Emerald Harvest Grow, 270 gal

Emerald Harvest Grow – Grow/Micro/Bloom 3-Part Base Nutrient, 270 Gallon

Emerald Harvest Grow is the nitrogen-dominant vegetative component of the Grow/Micro/Bloom professional 3-part base nutrient series. In the 3-part system, Grow provides the nitrogen-forward macronutrient ratios suited for the vegetative growth phase — when the plant is building leaf area, root mass, and structural tissue. Micro provides the micronutrient foundation used consistently across all growth stages. Bloom provides the phosphorus- and potassium-dominant ratios for the flowering phase. The three components are kept separate so growers can adjust mixing ratios at each stage of the grow cycle, giving experienced growers maximum flexibility to match the plant's specific nutritional demand at each phase.

In addition to its nitrogen-forward macronutrient ratio, Grow provides the full essential element profile: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S), plus chelated trace elements including iron, copper, manganese, and zinc. Chelated micronutrients remain plant-available across a broader pH range than non-chelated mineral salts. During vegetative growth, Grow is used at a higher ratio relative to Bloom. As the plant transitions to flowering, the Bloom ratio is increased while Grow is decreased. Micro is used at a consistent ratio across both phases.

Who Should Use Grow

Grow is for experienced growers running the Grow/Micro/Bloom 3-part system who want the ability to fine-tune their feeding ratios independently at each growth stage. It is suited for any growing medium and any high-yield indoor crop.

Mixing Order for the Grow/Micro/Bloom 3-Part System

When mixing a 3-part nutrient solution, always add nutrients to the reservoir water — never add water to the concentrated nutrients and never mix concentrates together directly. Add Micro first and mix thoroughly, then add Grow and mix again, then add Bloom and mix again before checking pH and EC. This mixing order — Micro first, then Grow, then Bloom — prevents precipitation reactions between the concentrated component formulas. During vegetative growth, use a higher ratio of Grow relative to Bloom. As the plant enters the reproductive phase, progressively reduce Grow and increase Bloom. Follow Emerald Harvest's recommended feeding schedule as a starting point.

Frequently Asked Questions

What is Grow's role in the 3-part system?

Grow provides the nitrogen-dominant macronutrient ratios for the vegetative phase. It is used alongside Micro and Bloom, with the ratio of Grow-to-Bloom adjusted based on the plant's growth stage.

In what order should I add the 3 components?

Add Micro first, then Grow, then Bloom. Always add to reservoir water — never mix concentrates together directly.

Do I use Grow during flowering?

Yes, but at a reduced ratio. As the plant transitions to flowering, the Grow ratio is decreased while Bloom is increased. Grow is still part of the mix throughout most of the grow cycle.

What chelated micronutrients does Grow provide?

Grow provides chelated iron, copper, manganese, and zinc, along with calcium, magnesium, and sulfur as secondary macronutrients.

Is Grow a standalone nutrient or does it need Micro and Bloom?

Grow is one component of a 3-part system and is intended for use with Emerald Harvest Micro and Bloom for a complete nutrient program.
