Mega Crop 1 Part Plant food 9- 6 – 17

MEGA CROP is an all in one, complete plant nutrient designed from the ground up.  It combines the full feeding schedule and multi-product supplement lines other companies suggest into 1 easy to use product.  You get everything you need from start to finish – to grow the best quality plants.

MEGA CROP uses advanced amino-acid Chelate’s, soluble Silica, Chitosan Oligosaccharide, B-Vitamins, 18 L-Amino acids, and Kelp extract in addition to proprietary formula composition which ensures the product is soluble at up to 100x concentrations, all the while allowing the plants to have maximum absorption in a wide variety of growing conditions and growing mediums.


Which crops or plants can Mega Crop Be used on?

MEGA CROP can be used as a standalone complete feeding fertilizer and nutrient all crops or plants.  It has special forms of nutrients, and complete selection of nutrients, which allows maximum absorption for all plant types, while preventing burning or overfeeding problems, allowing it to work universally.

The formula was designed specially for fruiting and flowering plants, Tomatoes, Peppers, Strawberries, food crops and ornamentals.  The important factor is getting proper dosing strength/ppm for your crop.  Leafy green crops, which normally need higher nitrogen ratios, can be used with MEGA CROP by running higher ppm/dose than normal to supply the extra nitrogen, or by also supplementing a separate nitrogen product (such as Cal-Mag or Calcium Nitrate).

How do I store the product?

MEGA CROP storage should be done by completely sealing your bag or container after use.  Keeping air away from the powder will help it retain its powder form for as long as possible.  If you are using the 9.9kg bags, then you can seal up between use by folding the bag and using some type of clip to keep it closed.  All fertilizer products in general should be stored in cool, dry locations as much as possible.  If there is humidity or heat that is causing MEGA CROP to absorb moisture and lose form, you can also store in a bucket with sealed lid to help keep out air.

The package should be stored out of direct sunlight or heat.  Too much sunlight, heat, or exposure to air will cause the formula gain moisture and become clumpy or watery.  The formula still behaves the same, chemically it does not change, and it is designed to be water soluble.

If the product you have has clumps or hard spots, you can use normal dosage by weight or EC and dissolve in water.  Dissolving in water should take place fully from 5-30 minutes.

Is Mega Crop Organic?

The short answer is no.  At Greenleaf Nutrients, we focus on making the highest quality nutrients and fertilizers possible, which is not possible using outdated and arbitrary OMRI standards.

MEGA CROP and our fertilizer products  are Vegan fertilizers, and Organic compatible because they benefit the soil, but do not official have Organic (OMRI) certification.  Our fertilizers meet or exceed the same or higher standards as Organic fertilizers as far as toxins, heavy metals, and other contaminants and pollutants.  Our products are compatible with organic growing methods because they benefit the soil conditions and living microbes, do not contain any pesticides/toxin and do not harm the microbiology.

“Organic”  fertilizers refers to a certification done by the private company OMRI, which will give OMRI Listed® certification once paid the appropriate fees ($$) and requirements are met.  It is of our opinion the “OMRI” certification for fertilizer products is outdated and arbitrary, and doesn’t serve or convey any useful metric.  In many cases OMRI has lower or forces lower standards for ingredients, because they rely on animal products which can accumulate toxins from the environment at a high rate, and are less effective.  OMRI was created without understanding the concept of newer hydroponic growing in mind, in which nutrients and fertilizers generally are the highest possibly qualify.    For example, our Seaweed Kelp extract products are the highest quality in the industry, using low temperature enzymatic extraction, and come from the ocean as “organic molecules,” however are not considered “Organic” by OMRI because the processing facility did not pay the fees to them.

Our fertilizers have several advantages over Organic fertilizers.

Not sourced from animals, so no risk of antibiotics, antibiotic resistant bacteria, pharmaceuticals, hormones or pathogens, or heavy metal accumulation that are associated with animal based products

Far more water soluble and available to the plants, for better absorption, quicker and complete uptake by the plants, and far lower amounts required (thus requiring less shipping)

Lower environmental impact because of higher efficiency

Not supporting the animal agriculture industry which involves cruelty and some people may find not ethical

What other supplement or product types should I run with Mega Crop?

Nothing!  Since it is a true complete formula, you do not need any other products to get the best results possible.  You may want to add some pH adjuster to make sure the nutrient solution being delivered to the plants is between 5.5-6.5 pH for best absorption, this depends on your water supply and is unique to each individual farm.

