Emerald Harvest Grow, 55 gal

Nitrogen-Dominant Component of the Grow, Micro, Bloom System, 55 Gal

Emerald Harvest Grow is the vegetative-phase component of the Grow, Micro, Bloom professional 3-part base nutrient series. In the 3-part system, Grow provides the nitrogen-forward macronutrient ratio suited to the phase when a plant is building leaf area, root mass, and structural tissue, while Micro anchors the micronutrient profile and Bloom carries the phosphorus- and potassium-forward flowering ratio. Beyond its nitrogen emphasis, Grow supplies the full essential-element set: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, plus chelated iron, copper, manganese, and zinc. During vegetative growth, Grow is used at a higher ratio relative to Bloom; as the plant transitions to flowering, that ratio shifts the other way.

The 55-gallon size is built for commercial operations running Grow across a large canopy on a recurring feeding schedule.

Key Features & Benefits

• Nitrogen-dominant veg formula — macronutrient ratio weighted for vegetative growth, root development, and structural establishment.
• Full-spectrum macronutrient bottle — nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, all in one concentrate.
• Chelated trace elements — iron, copper, manganese, and zinc stay plant-available across a wider pH range.
• Independent mixing ratio — adjust Grow relative to Bloom and Micro at each stage instead of using one fixed blend.
• Built for the 3-part system — designed to be mixed with Emerald Harvest Micro and Bloom, not used alone.

Who Should Use Grow

Grow fits growers who want to fine-tune their feeding ratio through vegetative development before shifting toward Bloom for flowering. It's built for any high-yield crop in soil, coco, or hydroponic media.

About Emerald Harvest Grow

Grow has anchored the vegetative side of Emerald Harvest's three-part Grow, Micro, Bloom system since the Santa Rosa, California brand introduced that line as its original product family in 2015.

Frequently Asked Questions

What role does Grow play in the 3-part system?

Grow supplies the nitrogen-forward macronutrient ratio used during vegetative growth, mixed alongside Micro and Bloom. As plants transition toward flowering, the Grow ratio is lowered while Bloom is raised.

How do I mix the three components together?

Mix in Micro first, then Grow, then Bloom, stirring the reservoir thoroughly after each addition. Adding them in that sequence keeps the concentrated mineral salts from reacting with each other before they're diluted.

What micronutrients does Grow include?

It provides chelated iron, copper, manganese, and zinc alongside calcium, magnesium, and sulfur. The chelated form keeps those trace elements plant-available across a broader pH range than unchelated mineral salts.

Can Grow be used on its own without Micro and Bloom?

No, Grow is one component of the 3-part system and isn't a complete standalone nutrient by itself. It's intended to be mixed with Micro and Bloom for the full macro- and micronutrient profile.

When should I start reducing the Grow ratio in my feeding schedule?

Start reducing Grow relative to Bloom once the plant begins its transition into flowering, typically as flower sites start forming. Micro is kept at a consistent ratio through both the vegetative and flowering phases.
