Description
GreenPlanet Dual Fuel Part 2 – 0-3-6 Base Nutrient
Concentrated Phosphorus & Potassium Base Nutrient for Grow & Bloom
GreenPlanet Dual Fuel Part 2 is the second component of GreenPlanet's highly concentrated Dual Fuel 2-Part Base Nutrient System, formulated to work alongside Dual Fuel Part 1 throughout the complete vegetative and flowering cycle.
With an NPK analysis of 0-3-6, Dual Fuel Part 2 provides higher levels of phosphorus and potassium, along with magnesium and sulfur, to complement the nitrogen, calcium, and supporting nutrients supplied by Dual Fuel Part 1. Together, the two products provide a complete spectrum of macro, micro, and secondary nutrients required for healthy plant development.
Dual Fuel is built around simplicity. Part 1 and Part 2 are used in equal amounts throughout the entire crop cycle, removing the need for complicated Grow and Bloom base nutrient ratios.
Highly concentrated and completely water soluble, Dual Fuel is ideal for hydroponics, coco, drain-to-waste, recirculating, soil, and soilless cultivation systems.

Complete Part 2 Nutrition
Dual Fuel Part 2 provides the phosphorus and potassium-rich half of the GreenPlanet Dual Fuel programme.
While Dual Fuel Part 1 delivers higher levels of nitrogen and calcium, Part 2 contributes the phosphorus, potassium, magnesium, and sulfur required to complete the mineral profile.
The result is a two-part nutrient programme that can remain consistent from vegetative growth through flowering.
Rather than changing the ratio between the two bottles, growers simply adjust the overall concentration according to plant size, growth stage, cultivar, and feeding requirements.
What Does Dual Fuel Part 2 Provide?
Phosphorus
Dual Fuel Part 2 contains 3% available phosphate (P₂O₅).
Phosphorus is involved in several essential plant processes, including:
- Photosynthesis
- Root development
- Energy transfer
- Nutrient movement
- Plant metabolism
- Flower development
Maintaining adequate phosphorus availability is particularly important as plants establish strong root systems and transition into reproductive growth.
Potassium
Dual Fuel Part 2 contains 6% soluble potash (K₂O), making potassium a major component of the formulation.
Potassium contributes to:
- Plant energy utilisation
- Water regulation
- Nutrient transport
- Cell strength
- Plant resilience
- Flower development
- Overall crop performance
GreenPlanet specifically formulates Part 2 with higher potassium levels to complement the nitrogen-rich Part 1 formula.
Magnesium
Dual Fuel Part 2 contains 1.5% water-soluble magnesium.
Magnesium is an essential component of chlorophyll and therefore plays an important role in photosynthesis and healthy plant development.
Sulfur
The formulation also provides 2.5% combined sulfur.
Sulfur contributes to essential plant metabolic processes and works alongside the other macro and secondary nutrients supplied by the Dual Fuel system.
Guaranteed Analysis
| Nutrient | Analysis |
|---|---|
| Available Phosphate (P₂O₅) | 3.0% |
| Soluble Potash (K₂O) | 6.0% |
| Magnesium (Mg) | 1.5% |
| Water-Soluble Magnesium | 1.5% |
| Sulfur (S) | 2.5% |
| Combined Sulfur | 2.5% |
The mineral sources used in Dual Fuel Part 2 include potassium sulfate, monopotassium phosphate, and magnesium sulfate.
Dual Fuel Part 1 + Dual Fuel Part 2
Dual Fuel is designed as a complete two-part base nutrient system.
Dual Fuel Part 1 – 5-0-1
Provides higher levels of nitrogen and calcium, along with supporting micronutrients.
Dual Fuel Part 2 – 0-3-6
Provides higher levels of phosphorus and potassium, together with magnesium and sulfur.
Used Together
When Part 1 and Part 2 are combined correctly in the nutrient reservoir, they provide the comprehensive macro, micro, and secondary nutrient profile required throughout the plant life cycle.
Simple 1:1 Mixing Ratio
One of the major advantages of GreenPlanet Dual Fuel is its straightforward feeding system.
Dual Fuel Part 1 and Dual Fuel Part 2 are always used in equal amounts.
There is no need to alter the Part 1-to-Part 2 ratio when moving from vegetative growth into flowering.
| Dual Fuel Part 1 | Dual Fuel Part 2 | Water |
|---|---|---|
| 0.5mL | 0.5mL | 1L |
| 1.0mL | 1.0mL | 1L |
| 1.5mL | 1.5mL | 1L |
| 2.0mL | 2.0mL | 1L |
| 2.5mL | 2.5mL | 1L |
Use 0.5–2.5mL/L of each part, adjusting overall strength according to plant requirements.
Important Mixing Instructions
Never mix concentrated Dual Fuel Part 1 and Dual Fuel Part 2 directly together.
The concentrated products should always be diluted separately into the nutrient reservoir.
For correct preparation:
- Fill the reservoir with water.
- Add the required amount of Dual Fuel Part 1.
- Mix thoroughly.
- Add the same amount of Dual Fuel Part 2.
- Mix thoroughly again.
- Add compatible supplements individually if required.
- Check the final EC/PPM.
- Check and adjust pH as required.
Directly combining Part 1 and Part 2 in their concentrated form can cause mineral precipitation and nutrient lockout.
Suitable Growing Systems
GreenPlanet Dual Fuel Part 2 is suitable for use as part of the Dual Fuel programme in:
- Hydroponics
- Coco coir
- Coco/perlite
- Drain-to-waste systems
- Recirculating hydroponics
- Soil cultivation
- Soilless substrates
- Indoor cultivation
- Automated irrigation systems
- Commercial fertigation systems
Its water-soluble mineral formulation makes it particularly useful in applications where clean, consistent nutrient delivery is important.
Designed for Vegetative Growth & Flowering
Although Part 2 contains higher levels of phosphorus and potassium, it is not simply a flowering additive.
Dual Fuel Part 2 forms an essential part of the base nutrient programme throughout both vegetative growth and flowering.
During vegetative growth, phosphorus supports root development and fundamental energy processes, while potassium contributes to plant metabolism and structural development.
As plants transition into flowering, these same elements continue supporting increasingly demanding reproductive growth.
This means growers don't need to introduce Dual Fuel Part 2 only when flowering begins—it is designed to be used alongside Part 1 throughout the complete feeding programme.
Ideal for Flowering Development
Dual Fuel Part 2's 0-3-6 NPK profile provides a phosphorus and potassium-rich complement to Part 1.
During flowering, these nutrients support the biological processes associated with:
- Flower initiation
- Flower development
- Plant energy transfer
- Nutrient transportation
- Photosynthetic activity
- Cell strength
- Overall crop development
The formulation provides this nutritional support while maintaining the simplicity of the Dual Fuel 1:1 base nutrient system.
Commercial-Grade Simplicity
Using equal quantities of Part 1 and Part 2 throughout the crop cycle makes Dual Fuel particularly practical for commercial cultivation.
The straightforward ratio helps:
- Simplify reservoir preparation
- Reduce measurement errors
- Simplify staff training
- Improve feeding consistency
- Streamline nutrient calculations
- Support automated dosing systems
- Simplify injector configurations
- Reduce unnecessary nutrient complexity
The same benefits also make Dual Fuel an excellent choice for smaller hobby and home cultivation systems.
