Quick Answer
Grotek Blossom Blaster is a concentrated 0-48-31 flowering-stage powder for hydroponic growing. It supplies phosphorus and potassium from monopotassium phosphate to support early flower development. Mix 1 g per 10 L of water, apply once before bud break, then repeat once two weeks later.
Product Description
Grotek Blossom Blaster is a highly concentrated bloom additive designed for the early flowering phase. The current official Grotek formulation has a guaranteed analysis of 0-48-31: 48% available phosphoric acid (P2O5) and 31% soluble potash (K2O).
Phosphorus supports plant structure and vigour, while potassium supports the movement of water, nutrients and carbohydrates through the plant. Grotek recommends Blossom Blaster before bud break to support flower set. It is a supplement, not a complete base nutrient.
