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.

Ammoniacal Nitrogen (N) is a plant-available form of ammonium (NH₄⁺) that provides a steady, gentle source of nitrogen for healthy green growth. Unlike fast-release nitrogen types, ammoniacal nitrogen feeds plants slowly, helps stabilize root-zone pH, and works well in cooler temperatures. It is commonly used during early vegetative growth because it supports strong leaf development without burning young roots. If plants show pale leaves, slow growth, or weak stems, they may need more available ammoniacal nitrogen.
Ammonium nitrate is unique because it provides nitrogen in two plant-usable forms at once, which can give a fast green-up while still supporting steadier uptake depending on the root-zone conditions. That matters because it can correct true nitrogen shortages quickly, but it also needs careful balance since too much can push overly soft growth and trigger pH drift and nutrient imbalances.
Boron is essential because it stabilizes cell walls, supports root and shoot growth, and regulates sugar movement throughout the plant. What makes boron unique is its limited mobility and extremely narrow range between deficiency and excess, which causes new growth to show symptoms rapidly when levels fall out of balance.
Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.
Calcium nitrate is important because it supplies calcium in a fast, highly available form that supports strong new growth and healthy root tips, while also providing nitrate nitrogen for steady, usable growth energy. It’s unique because it delivers calcium together with nitrate nitrogen, making it especially effective during rapid growth phases when plants need both structure-building calcium and immediately available nitrogen at the same time.
Chelated copper is important because it supports key enzyme systems that drive energy flow, strong tissue formation, and healthy new growth, while chelation keeps copper available and stable in the root zone. It’s unique because plants need it in extremely small amounts and it can become unavailable or toxic more easily than many other micronutrients, so chelated forms help deliver precise, predictable copper without big swings.
Chelated iron is important because it keeps iron usable for plants even when growing conditions would normally lock iron out, helping prevent the classic yellow-new-leaf symptom caused by low chlorophyll production. It is unique from other iron sources because the chelation protects iron from becoming insoluble, making it a more reliable way to correct iron-related chlorosis when regular iron can fail.
Chelated manganese is important because it keeps manganese available for photosynthesis and enzyme activity even when pH or water chemistry would normally lock it out, and it’s unique from similar micronutrients because it strongly supports the plant’s energy-processing systems that drive healthy, resilient new growth.
Chelated zinc is important because it keeps zinc available for uptake even when pH or root-zone conditions would normally lock zinc out, helping plants form normal-sized, healthy new growth—something that makes zinc uniquely different from many other nutrients that mainly affect older leaves or simple leaf color changes.
Copper EDTA helps keep copper dissolved and available to roots longer, so plants can absorb it more consistently when copper would otherwise tie up in the growing medium. It’s important because copper supports enzyme activity and healthy new growth, and it’s unique because the chelate improves predictability while allowing very small, controlled copper dosing.
Molybdenum is important because it helps plants convert nitrogen into usable building blocks for chlorophyll and growth, and it’s unique from many nutrients because it mainly supports enzyme-driven “nutrient use” rather than directly building plant tissue.
Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.
Sodium is important to manage because it can quietly build up in the root zone, making it harder for plants to absorb water and essential nutrients like potassium, which leads to slow growth and leaf burn. It’s unique from most nutrients because the problem is usually excess and imbalance—not a shortage—so fixing it often means preventing buildup and restoring root-zone balance rather than adding more feed.
Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.
Urea nitrogen is important because it can supply a high-impact source of nitrogen that supports chlorophyll production and fast leafy growth, but it’s unique from other nitrogen forms because it usually must convert in the growing environment before roots can use it consistently, making correct application and conditions critical for avoiding loss, burn, or sudden imbalance.
Iron EDTA keeps iron dissolved and available long enough for roots to absorb it, which is why it can quickly improve new growth color when iron is tied up in the root zone. It’s unique because the EDTA chelate balances stability and accessibility, making iron more reliably usable in mildly acidic to near-neutral conditions compared to many non-chelated iron forms.
Manganese EDTA is unique because the EDTA chelate keeps manganese stable and more available during delivery, helping plants absorb it more reliably when manganese would otherwise lock up. This matters because manganese drives key enzyme functions tied to photosynthesis and healthy new growth, so consistent availability can prevent pale, chlorotic young leaves and stalled vigor.
Potassium nitrate is often better for quick correction when the plant needs both potassium and fast nitrate nitrogen, because it dissolves cleanly and is taken up quickly, unlike potassium sources that don’t supply nitrogen. It’s unique because it can restore leaf color and growth momentum while also improving water regulation, but it can backfire if nitrogen is already high or if salt levels are already stressing the roots.
Sodium borate mainly supplies boron, a micronutrient plants need in tiny amounts to build healthy new growth and develop flowers and fruit normally, but it’s unique because the safe range is narrow and too much can quickly cause tip damage and leaf burn.
Sodium molybdate supplies molybdenum, a trace micronutrient that helps plants convert nitrate nitrogen into usable building material, so growth and green color stay steady; it’s unique because it works as a tiny-dose “nitrogen unlocker” rather than a bulk nutrient.
Urea can burn plants because it must convert in the root zone, and that conversion can create a concentrated, temporarily harsh micro-zone that stresses roots, especially if urea is piled, left on the surface, or not watered in. That conversion step is what makes urea unique compared with nitrogen forms that are already plant-available, so correct placement and moisture are critical.
Zinc EDTA is important because it keeps zinc available in the root zone when pH or water chemistry would normally tie zinc up, helping new growth develop normally before deficiency symptoms get worse. It’s unique from other zinc forms because the EDTA chelate shields zinc in solution, making delivery more consistent when conditions are not ideal.
