King Kola by Emerald Harvest is the definitive flowering booster designed to transform your crop into a heavy, resinous production machine, thanks to its unique hemp protein-based formula. It acts as a powerful catalyst that not only feeds your plants but structures the flowers to reach their maximum genetic potential.

Why choose King Kola for your crop?

Are you tired of harvesting airy buds that lose half their volume when dried, leaving you with a disappointing yield? It is a common frustration among growers: you have good lights and good seeds, but the final weight just isn't there.

There is nothing more painful than spending months caring for your indoor or outdoor garden only to end up with "popcorn" flowers that lack density and punch. That mediocre result wastes your time, your electricity, and your money.

King Kola solves this immediately by providing the exact PK boost and vegetable proteins your plants need to fatten up like never before. It is the professional solution to turn potential into heavy, hard reality.

Maximum density for your buds

This product isn't just another P-K additive. The magic lies in its hemp seed flour content. This vegetable protein acts as a natural chelator, helping your plants absorb nutrients much faster and more efficiently. By using King Kola, you are essentially giving your plants the perfect building blocks to create cell walls, resulting in flowers that are not only bigger but significantly denser.

Whether you are looking for the best Fertilizer for flowering or simply want to beat your personal gram-per-watt record, this booster integrates perfectly into your feeding schedule to deliver heavier harvests with a robust structure.

How to use King Kola Emerald Harvest

Getting the most out of this booster is simple, but consistency is key. It is designed to be used throughout the flowering phase.

  1. Preparation: Shake the bottle vigorously before opening. The organic proteins can settle at the bottom.
  2. Dosage: Apply between 1ml and 3ml per liter of water, depending on the week of flowering. Start with the lower dose when flowers begin to form (Early Flowering) and increase it as they fatten (Mid to Late Flowering).
  3. Application: Add it to your nutrient tank after your base nutrients but before adjusting the pH.
  4. Compatibility: You can use it in soil, coco coir, and it works exceptionally well as part of your Hydroponic Nutrients regimen.
  5. Stop: Remember to stop using it during the final flush week to ensure a clean taste.

Key advantages and benefits

  • Hemp Seed Protein: Provides natural chelation, allowing the plant to absorb Phosphorus and Potassium faster, resulting in accelerated growth.
  • High PK Content: Delivers the essential macronutrients for bloom, ensuring that every calyx swells to its maximum capacity.
  • Versatility: Works in any medium, making it a staple among our Cannabis fertilizers for both novice and expert growers.
  • Added Nitrogen: Contains a small amount of Nitrogen derived from hemp, keeping the plant healthy and green enough to support massive bud production without stalling.
  • No Dye: The formula is clean, preventing residue buildup and ensuring the purity of your final product.

Care and maintenance

To keep the proteins in King Kola active and effective, store the bottle in a cool, dark place, away from direct sunlight and extreme temperatures. Always use clean pipettes or measuring cups to avoid contaminating the bottle. Since it contains organic material, close the lid tightly after every use to prevent oxidation.

Frequently Asked Questions

Can I use King Kola with other nutrient brands?

Yes, although it is formulated to work synergistically with the Emerald Harvest line, its high-quality PK and protein profile make it an excellent booster to combine with almost any base nutrient.

Does it affect the pH of my water?

Like most concentrated nutrients, it can slightly alter the pH. Always add King Kola to your water, mix well, and then measure and adjust the pH to the optimal range (5.8–6.3 usually) before watering.

Is it suitable for autoflowering plants?

Absolutely. For autos, we recommend starting with half the recommended dosage to see how the plants react, as they can be more sensitive to high nutrient levels.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested dozens of bloom boosters over the years, and many are just simple PK formulas. What surprised me about King Kola is the hemp protein aspect. You can actually see the difference in the resin production; the buds don't just get heavy, they get sticky. It feels like the plant recognizes the hemp-derived nutrients more naturally.

My personal trick is to push the dosage slightly in weeks 4 and 5 of flowering (for an 8-week strain). That's when the calyxes are really exploding, and King Kola provides that extra fuel to turn them into rock-hard nuggets. If you want bag appeal and weight, this is a bottle you need on your shelf.
