  • House and Garden Top Booster 5L

    Top Booster House & Garden Top Booster is an excellent flowering stimulator which acts on the basis of potassium and phosphorus and Eddha-Fe (iron). These elements are important for the plant's flowering; potassium for the beginning of the flowering stage and phosphorus for the proper development of fructification, while the Eddha-Fe additive ensures a better coloring of the leaves.

    H&G Top Booster creates an optical drought giving the plant the impression that the last phase of its life cycle has started. To ensure its survival, the plant will therefore begin forming flowers and fruits to reproduce. Add Top Booster for two to three days and then return to the usual nutrient composition. The plant will continue to form fruits and flowers. As this aspect of the final phase of the plant's cycle starts earlier, the fruits and flowers have more time to become larger.

    Application

    Use Top Booster 3 weeks before the end of flowering, for only 3 to 4 days. This will coincide with the last three to four days in the final week you use MultiZyme, before you switch to BudXL and Shooting Powder. This is the period that the plant is in its prime and can optimally make the transition from growth to flowering and frutification.

    Dosage: 5.7 ml per gallon of water.

    Notice: NEVER use Top Booster in combination with "PK 13-14", Top Shooter or Shooting Powder.
