House & Garden Top Shooter is a late-bloom pk flowering additive for an exceptional finish to the flowering cycle, designed to support flower growth right when plants need it most. This liquid bloom finisher nutrient additive focuses on high-quality potassium and phosphate to reinforce late-stage flowering performance.
Top Shooter provides nutrient precursors for key plant biological processes, including atp synthesis, helping plants keep building flower growth during late bloom. In addition to bloom support, it’s described for boosting the production of leaf and flower growth, supporting stronger vigor when flowering demand peaks. That makes it a practical choice for growers who want a finish-focused pk formula that stays simple while targeting the final stretch.
One of the most sought-after traits here is the way Top Shooter supports a secondary flowering phase. When plants are nearing the end of their flowering cycle, that “second push” support can matter for the final look and feel of the crop. Top Shooter is also designed to increase flower weight and density, giving a more substantial finish during the final bloom weeks without turning your program into a long checklist of add-ons.
Top Shooter is positioned as a highly bioavailable pk formula, built to deliver those finish-stage nutrients in a form plants can access efficiently. Beyond yield-focused goals, it also supports biological building blocks tied to the phospholipid bi-layer, which is critical to oil synthesis. That detail speaks to finish quality, not just size, since late-bloom plant processes influence how flowers mature and complete their development.
For flexibility across real-world setups, Top Shooter is suited for hydroponics and soil, and it’s described as performing in all growth media. It’s also a clean-input flowering additive: it contains no synthetic PGRs and no detectable heavy metals. The formula’s listed inputs are derived from phosphoric acid and potassium oxide, keeping the ingredients focused on its core purpose as a late-bloom pk flowering additive.
House & Garden Top Shooter is a good fit for growers who want a late-bloom additive that supports a secondary flowering phase, increases flower weight and density, and helps drive an exceptional finish to the flowering cycle in hydroponics, soil, or other media.
Step-by-step mixing and feeding instructions for House & Garden Top Shooter - 500 ML.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of House & Garden Top Shooter - 500 ML 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.
