House & Garden Top Booster - 1 Litre

House & Garden Top Booster is a pk flowering additive for mid bloom that supplements the flowering process by supporting floral production when plants are directing energy to flowering sites.

Designed around premium phosphorus and potassium, Top Booster supports the plant in the final stage of reproductive growth with available and soluble nutrients that keep flowering performance moving forward. As upward growth is arrested and more resources are naturally pushed into flower development, this floral nutrient supplement helps reinforce the flowering process without adding complexity to the base program.

Top Booster’s nutrient profile is positioned to support key plant processes required for adapting to a changing light environment, helping plants stay productive as they shift deeper into bloom. In the canopy and root zone, that shows up as clearer priorities: it directs energy to flowering sites, improves plant strength and resilience, and boosts nutrient uptake efficiency so plants can stay steady through the demanding mid-bloom window. When flowering sites are asking for more, Top Booster is built to help plants support vigorous flower growth and achieve higher yields, with a finish that also enhances harvest yield and aroma.

For growers who want clean inputs, Top Booster contains no synthetic PGRs and no detectable heavy metals. Its listed inputs are derived from potassium hydroxide and phosphoric acid anhydride, keeping the formula focused on the core pk support it’s known for rather than a long list of extras. If you’re choosing a bloom-phase pk additive, this tight ingredient story is a practical advantage: the product stays purpose-driven, predictable, and easy to slot into a flowering routine.

Top Booster works in all growing media and is presented as suitable for hydroponics and soil, making it a flexible choice across common setups while staying stage-specific to mid bloom. It’s a good fit for growers who want a targeted pk flowering additive that reinforces the flowering process, supports floral production with available and soluble nutrients, and helps keep energy and nutrients concentrated where flowers are forming.
