NPK Industries RAW Variety Pack – 12-Piece Nutrient Kit

The NPK Industries RAW Variety Pack is a twelve-piece collection of concentrated water-soluble nutrients, minerals, biostimulants, and plant supplements. Each product is packaged separately, allowing growers to test individual inputs, correct specific nutrient shortages, or develop a customized feeding program without purchasing twelve full-size products.

The kit includes primary nutrients, secondary minerals, amino acids, botanical extracts, wetting agents, carbohydrates, and humic substances for use in soil, coco coir, soilless media, and hydroponic systems. Because every component remains separate, growers can select only the products appropriate for their plants, water, growing medium, and existing fertilizer program.

What Is Included

The RAW Variety Pack contains one 2-ounce pouch of each of the following products:

• RAW Potassium: A concentrated potassium source for water regulation, nutrient transport, plant metabolism, and flower or fruit development.
• RAW Calcium/Mag: Supplies calcium and magnesium to support cell development, root growth, chlorophyll production, and photosynthesis.
• RAW Yucca: A natural wetting-agent and surfactant product that helps water and nutrient solutions spread more evenly through growing media.
• RAW Humic Acid: A leonardite-derived humic supplement that supports growing-medium performance, mineral interaction, and root-zone nutrient availability.
• RAW Full-Up: A water-soluble fulvic acid supplement that supports mineral mobility and nutrient uptake.
• RAW Cane Molasses: A powdered carbohydrate source formulated to support beneficial microbial activity without the handling difficulties of liquid molasses.
• RAW Nitrogen: A concentrated 20-0-0 ammonium nitrogen supplement for vegetative feeding and targeted nitrogen adjustment.
• RAW Phosphorus: A concentrated phosphorus fertilizer for custom nutrient recipes and periods of increased phosphorus demand.
• RAW B-Vitamin: Combines vitamin B1 with magnesium and sulfur to support chlorophyll production and plant performance during stressful growth periods.
• RAW OminA: A plant-protein hydrolysate containing naturally derived amino acids and nitrogen for plant metabolism and custom feeding programs.
• RAW Kelp: A water-soluble seaweed extract derived from Ascophyllum nodosum that supplies botanical compounds and soluble potassium.
• RAW Silica: A concentrated silica supplement formulated to support strong plant tissues, stems, branches, and structural resilience.

RAW OminA and RAW Amino Acids are separate NPK Industries products. This variety pack includes RAW OminA unless the physical package indicates otherwise.

Key Benefits

• Twelve products in one kit: Provides a broad selection of RAW nutrients and supplements for trial use and custom recipe development.

• Targeted deficiency support: Allows specific nutrients to be added without automatically increasing every element in the reservoir.
• Custom nutrient development: Suitable for growers learning to formulate or refine crop-specific feeding programs.
• Trial-size convenience: Makes it possible to evaluate individual RAW products before purchasing larger quantities.
• Water-soluble powders: Designed for clean mixing in irrigation water, nutrient solutions, and compatible hydroponic reservoirs.
• Soil, coco, and hydro compatibility: Supports multiple growing methods and established fertilizer programs.
• Minerals and biostimulants: Includes primary nutrients, secondary minerals, amino acids, botanical extracts, carbohydrates, humic substances, fulvic acid, and silica.
• Flexible growth-stage use: Contains products applicable to vegetative development, flowering, fruiting, root-zone support, and environmental stress management.
• Compact nutrient library: Keeps multiple concentrated inputs available without storing numerous full-size containers.

What This Kit Is Designed For

The RAW Variety Pack is especially useful for:

• Growers testing the RAW product line
• Small gardens and limited plant counts
• Custom fertilizer formulation
• Soil, coco, and hydroponic recipe development
• Comparing individual supplements
• Correcting identified nutrient shortages
• Adjusting an existing base fertilizer
• Developing crop- or cultivar-specific feeding schedules
• Growers who want more control than an all-in-one fertilizer provides

This kit can also help growers learn how individual nutrient elements and biostimulants affect their program when introduced methodically.

Not an All-in-One Fertilizer

The RAW Variety Pack should not be treated as a premeasured complete fertilizer system. The twelve products perform different functions, and they are not intended to be mixed together indiscriminately.

Some products supply concentrated fertilizer elements, while others function as:

• Biostimulants
• Wetting agents
• Carbohydrate sources
• Amino acid supplements
• Humic or fulvic substances
• Structural plant supplements

Use a complete base fertilizer unless following a properly calculated custom nutrient recipe. Adding all twelve products to an already complete fertilizer can cause excessive EC, nutrient imbalance, pH instability, or unnecessary product overlap.

How to Use

Every product in the variety pack has its own concentration, application rate, and recommended timing. Follow the directions on each individual pouch or the applicable NPK Industries feeding chart.

A responsible testing process is:

1. Begin with a stable base nutrient or established fertilizer program.
2. Identify the specific nutrient, biological, or growing-medium goal.
3. Select the RAW product that addresses that goal.
4. Begin at the lowest applicable label rate.
5. Introduce one new product at a time whenever possible.
6. Record the dosage, date, crop stage, EC or PPM, pH, and plant response.
7. Evaluate the results before adding another product or increasing the rate.

Testing products individually makes it easier to determine which input produced a beneficial or undesirable response.

