Simple and easy to use, Hydro Fuel 4-Part Base Nutrient System provides great results but allows for more control and complexity later as a grower experiments and incorporates more additives into their feeding regimen. Sustainably formulated and manufactured, Hydro Fuel provides the necessary differentiation between the Grow and Bloom cycles with two parts for each stage of growth.

Hydro Fuel Bloom is used from the transition to the blooming and ripening stage of growth.
