Power SI Original is a concentrated silica biomix silica supplement for increased nutrient uptake and sturdier plant growth with highly bioavailable silica.
Built as a proprietary concentrated silica biomix, Power SI Original combines highly bioavailable silica with micro and macro nutrients to support day-to-day crop performance. It carries a light 1-3-1 NPK profile, keeping it easy to place in a nutrient plan without turning it into a heavy base feed. For a compact facts layer, it includes soluble silicon derived from potassium silicate, with key inputs that include urea, phosphoric acid, and sodium molybdate.
The core performance focus is increased nutrient uptake and increased bioavailability. By supporting nutrient absorption and nutrient bioavailability, Power SI Original is positioned for more efficient use of the nutrients already present in a plant’s environment. That transporter-style role is paired with structural support, helping to build stronger cell walls for stronger, healthier plants with thicker stalks and stems.
Power SI Original is also designed to encourage faster rooting times, which can support more confident early establishment in propagation and transplant workflows. In ongoing production, it helps to reduce salt build up and dehydration of your crops, supporting a steadier root-zone environment when conditions trend dry or input levels fluctuate.
Environmental swings can show up in the canopy fast, and Power SI Original also helps to correct the elongation of internode spacing tied to environmental stress and nutrient imbalance. That internode-spacing support helps keep growth looking more even and controlled, especially when plants are pushing hard.
Power SI Original is a good fit for growers who want highly bioavailable silica with a light NPK profile, plus support for thicker stalks and stems, encourage faster rooting times, and increased nutrient uptake across demanding crop cycles.
Step-by-step mixing and feeding instructions for Power Si Original - 1 Litre.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Power Si Original - 1 Litre 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.

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.

| Urea Nitrogen (N) | 1.0% |
|---|---|
| Available Phosphate (P2O5) | 3.0% |
| Soluble Potash (K2O) | 1.0% |
| Molybdenum (Mo) | 0.008% |
| Soluble Silicon (Si) | 2.21% |
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.
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.
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.
Soluble silicon is important because it strengthens plant tissues and improves stress tolerance, helping plants stay upright, conserve water better during heat or drought, and handle disease and pest pressure more effectively. It’s unique from most nutrients because it doesn’t mainly “feed” growth directly; it helps plants protect and reinforce the growth they’re already building.
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.
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.
Potassium silicate is mainly used for silicon, because the silicate portion helps plants build tougher tissues and handle stress better, while the potassium is usually a secondary contribution. It’s unique because it can improve plant structure while also strongly raising root-zone pH, so it needs more care than most similar inputs.
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.

Fire stuff!
The best mono acid great price too!
