Emerald Harvest Bloom, Micro, Grow is a professional 3-part base nutrient series designed to deliver essential plant nutrition for hydroponic gardens through growth and flowering. This base nutrients system is built as a core fertilizer foundation, giving you a complete set of primary and secondary nutrients in three coordinated parts.
Across the set, you get balanced nutrition that covers primary macronutrients nitrogen, phosphorus and potassium, along with secondary macronutrients calcium, magnesium and sulfur. For shoppers who want the hard numbers, the NPK ratings are Grow 2-1-6, Micro 5-0-1, and Bloom 0-5-4. Together, Bloom, Micro, and Grow are intended to supply the essential elements plants rely on as needs shift from growth into bloom-focused development.
A key differentiator in this series is the emphasis on chelated micronutrients for consistent, dependable mineral availability. The formula includes chelated iron, copper, manganese and zinc, alongside other micronutrients and trace elements used in modern base nutrient design. This approach is meant to help reduce the risk of deficiencies and support steady performance when crops are pushing through demanding stages.
The nutrient inputs are built from mineral sources such as potassium sulfate, monopotassium phosphate, potassium nitrate, magnesium sulfate, and nitrogen sources including ammonium nitrate and urea. Micronutrient chelates include iron EDTA, copper EDTA, manganese EDTA, and zinc EDTA, with additional trace inputs such as sodium borate and sodium molybdate listed in the formulation. These inputs reflect a high-chelation, high-precision base nutrient approach focused on thorough elemental coverage rather than a “one-note” profile.
Emerald Harvest positions this as a flexible 3-part base nutrient series suited to growers who want more control over their nutrient program across the crop life cycle. It’s also made for hydroponics and described as ideally suited for hydroponic growing mediums, making it a straightforward fit for recirculating systems and hydro-style setups that depend on clean, fully developed base nutrients. With a stated shelf life of 3 years or more under normal storage conditions, this set is a good fit for growers who want a professional foundation that stays consistent from run to run.
Step-by-step mixing and feeding instructions for Emerald Harvest Bloom - 1 Gallon.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Emerald Harvest Bloom - 1 Gallon well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.
Vegetative stage — Bloom
Flowering stage — Bloom
Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

| Available Phosphate (P2O5) | 5.0% |
|---|---|
| Water Soluble Phosphorus (P) | 2.2% |
| Soluble Potash (K2O) | 4.0% |
| Water Soluble Potassium (K) | 3.3% |
| Total Magnesium (Mg) | 0.5% |
| Water Soluble Magnesium (Mg) | 0.5% |
| Sulfur (S) | 1.0% |
Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.
Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
Sulfur is important because plants need it to build key amino acids and proteins that drive real growth, strong structure, and efficient use of nitrogen, making it uniquely different from “look-alike” nutrients that may change leaf color without supporting the plant’s core building process.
Total magnesium is important because magnesium powers chlorophyll and energy use, helping plants stay green, turn light into growth, and use other nutrients efficiently—and it’s unique because its problems often come from nutrient balance and uptake competition, not just a simple shortage.
Water soluble magnesium is important because it quickly restores the plant’s ability to make chlorophyll and produce energy, which helps stop interveinal yellowing on older leaves and improves overall nutrient use; it’s unique because it becomes available immediately in water, making it faster and more predictable than slower magnesium sources.
Water-soluble phosphorus is important because it is the fast-available form plants can absorb quickly to power energy transfer, root development, and early growth, helping plants establish faster and perform better under stress; it’s unique because it works immediately in the root-zone solution instead of relying on slow conversion before plants can use it.
Water soluble potassium is important because it helps plants quickly control water balance, move sugars to flowers and fruit, and build stronger stems during high-demand growth stages. It’s unique from many other nutrients because it acts like a regulator for plant function and stress response rather than mainly serving as a building block for plant tissues.
Magnesium sulfate supplies magnesium for chlorophyll and sugar movement plus sulfur for protein building, helping plants stay efficient and green during high-demand growth. It’s unique because it adds magnesium without extra nitrogen or calcium, so it corrects magnesium issues with fewer side effects when balance is the real goal.
Monopotassium phosphate provides fast phosphorus and potassium that support energy use, nutrient flow, and bloom development without adding nitrogen, so it helps flowering progress cleanly without pushing extra leafy growth. It’s unique because it delivers a focused PK boost in a highly soluble form, which can correct stage-related demand quickly, but it must be used carefully to avoid potassium-heavy imbalances that can block calcium and magnesium uptake.
Potassium sulfate is often preferred because it supplies potassium without added chloride and also provides sulfur, which supports protein-building and efficient nutrient use, making it a cleaner, balanced option when plants are sensitive to chloride or when you want potassium without pushing extra nitrogen or phosphorus.
