Master Pack PRO Advanced Nutrients: Created by GrowLED for demanding growers!

Master Pack PRO Advanced Nutrients: The Ultimate Kit for Indoor Growing

Introduction: Have everything on hand for a successful harvest

When you start or want to optimize an indoor culture, the most difficult thing is often to choose the right fertilizers at the right time. Joseph, director of GrowLED, offers a simple solution in his presentation video: the Master PRO Advanced Nutrients Pack. This kit contains all the nutrients, boosters, and additives needed to take your plants from seed to harvest without any hassle. For growers who dream of a complete and consistent nutritional program, this pack is a worthwhile investment.

Behind this offer is the brand Advanced Nutrients, a pioneer in the specialty crop fertilizer market. The company, founded in Canada in 1996, has surrounded itself with scientists and offers more than 80 products. Its range is based on different types of inputs: micronutrients (Sensi Grow and Bloom), of the amino acids (Bud Candy), of the hormones and microorganisms (Tarantula), of the vitamins (B-52) and enzymes (SensiZym). All these products are tested under horticultural lamps and designed for hydroponic systems and substrate crops.

In this article, we will detail each element of the pack, explain their roles in growing and give practical tips to get the most out of this fertilizer kit. We will also see why the Master Pack PRO is a strategic asset for indoor growers and what are the best practices to optimize your harvests.

What's in the Advanced Nutrients PRO Master Pack?

The Master Pack PRO was designed by the GrowLED team to cover all phases of growth and flowering. It consists of four product families:

Category	Pack products	Main role
Basic fertilizer	Sensi Grow A–B, , Sensi Bloom A–B	Provides major mineral and microelements during the vegetative and flowering phases.
Root stimulators	Piranha, , Tarantula, , Voodoo Juice	Inoculate the substrate with beneficial fungi and bacteria to increase root surface area and nutrient uptake.
Flowering boosters	Bud Ignitor, , Big Bud, , Overdrive, , Bud Factor X	Specific stimulants to initiate flowering, increase the number and size of flowers, maximize resin and terpene production.
Supplements and additives	Rhino Skin, , B-52, , Tasty Terpenes, , Bud Candy, , SensiZym, , Flawless Finish	Strengthens tissues, provides vitamins, amino acids and sugars, improves aromas and simplifies rinsing at the end of flowering.

Each product is supplied in calibrated format (often 250 mL or 1 L) to cover a complete cycle on a conventional growing surface. The bottles are numbered to make it easier to follow the schedule. The advantage of this pack lies in the synergy between the formulas: the boosters and additives complement the Sensi Grow/Bloom bases to obtain vigorous plants and abundant harvests.

The Basics: Sensi Grow and Sensi Bloom (pH Perfect)

A 2-part system for balanced nutrition

The solutions Sensi Grow (vegetative phase) and Sensi Bloom (flowering phase) each consist of two parts (A and B). This duo ensures nutritional stability: part A provides calcium, nitrogen and magnesium, while part B provides phosphorus, potassium and microelements in precise quantities.

THE pH Perfect program is the key feature of these fertilizers. Thanks to a blend of chelates, humic/fulvic acids, and surfactants, it automatically maintains the pH of the nutrient solution in an ideal range. This allows plants to absorb nutrients without the need for pH adjustment. This technology is designed to work in a pH range of 4 to 8, making growing much easier for beginners.

Why choose Sensi Grow/Bloom?

• Complete formulation: Each bottle contains 16 carefully measured essential elements (macronutrients, micronutrients, amino acids). Chelates ensure rapid absorption.
• No pH adjustment: technology pH Perfect regulates acidity automatically.
• GrowLED Recommendations: Joseph recommends using 4 mL/L of Sensi Grow A and B during growth, then switching to Sensi Bloom A and B during flowering.

Root stimulators: creating a dynamic rhizosphere zone

Voodoo Juice: Bacteria to Boost the Root

Voodoo Juice brings four bacterial strains— Bacillus licheniformis, Bacillus pumilus, Bacillus subtilis And Paenibacillus polymyxa — that work in symbiosis with the plant. These microorganisms increase the root absorption surface area, improve nitrogen and phosphorus availability, and increase stress tolerance. Used during the first two weeks of growth and flowering (2 mL/L), Voodoo Juice encourages more vigorous plants.

Tarantula: 57 bacterial species for a rich microlife

Tarantula is a concentrated blend of 57 bacterial species (1.4 billion CFU per gram) that colonize the substrate. These bacteria act as extensions of the roots: they break down organic matter into available nutrients, strengthen natural defenses and promote higher yields. It is administered at 2 mL/L during the first two weeks of flowering.

