CANNA 9340025 Boost Accelerator 250-ml is powerful flowering stimulator. Specially developed for fast growing plants, it increases yields and improves quality. Boost stimulates the development of newly formed flowers which ultimately results in bigger, fuller fruits. Boost does not only assure excellent yields, but also better taste. Initially designed for reservoir mixing with nutrients, Boost can also be used as a foliar spray that the plant can absorb this flowering stimulant directly through the leaves. Adding PK 13/14 provides the plant with extra flowering elements while Boost ensures the plant has the energy to utilize these elements. Can be used in any type of grow media.
