GreenPlanet Nutrients 4-Part Hydro Fuel Kit

The GreenPlanet Nutrients 4-Part Hydro Fuel Kit is a complete starter nutrient kit designed for growers who want a flexible, stage-specific feeding program from early vegetative growth through flowering. Built around GreenPlanet’s Hydro Fuel 4-part base nutrient system, this kit provides dedicated formulas for both the grow and bloom stages, plus premium additives to support plant development, flowering performance, aroma, flavour, and overall vitality.

Hydro Fuel gives growers more control than a simple one-part nutrient program. With Grow A, Grow B, Bloom A and Bloom B, plants receive different base nutrition during vegetative growth and flowering. This makes the GreenPlanet 4-Part Hydro Fuel Kit a strong choice for indoor gardens, hydroponic systems, coco, soil, soilless media, greenhouses and professional cultivation programs.

Complete 4-Part Base Nutrient System

The GreenPlanet Hydro Fuel system uses four separate base nutrients to support plants through different growth stages. Hydro Fuel Grow A and Grow B are used during the vegetative stage, while Hydro Fuel Bloom A and Bloom B are used during the flowering stage.

This separation allows growers to adjust nutrition more precisely as plants move from active green growth into bloom production. For growers who want more flexibility, the 4-part format helps create a more controlled feeding routine.

  • Hydro Fuel Grow A – Part A vegetative base nutrient
  • Hydro Fuel Grow B – Part B vegetative base nutrient
  • Hydro Fuel Bloom A – Part A flowering base nutrient
  • Hydro Fuel Bloom B – Part B flowering base nutrient

Base Nutrients and Additives in One Kit

The GreenPlanet Nutrients 4-Part Hydro Fuel Kit gives growers the core Hydro Fuel base nutrient system plus selected additives to support key stages of growth. The grow formulas help support vegetative development, while the bloom formulas provide stage-specific nutrition for flowering plants.

The included additives help round out the feeding program. Vitathrive supports early plant development and vegetative health, Massive Bloom supports flowering performance, Rezin helps enhance natural aroma and flavour expression, and Liquid Weight provides carbohydrates to support plant energy and beneficial microbial activity in the root zone.
