standalone gallon (LQ-GWB-1G) or as part of bundled Blended Line configurations.
