Emerald Harvest Micro, 1 gal

Emerald Harvest Micro – Complete Micronutrient Solution for the 3-Part Series

Emerald Harvest Micro is one of three components in the professional Grow, Micro, Bloom base nutrient series. It supplies nitrogen, phosphorus, potassium, and a comprehensive profile of chelated micronutrients — including iron, copper, manganese, and zinc — that support enzymatic and metabolic processes throughout the plant's entire life cycle.

Unlike simpler 1- or 2-part systems, the 3-part format allows cultivators to adjust the ratio of each component independently. Micro anchors the program by delivering the micronutrient foundation that both Grow and Bloom build upon, making it an essential part of a tailored professional feeding program across any growing medium.

Key Features & Benefits

• Nitrogen, Phosphorus & Potassium — Provides primary macronutrients in a formulation designed to work alongside Grow and Bloom for a complete nutritional spectrum.
• Chelated Iron — Chelated iron remains plant-available across a range of pH levels, reducing the risk of micronutrient lockout in hydroponic and soil systems.
• Copper, Manganese & Zinc — Delivers essential trace elements that support enzyme function, chlorophyll synthesis, and overall metabolic activity.
• Calcium & Magnesium — Supplies secondary macronutrients important for cell wall integrity and efficient photosynthesis.
• Flexible Mixing Ratios — Part of a 3-part system that lets experienced growers fine-tune macro and micronutrient levels to match their plants' exact needs at each stage.
• Professional Series Compatibility — Used in combination with Emerald Harvest Grow and Bloom to deliver a complete, stage-specific nutrient program from propagation through harvest.
• Multiple Volume Options — Available in qt, 1 gal, 2.5 gal, 6 gal, 15 gal, 55 gal, and 270 gal formats to suit operations of any scale.

Who Should Use Emerald Harvest Micro?

Emerald Harvest Micro is suited for experienced growers, commercial operations, and cultivators who want precise control over their plants' macro and micronutrient intake. The 3-part format requires more dialing in than single-bottle solutions, making it a strong fit for those who track EC, pH, and feeding schedules closely and want the ability to adjust each component independently.

How Micro Fits Into the Grow, Micro, Bloom Program

In the Grow, Micro, Bloom 3-part system, Micro is used throughout the entire growth cycle — from early vegetative growth through late flowering. The ratio of Micro relative to Grow and Bloom shifts depending on the stage: higher Grow ratios support early vegetative development, while increased Bloom ratios favor flowering. Micro remains present in every feeding. Always add nutrients to your reservoir in order — Micro first, then Grow, then Bloom — and adjust pH after mixing. Refer to Emerald Harvest's published feed chart for stage-specific ratios and dilution rates.

Frequently Asked Questions

What nutrients does Emerald Harvest Micro supply?

Micro delivers nitrogen, phosphorus, potassium, calcium, magnesium, and chelated micronutrients including iron, copper, manganese, and zinc.

Can Emerald Harvest Micro be used as a standalone nutrient?

No. Micro is one component of the 3-part Grow, Micro, Bloom system and does not provide a complete nutrient profile on its own.

What order should I add Grow, Micro, Bloom to my reservoir?

Add Micro to the reservoir first, then Grow, then Bloom. Never mix the concentrated components together before diluting them in water.

Is Emerald Harvest Micro compatible with coco coir and soil?

Yes. The Grow, Micro, Bloom series works in hydroponic systems, coco coir, and soil media. Adjust dilution rates based on your growing medium and source water quality.

What sizes is Emerald Harvest Micro available in?

Micro is available in 1 qt, 1 gal, 2.5 gal, 6 gal, 15 gal, 55 gal, and 270 gal.