Piranha: Mycorrhizal fungi at the service of roots

Piranha contains a powerful blend of endo- and ecto-mycorrhizal fungi. According to the manufacturer, these fungi can increase root surface area and length by up to 75% and improve nutrient absorption (86% more nitrogen, 234% more phosphorus). Mycorrhizae secrete growth hormones, improve soil structure, and act as biological control agents against pathogens. The product is 100% organic and can increase root volume by up to 700%, improving water and nutrient supply.

Bloom Boosters: Maximize Flower Yield and Quality

Bud Ignitor: Start flowering with a bang

Bud Ignitor is a early flowering stimulator Enriched with phosphorus, potassium, and kelp extracts. It prepares the plant for flowering, promotes flower bud formation, and provides vitamins and minerals that improve flavor and aroma. It is used during the first two weeks of flowering (2 mL/L).

Big Bud: Bulking Up Flowers and Increasing Terpenes

Big Bud is an iconic booster formulated with an optimal PK ratio and enriched with amino acids, ascorbic acid, and citric acid. These ingredients stimulate the production of proteins, terpenes, and secondary metabolites, resulting in bigger, heavier, and more fragrant flowers. Its recommended dosage is 2 mL/L from the 2nd to the 4th week of flowering.

Overdrive: Give a boost at the end of flowering

During the last weeks, Overdrive (NPK 1-5-4) provides an energy boost with bioavailable phosphorus and magnesium. It boosts flower and resin production during the late flowering period and allows plants to express their full genetic potential. The manufacturer recommends 2 mL/L during the last two weeks before flushing.

Bud Factor X: Continuous Resins and Terpenes

Bud Factor X is a biostimulant that boosts resin production from the first days of flowering. It improves flavor and aroma by increasing terpene biosynthesis. Its formulation includes nitrogen and B vitamins to support growth and strengthen roots. Its use (2 mL/L from the 1st to the penultimate week of flowering) ensures optimal quality.

Supplements and additives: strengthen, sweeten and purge

Rhino Skin: The power of silicate

Rhino Skin provides potassium silicate Highly bioavailable. Silicon strengthens cell walls, thickens stems, and improves resistance to disease, insects, and stress. Plants can then support heavier flowers. It is dosed at 2 mL/L from the 1st to 6th week of flowering.

B-52: A cocktail of B vitamins

B-52 provides a complex of B vitamins (B1, B2, B3, B5, B7, B9) combined with humates. These vitamins play several roles: folate (B9) improves crop weight and quality; vitamin B5 participates in cellular processes; vitamin B1 (thiamine) helps convert carbohydrates and improves phosphate utilization, activates systemic resistance and promotes root development. Other vitamins (B2, B3, B7) strengthen immunity and energy production. B-52 is used throughout the cycle (2 mL/L) and can be sprayed or applied as a watering.

Tasty Terpenes: More flavor and resin

Formerly known as Nirvana, Tasty Terpenes is an organic stimulator that combines amino acids, seaweed (kelp), alfalfa meal, bat guano, vitamins and plant extracts. This mixture enriches the plant with micronutrients and promotes flower development, stimulates terpene production and increases yield. Thanks to its potassium content, it strengthens the stems and improves photosynthetic absorption. It is used regularly (2 mL/L) from the beginning to the end of flowering.

Bud Candy: Sugars for Sweet Flowers

Bud Candy provides carbohydrates, amino acids, and vitamins that fuel microorganisms and plants. The sugars feed beneficial bacteria in the root zone and enhance the synthesis of terpenes and flavonoids. Although the manufacturer's website is difficult to access, user feedback indicates that Bud Candy intensifies the sweetness and aroma of flowers. It is recommended throughout the flowering period at a dose of 2 mL/L.

SensiZym: Recycling root waste

SensiZym is a blend of enzymes (xylanase, cellulases, beta-glucanase) that breaks down dead organic matter in the root zone, converting it into available nutrients. By breaking down debris, it releases nutrients while reducing the risk of pathogens. Growers find that these enzymes help reuse the substrate (rockwool, coconut, etc.), avoiding the need to purchase and treat new media. SensiZym is dosed at 2 mL/L throughout the flowering phase.

Flawless Finish: a clean and tasty end to the cycle

The final step in a successful culture is rinsing. Flawless Finish is a cleaning agent that removes excess nutrients and heavy metals before harvest. Using chelate technology, it captures unwanted metals and ions, removing them from the plants, and ensuring a clean end product. The manufacturer states that this biostimulant:

• Removes pollutants, heavy metals and fertilizer salts to preserve aromas;
• uses chelates to capture and extract harmful ions;
• removes nitrates and sulfates thanks to stabilized chelates and magnesium sulfate;
• improves sugar content in flowers by increasing the ideal C/N ratio;
• provides just the right amount of magnesium to complete ripening and removes nitrogen in time to maintain yields.

Flawless Finish is used during the last week before harvest: simply water with 2 mL/L for 6 hours then rinse with clean water.
