GreenPlanet Hydro Fuel Bloom B (0-4-5)
GreenPlanet Hydro Fuel Bloom B (0-4-5) is a liquid base nutrient formulated specifically for the flowering stage. As Part B of GreenPlanet’s 4-Part Hydro Fuel nutrient system, it works alongside Hydro Fuel Bloom A to provide plants with a balanced range of macro and secondary nutrients throughout bloom.
With 4% available phosphate, 5% soluble potash, 1% magnesium, and 0.75% sulfur, Hydro Fuel Bloom B delivers targeted phosphorus, potassium, magnesium, and sulfur nutrition during flowering. Its two-part A and B format gives growers greater control over their nutrient program while remaining easy to mix and suitable for a wide range of growing systems.

Phosphorus and Potassium Nutrition for Flowering
GreenPlanet Hydro Fuel Bloom B (0-4-5) provides phosphorus and potassium to complement the nitrogen, potassium, calcium, and micronutrients supplied by Hydro Fuel Bloom A.
Phosphorus supports important plant processes related to energy transfer and flower development, while potassium contributes to nutrient movement and many essential plant functions. Magnesium and sulfur provide additional secondary nutrition to help maintain balanced plant development during flowering.
Designed to Work With Hydro Fuel Bloom A
The Hydro Fuel Bloom system separates flowering nutrition into Bloom A and Bloom B, allowing GreenPlanet to deliver a broader nutrient profile while maintaining formula stability.
Bloom B focuses on phosphorus, potassium, magnesium, and sulfur, while Bloom A provides nitrogen, calcium, potassium, and essential micronutrients. Together, the two components form the flowering portion of GreenPlanet’s Hydro Fuel 4-Part nutrient program.
For best results, use both components according to the current GreenPlanet Hydro Fuel Feed Program.
Simple Mixing and Application
GreenPlanet recommends using Hydro Fuel Bloom at approximately 3–4 mL/L / 11–15 mL/gal during the flowering stage.
Always add Bloom A to the water first and mix thoroughly before adding Bloom B. Do not mix the concentrated A and B formulas directly together before dilution.
Following the proper mixing order helps maintain nutrient compatibility and allows the formulas to disperse evenly throughout the nutrient solution.
Suitable for Multiple Growing Systems
GreenPlanet Hydro Fuel Bloom B can be used as part of the Hydro Fuel program in several cultivation methods, including:
- Hydroponic systems
- Drain-to-waste systems
- Recirculating systems
- Soil
- Soilless growing media
This versatility makes the Hydro Fuel Bloom system ideal for growers who want a flexible flowering nutrient program that adapts to different irrigation methods and growing environments.
Greater Control During Flowering
The GreenPlanet Hydro Fuel 4-Part system separates vegetative and flowering nutrition into Grow A, Grow B, Bloom A, and Bloom B formulas.
For growers who want more control over their nutrient program, GreenPlanet Hydro Fuel Bloom B provides the phosphorus, potassium, magnesium, and sulfur component of the flowering system. Used together with Bloom A, it creates a complete and adjustable base nutrient program for the flowering stage.
