House & Garden Top Booster 1L

Phosphorus and potassium are the two primary elements driving the plant's transition into and through the reproductive stage. Phosphorus supports energy transfer and flower site formation, while potassium regulates water movement, enzyme activity, and carbohydrate transport during heavy bloom. A targeted PK application at the right point in the flowering cycle amplifies the plant's biological response to its environment and drives a more intense and productive flowering period.

House & Garden Top Booster is a PK 13/14 flowering stimulator with the addition of EDDHA-Fe iron, which helps prevent chlorosis in flowering crops by providing a highly stable, pH-resilient iron source. The formulation works by reinforcing the plant's autumn hormone response, specifically ethylene, which signals the intensification of reproductive growth and promotes the formation of larger flowers and fruits. Top Booster is used for a single week in the middle of the reproductive stage as a concentrated trigger rather than a sustained feed.

Use four weeks before harvest for one week only. Do not combine with other PK boosters. Add after the base nutrient and adjust pH and EC to the plant's current stage.

Dose rate: 1.5 ml per litre.
