FoxFarm Open Sesame Soluble Fertilizer 5-45-19 | 15lb Early Bloom Booster

The FoxFarm Open Sesame Soluble Fertilizer is a high-phosphorus bloom initiator specifically formulated to trigger vigorous blooming and bud development during the early weeks of flowering. With a 5-45-19 NPK ratio, FoxFarm Open Sesame Soluble Fertilizer delivers a targeted phosphorus surge directly to the root zone at the precise moment your plants transition into flower — setting the foundation for dense, productive bud sites throughout the entire bloom cycle.

Compatible with hydroponic systems, containers, and in-ground soil applications.
