House & Garden Shooting Powder is a late-bloom pk flowering additive designed to help maximize flower yield by supporting key plant energy and oil-building processes. It’s a dry powder flowering additive and a flowering nutrient additive built for the finishing stretch of the bloom cycle.
Shooting Powder provides crucial nutrient precursors for atp synthesis, supporting the biological processes plants lean on when flowers are packing on weight. The formula is described as delivering readily available and soluble nutrients, helping maintain strong momentum late in flowering. That finish-focused nutrient availability is positioned to support faster growth, enhanced vigor, and higher yields when plants need extra push the most.
This late bloom booster is designed to initiate a secondary flowering phase, extending the plant’s natural drive to build more flower mass near the end of the cycle. It’s also intended to increase flower size and weight, giving a more substantial finish without changing the overall character of the crop. Alongside yield and density support, Shooting Powder is described as providing nutrient building blocks for the phospholipid bilayer, which is critical to oil synthesis—an important piece of finish quality tied to how plants build and store key compounds during bloom.
Shooting Powder is suited for late bloom and is designed to perform across all growth media, with compatible systems including hydroponics and soil. It’s also described as containing no synthetic pgrs and no detectable heavy metals, a clean-input detail many growers look for in a finishing additive. The key inputs are derived from phosphoric acid and potassium oxide, aligning with its role as a soluble pk for bloom that supports flower yield and finish-stage performance.
House & Garden Shooting Powder is a good fit for growers who want a clean, strong, and stable late-bloom pk flowering additive to support a secondary flowering phase, increase flower size and weight, and reinforce oil synthesis in soil or hydroponic setups.
Step-by-step mixing and feeding instructions for House & Garden Shooting Powder - 1 Satchet.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of House & Garden Shooting Powder - 1 Satchet 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.
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) 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.
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 oxide (K2O) is important because it shows how much potassium is available to support water control, sugar movement, and strong plant structure, which directly impacts growth quality and stress tolerance. It’s unique because K2O is mainly a label standard for potassium content, not a separate nutrient form the plant absorbs, so understanding it helps you avoid mixing up label numbers with real potassium needs.
