Understanding the Feed Program: Hydro Fuel

GreenPlanet Nutrients makes four different and distinct feed programs. Made for the medicinal gardener, the 1-Part Medi-One feed program is an organic system that offers plants a wide variety of bio-available elements. The 2-Part Dual Fuel program is GreenPlanet’s simplest and most concentrated formula. The 3-Part program, GP3, was designed to be intricate and balanced, made for the seasoned grower with an established routine. The 4-Part Hydro Fuel system is GreenPlanet’s final feeding program. Coming in four parts, the base nutrient component of Hydro Fuel is made for the easy-going traditional grower – someone who wants the complexity of a multipart feed program, but with none of the effort. If you’re thinking about purchasing GreenPlanet’s Hydro Fuel feed program, read the following passages for more information. 

What is a Feed Program?

A feed program is a schedule of plant nutrition that can be mapped in terms of fertilizer dosage, ratio, supplementation, and use over time. Usually containing several bottles, a complete feeding program should contain supplements including a base nutrient fertilizer, a vitamin supplement, a bloom booster, a source of carbohydrates, and a trichome enhancer. By combining these inputs into a feeding program, growers can expect to produce the most quality-driven harvest possible. To browse a complete list of feed programs available at GreenPlanet Nutrients, click here. Or, read the blog below for advice on choosing a GreenPlanet feed program.

GreenPlanet’s 4-Part Hydro Fuel Feed Program

GreenPlanet’s 4-Part Hydro Fuel base nutrient system gives growers extreme control over both vegetative and flowering growth with two specific and balanced formulas for each stage of production. The base nutrient component comes in four parts, A&B Grow and A&B Bloom, two formulas for each stage of growth. But don’t let the excess of nutrients fool you into thinking Hydro Fuel is complicated – GreenPlanet’s 4-Part feed program is one of the simplest, yet most effective nutrient systems on the market. Here’s more information on each part of the Hydro Fuel feed program: 

Base Nutrients

Additive Nutrients

Hydro Fuel Grow A&B

Hydro Fuel Grow A&B are the growing components of GreenPlanet’s 4-Part base nutrient system. Designed to be used together in equal ratios throughout the vegetative stage, Hydro Fuel Grow A&B provides your crop with a diverse range of micro, macro, and secondary nutrients. For example, Hydro Fuel Grow A is the nitrogen and micronutrient heavy part of the vegetative A&B program. It gives plants clean access to micronutrients like boron, cobalt, molybdenum, zinc, and chelated sources of iron and manganese. Furthermore, the B component of Hydro Fuel Grow compliments this formula perfectly by being packed full of phosphorus and potassium, two nutrients that encourage rapid root growth and cellular expansion. 

Hydro Fuel Bloom A&B

Hydro Fuel Bloom A&B are the blooming components of GreenPlanet’s 4-Part base nutrient system. The Bloom A&B pair provides your plants with elements that encourage the expression and expansion of fully formed, dense flowers. For instance, Hydro Fuel Bloom A is made with balanced levels of nitrogen and micronutrients to ensure your plants stay healthy and free of common nutrient deficiencies during the flowering stage. Hydro Fuel Bloom B, however, is loaded with aggressive amounts of phosphorus and potassium. Bloom A&B guarantees the maximal expression of flowers during the blooming period by providing gardeners with access to an easy-to-use and balanced fertilizer. 


Vitathrive is GreenPlanet’s vitamin supplement. Use Vitathrive aggressively throughout the vegetative stage, on transplant day, and during any periods of stress to increase root growth, reduce internal stress, and strengthen any plant’s immune response. Also, the main supplementary component of Vitathrive, Thiamine or vitamin B1, has been shown in old and recent research to be a factor in a plant’s diet that reduces fungal disease and plant stress (Subki et al, 2018, p. 37).

Massive Bloom Formulation

Massive Bloom Formulation is GreenPlanet’s premier flowering additive. It’s formulated with all of the necessary macro and microelements required to increase flower size and weight. As well as providing several additional beneficial properties, such as L-amino acids and a source of carbohydrates, Massive is the perfect blooming supplement to pair with the select and aggressive Hydro Fuel base nutrient system.


Entourage Effect: The theory that the synergistic effect of THC, flavonoids, cannabinoids, and terpenes all contribute to the overall “experience” of cannabis consumption. 

Rezin is GreenPlanet’s flowering additive formulated to enhance the natural processes within flowering plants that produce flavor and aroma. With no PPM, Rezin can be used with any base nutrient program until harvest to produce large, sugar-coated flowers. Now known for enhancing the “entourage effect” (Russo, 2019, para. 17), Rezin is one proprietary supplement that is a must-have for any quality-driven garden. 

Liquid Weight

Liquid Weight is a supplement blend of simple carbohydrates that supports beneficial microbial life in the root zone. This leads to an increase in the absorption of essential nutrients that help develop impressive aromatic flowers and fruits. Plants spend an amazing amount of energy-releasing sugars like cellulose into the root zone. So, by supplementing your plant’s expenditures with additional carbs, you can be sure the beneficial microbes in your soil will be plentifully fed. For more information on the benefits of sugars in the garden, read our blog: The Power of Carbohydrates in the Garden. 

Using the Feed Program

Like a recipe, the Hydro Fuel feeding program has the best results when the formula is followed. A feed program is a schedule of plant nutrition that can be mapped in terms of fertilizer dosage, ratio, supplementation. So, throughout the weeks of vegetative and flowering growth, the Hydro Fuel feeding program will guide the grower through different stages of a plant’s life. It will also offer general feeding ratios, doses, and helpfully supplementation tips. All the measurements of plant food on GreenPlanet’s feeding programs are described in milliliters of fertilizers per liter of water.

Features and Considerations

Here are some features to consider about the Hydro Fuel feed program. First, GreenPlanet only recommends certain products and supplements for specific stages of plant growth. For example, the feeding program is split into two stages: vegetative and flowering growth. In these different stages, only certain supplements are recommended for use. For instance, you’ll notice that products that increase flower size, like Massive Bloom Formulation, are only introduced in the second week of the flowering stage.

Also, Hydro Fuel is fed in equal ratios throughout vegetative and flowering stages and growth. So, no matter the stage of growth, you can expect to add equal amounts of Hydro Fuel A&B. This makes mixing Hydro Fuel a breeze. Also, mixing a 1:1 ratio fertilizer means that growers need only buy equal amounts of Hydro Fuel A&B. When used correctly, both parts of Hydro Fuel will run out at the same time. This feature of the 4-Part feed program saves growers time, money, and waste. 

Tips on Using Hydro Fuel

Another aspect of the Hydro Fuel feed program to examine is the rise and gradual plateau of the recommended Parts Per Million (PPM) of your nutrient solution. PPM is a unit of measurement which describes the concentration and strength of a nutrient solution.

PPM is a unit of measurement which describes the concentration of a solution.

While following the Hydro Fuel feeding program, you’ll notice that the PPM of you’re nutrient solution will gradually increase as you move into the flowering stage, finally plateauing in weeks 2 – 6, followed by a gradual decrease in strength as you move towards the final weeks of flush. These general measurements are based on the assumption that as time progresses, your plants will become larger, and therefore be able to digest a more concentrated nutrient solution. However, these nutrient levels generally plateau and decrease as plants ripen and move towards the flushing stage. For a more in-depth understanding of PPM and plant nutrition, refer to the blog titled: Understanding Plant Nutrition And Factors That Influence Availability.
