Bud Fuel

Grotek Bud Fuel Pro is a 100% soluble flowering stimulator with a 1-3-4 NPK ratio designed for use during the pre-flowering and early flowering stages of cannabis cultivation. It improves the availability of nutrients in the substrate for explosive flowering, accelerating nutrient absorption and improving general bud development from the moment flowering begins.

The combination of phosphorus and potassium in the 1-3-4 ratio drives the initial flower set and bud site development that determines overall yield potential — plants that get a strong start in early bloom tend to produce more and denser flowers. Grotek sources potassium from multiple forms for optimal plant availability.

Being fully soluble, Bud Fuel Pro works in all growing systems — soil, coco, and hydroponic — and dissolves completely in water without residue. Apply from the first week of pre-flowering through early bloom as part of Grotek's recommended feeding program. Compatible with their full nutrient lineup and works well as a flowering initiator alongside any complete base nutrient system.