Advanced growers can add in a PK booster during flowering phase, such as Bud Explosion, to ensure you are getting the maximum bloom potential.

How can you use the same formulas for both Veg and Flowering phase?

Cannabis and Hemp Veg and Flowering nutrient requirements are different, yet fairly similar.  Usually, a dedicated “veg” formula will have slightly more Nitrogen, and less Potassium, while similarly a “bloom” formula will have less Nitrogen, and more Potassium.

MEGA CROP uses a universal formula that can be used for the entire plant life, we accomplish this in a few ways.

Plants take up what they need, so during different phases of growth, the plant will search for what it needs and uptake it from the soil or nutrient solution.  As long as you are providing in sufficient quantities, the plant will have optimum growth uninterrupted.  This is the same concept that organic outdoor growers will use to get fantastic results, at the beginning of the season they do their “soil mix” which has everything that the plant will need for its whole life-cycle, from start to finish.  Through the plants life, it takes what it needs from the soil mix, and as long as everything is in sufficient quantities, it will have optimum growth.

We use extremely high quality and low Ammonium type nitrogen ingredient sources, this reduces the possibility of “overfeeding toxicity” that you would get from normal hydroponic fertilizers using too much nitrogen, even at higher doses.  So, having extra nitrogen beyond what the plant needs will not harm it.

The Feeding Schedule calls for increased dosage for different parts of the plants life.  By following the feeding schedule, the plants will always have what they need ready.  During each phase, there will be slight excess of nutrients that the plant doesn’t need as much of, however this will stay in the soil and be available in later phases.

*EC is additive, so you measure your base water EC then add in the suggested amount.
For example: Base water EC .2, suggested dosage is 1.1, then final level will be 1.1 + .2 = 1.3


EC/PPM conversion for different meter types
1 ms/cm (EC 1.0 or CF 10) = 500 ppm
European 1 ms/cm (EC 1.0 or CF 10) = 640 ppm
Australian 1 ms/cm (EC 1.0 or CF 10) = 700 ppm

1 US Teaspoon (4.9ml) = 6 grams MEGA CROP

**PK Boost option is a way for advanced growers to boost blooming performance


How to Dial In Feeding For Optimal Results

The Feeding Calculator is used as a general starting point for finding the right amount of nutrients to use.  Depending on your setup, you may benefit from using more, or less than the suggestion.  After running MEGA CROP for a few weeks you can begin to “dial-in” your feeding program, ie: modify it to achieve maximum harvest/results and have the healthiest plants!


Step 1 – Dialing In Nitrogen levels through MEGA CROP dosage by monitor your plants coloring:

  • Pay close attention to the green coloring of your plants leaves.  Nitrogen levels in MEGA CROP are strongly related to how green your plants leaves will appear
  • If your plant leaves are light green or yellow, then increase your dosage of MEGA CROP to boost Nitrogen levels and increase green color
  • If your plant leaves are too dark green and/or have burned tips, then scale back your MEGA CROP dosage to reduce the nitrogen.
  • Your goal is to have the plants coloring to be a strong healthy green without burning, and you control this by increasing or decreasing the MEGA CROP dosage.  If you are a new grower and not sure what color your plants should be at, browse the internet for pictures of healthy plants of your same type.  You should make dosage changes for the first time in small amounts, for example changes of 10-20% increase or decrease only, and then waiting 2-3 weeks to monitor plant response after each change.  Since the plant has to take time to uptake nutrients and process them, it may take 2-3 weeks to notice the results of the changes you made.

Step 2 – Dialing in your PK boost levels during bloom for maximum yields and resins:

  • Once your have achieved proper base nutrient dosage through regulating Nitrogen, then during flowering/blooming phase you can optionally add in PK booster to increase harvest.
  • PK Boosters like Bud Explosion have high amounts of P and K, and 0 (N)itrogen, so you can add them in during flowering without risking changing your plants Nitrogen levels
  • This may take some time, but you can continually increase PK boosters over several harvests to monitor for increase weight and quality.  As long as you do not notice plant damage from increasing the dosage, you can experiment by increasing the dosage, and monitoring the final end results/yields.
  • Eventually you will find the dose that maximizes your results/yields, where adding more will not give additional benefit (saturation point).
