General Hydroponics Diamond Nectar is a plant food and humic acid supplement for growers who want better nutrient uptake from vegetative to flowering. This plant nutrition supplement centers on premium grade humic acids to support efficient nutrient movement in the root zone, especially when consistent performance matters across changing stages.
Diamond Nectar focuses on the chelating action of humic acids to help keep nutrients more available at the point of uptake. General Hydroponics describes how it accelerates nutrient absorption where mineral foods enter the plant, helping valuable elements move in a more usable form. In nutrient rich hydroponic environments, it targets immobile and molecularly heavy compounds that can otherwise be slower to move. Those compounds are transported through and into plant tissues, supporting faster growth and greater yields when plant demand climbs.
A compact facts layer: Diamond Nectar is listed as 0-1-1 NPK, which keeps the formula focused on its humic-acid role while supplying a small amount of phosphorus and potassium. The stated nutrient sources are phosphoric acid and potassium hydroxide. Together with its premium grade humic acids, this combination positions Diamond Nectar as a straightforward plant food for growers who want nutrient delivery to stay responsive without changing their overall program direction.
Diamond Nectar is suited for all types of growing media and for a wide range of crops. General Hydroponics lists vegetables, herbs, fruits, flowers, and other high value crops as plant categories it supports. For media, it fits water culture, rockwool, coco, potting mix, peat lite mix, and in-ground soil. That broad flexibility makes it easy to keep the same humic-acid approach whether you run recirculating systems, hand-water containers, or maintain garden beds.
This is a good fit for growers who want premium grade humic acids to support nutrient absorption and nutrient transport from vegetative to flowering, including setups that rely on water culture or mixed media gardens.
Step-by-step mixing and feeding instructions for General Hydroponics Diamond Nectar - 1 Quart.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of General Hydroponics Diamond Nectar - 1 Quart 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 — Diamond Nectar
Flowering stage — Diamond Nectar
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.
Storage and handling
Store this product in its original closed container, in a cool, dry and well-ventilated area. Protect from extreme temperatures and direct sunlight. Keep container tightly sealed when not in use.
Avoid release to drains, natural waterways or outdoor soil. Dispose of unused product and empty containers in accordance with local regulations and the directions on the label.
Important: If medical advice is needed, keep the product label or container available. Always follow the specific instructions and safety recommendations provided by the manufacturer. This safety notice is intended as general guidance and does not replace official label directions or documentation.
| Available Phosphate (P2O5) | 1.0% |
|---|---|
| Soluble Potash (K2O) | 1.0% |
| Humic Acid | 0.05% |
| Fulvic Acid | 0.009% |
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.
Fulvic acid is important because it helps nutrients stay available and move more efficiently into the plant, which can improve overall nutrient use and reduce hidden micronutrient issues. What makes it unique is its small, highly soluble structure that supports fast nutrient delivery differently than broader organic soil-building materials.
Humic acid is important because it improves root health and nutrient uptake by keeping minerals available, stabilizing the root zone, and supporting beneficial biology, which makes growth more consistent. It’s unique because it doesn’t act like a direct nutrient boost—its main power is improving the root environment so plants can use what’s already there more efficiently.
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.
Yes, it can if it pushes phosphorus too high or drives pH too low, because both conditions can reduce the plant’s ability to take up key micronutrients and calcium even when they’re present in the feed, which makes phosphoric acid uniquely powerful compared with slower, gentler phosphorus sources.
No, potassium hydroxide is mainly a strong pH-raising ingredient that changes how nutrients behave and how roots can access them, and its potassium addition is usually secondary. It’s important because stable pH prevents false deficiency symptoms and uptake stress, and it’s unique from other potassium sources because it’s used for acidity control rather than primarily for plant nutrition.