Recommended Mixing Instructions

1. Fill the reservoir or watering container with clean water.
2. Add and completely dissolve the required base fertilizer.
3. Measure the selected RAW product according to its individual directions.
4. Dissolve the RAW powder separately into the nutrient solution.
5. Add additional products one at a time, mixing thoroughly between additions.
6. Measure the final EC or PPM.
7. Check and adjust pH after the fertilizer program is completely mixed.
8. Apply the finished solution according to the crop and growing medium.

Never combine undiluted fertilizer concentrates or concentrated dry powders directly with one another. Always disperse each product into water before introducing the next component.

Building a Custom Nutrient Program

Experienced growers can use the pack’s Nitrogen, Phosphorus, Potassium, and Calcium/Mag products to alter the mineral profile of a feeding program. However, a complete fertilizer recipe must also account for:

• Total elemental concentration
• Nitrogen forms
• Calcium-to-magnesium balance
• Phosphorus and potassium levels
• Sulfur requirements
• Micronutrients
• Source-water mineral content
• Crop stage
• Growing-medium properties
• Target EC or PPM
• Root-zone pH

Do not build a fertilizer recipe using only the front-label N-P-K numbers. Those numbers describe fertilizer analysis by weight and are not direct mixing ratios.

Using the Pack With an Existing Base Fertilizer

The RAW products can supplement many complete fertilizer programs. Before adding anything, review the guaranteed analysis of the base fertilizer to determine what it already provides.

For example:

• Do not add RAW Nitrogen automatically when the base formula already supplies adequate nitrogen.
• Do not add RAW Calcium/Mag unless water quality, growing medium, plant demand, or symptoms indicate a need.
• Do not stack RAW Phosphorus or Potassium onto a strong bloom formula without calculating the resulting concentration.
• Use RAW Silica as a structural supplement rather than as a replacement for complete plant nutrition.
• Treat RAW Kelp, Humic Acid, Full-Up, OminA, and B-Vitamin as supplements rather than complete fertilizers.

Monitor the total EC or PPM whenever concentrated mineral products are added.

Mineral Nutrients and Biostimulants

The variety pack contains two broad product categories:

• Mineral nutrients: Nitrogen, Phosphorus, Potassium, and Calcium/Mag directly contribute fertilizer elements to the nutrient solution.
• Supplements and biostimulants: Yucca, Humic Acid, Full-Up, Cane Molasses, B-Vitamin, OminA, Kelp, and Silica perform specialized supporting roles.

Not every biostimulant is an ionic nutrient. These products may influence wetting, mineral mobility, microbial activity, plant metabolism, or growing-medium performance without functioning as complete sources of plant nutrition.

Soil and Coco Coir Use

For soil and coco applications:

• Add selected products to irrigation water or a completed nutrient solution.
• Mix until fully dispersed or dissolved.
• Monitor input and runoff EC or PPM.
• Check root-zone or runoff pH periodically.
• Avoid adding multiple concentrated products in response to symptoms without first identifying the cause.
• Maintain appropriate irrigation frequency and drainage.

Coco coir may require additional attention to calcium, magnesium, potassium, and runoff management, but supplementation should still be based on the complete fertilizer program.

Hydroponic Use

The RAW powders are suitable for compatible hydroponic systems when used at their individual label rates. Completely dissolve every selected product before adding it to the reservoir.

Products containing carbohydrates, botanical extracts, humic substances, or wetting agents may change reservoir appearance, foaming, or biological activity. Maintain:

• Adequate circulation
• Appropriate dissolved oxygen
• Clean pumps and filters
• Stable solution temperature
• Regular reservoir inspection
• Suitable system sanitation

RAW Cane Molasses and other biological-support products may not be appropriate for every sterile-reservoir program.

Foliar Application

Several products in the kit may be foliar compatible, but they do not share one universal spray rate. Follow the individual package directions for each product.

When testing a foliar application:

• Apply during a cool, low-light period.
• Test a small section of foliage first.
• Avoid direct sunlight and intense grow lights while leaves are wet.
• Use an appropriate wetting agent only at its recommended rate.
• Avoid spraying damaged, wilted, or heat-stressed plants.
• Do not spray developing flowers or harvestable plant portions unless the product label specifically permits it.

Measuring Concentrated Powders

Many RAW products are used at fractions of a teaspoon per gallon. Accurate measurement is important because small volume errors can significantly change the concentration.

For greater consistency:

• Use dedicated measuring spoons for fertilizers.
• Consider a precision gram scale when gram-based directions are available.
• Keep measuring tools clean and dry.
• Never return unused measured powder to the original pouch.
• Record the amount used in each recipe.
• Seal every package immediately after measuring.

Important Usage Notes

• Do not mix all twelve products together simply because they are included in the kit.
• Use each product according to its individual directions.
• This variety pack does not automatically replace a complete base fertilizer.
• Diagnose pH, EC, irrigation, and root-health problems before treating an assumed deficiency.
• Begin with conservative rates when introducing a new product.
• Monitor total nutrient strength after adding mineral fertilizers.
• Some products may change reservoir color, foam, or biological activity.
• Store every pouch tightly sealed in a cool, dry location.
• Protect water-soluble powders from humidity and moisture.
• Keep products in their original labeled packages to prevent mixing errors.
