Berkana is the high-concentration biomineral supplement designed to transform your crop's potential into tangible weight. It is a soluble powder fertilizer with a potent NPK 10-30-20 ratio, enriched with marine salts, humic compounds, and amino acids, specifically formulated to trigger explosive flowering and guarantee dense, resinous buds.

Does it happen to you that, even using the same setup, your harvests are inconsistent from one cycle to the next? It is incredibly frustrating to put in months of work and electricity only to find that the buds didn't fatten as much as the last time, leaving you wondering if it was the temperature, the genetics, or the food.

This lack of consistency not only hits your wallet but also undermines your confidence as a grower. You spend hours trying to "guess" the perfect mix, dealing with dozens of liquid bottles that degrade over time, creating a margin of error that prevents you from reaching that professional standard you are looking for.

Berkana is the solution to eliminate that uncertainty. By providing a stable, highly concentrated, and easy-to-dose formula, it acts as a precision tool that ensures your plants receive exactly the Phosphorus and Potassium they need to fatten up, along with the organic vitality of amino acids, guaranteeing repeatable and superior results in every harvest.

Why Berkana helps you get more consistent results

The magic of Berkana lies in its hybrid composition. On one hand, you have the precision of mineral salts (NPK 10-30-20) that give you immediate control over the plant's nutrition, ensuring that there is never a lack of energy for flower formation. On the other hand, the inclusion of natural extracts, fruit oils, and fatty acids creates a buffer effect that improves soil life and nutrient absorption.

Being a powder format, Berkana remains stable for much longer than liquid fertilizers. This means that the dose you apply today has the same potency as the one you will apply in three months. You eliminate the variable of "expired nutrients" from the equation, allowing you to repeat your success cycle after cycle with mathematical precision.

Factors that influence the result and how to control them better

  • Nutrient Concentration: With a 10-30-20 ratio, you are directly targeting the fattening phase. You control exactly how much PK your plants get without guessing.
  • Solubility and Versatility: It is perfectly soluble, making it ideal for Hydroponic and Aeroponic Systems, as well as soil and coco.
  • Stress Resistance: The added amino acids help the plant recover from environmental stress (heat, pruning), ensuring that external factors don't ruin your final weight.
  • Substrate Health: Unlike purely chemical fertilizers, humic compounds improve the structure of your Soil For Cannabis, facilitating root uptake.
  • Dosage Precision: 100g for 100 Liters (1g/L) is a simple, round metric that reduces measuring errors.
  • Trace Elements: Includes Magnesium (2%) and micronutrients to prevent silent deficiencies that limit yield.

Recommended routine to achieve good results every time

  1. Prepare: Fill your tank with water and let it sit if you need to dechlorinate.
  2. Dissolve: Add 1g of Berkana per liter of water. Stir well until dissolved.
  3. Check: Measure the pH and EC. Being a concentrated powder, it will raise the EC significantly, so adjust if necessary based on your plant's stage.
  4. Water: Apply the mixture to your plants. If you use drip irrigation, don't worry, it won't clog the drippers.
  5. Observe: Watch how the flowers react. If you see burnt tips, lower the dose slightly; if they ask for more, you can maintain it.
  6. Record: Write down the exact week you started using it to replicate the "fattening boom" in the next crop.

Advantages and benefits of that consistency

  • Professional Confidence: Knowing that your nutrient mix is rock solid allows you to focus on other variables like climate or pruning.
  • Economic Savings: Being a powder concentrate (250g = 250L), you stop paying for water and plastic bottles.
  • Maximum Density: The high PK content translates directly into harder, heavier flowers.
  • Simplicity: You reduce the number of bottles on your shelf. One product covers the heavy lifting of nutrition.
  • Peace of Mind: You know you are feeding your plants with Cannabis fertilizers that combine the best of organic and mineral worlds.

Frequently Asked Questions

Can I use Berkana in hydroponics?

Yes, absolutely. The elements are water-soluble. Although you might see a tiny bit of natural sediment at the bottom of the tank due to the organic extracts, this does not clog irrigation systems or drippers.

When should I start using Berkana?

Due to its high Phosphorus (30%) and Potassium (20%) content, Berkana shines during the flowering phase. It is the perfect booster to start when the first button flowers appear until the final flush.

Is it compatible with other additives?

Yes, but be careful with the EC. Berkana is powerful. If you mix it with other PK boosters, you could over-fertilize. It works great on its own or as a supplement to a light base.

Personal Experience of Pevgrow’s CEO (Alan)

I've always been a fan of powder fertilizers for one simple reason: stability. With liquids, I sometimes felt that the bottom of the bottle was stronger than the top, or that they lost effectiveness if I left them open too long. With Berkana, I found that "sweet spot" of reliability. I open the jar, weigh my gram, and I know exactly what my girls are eating.

In my tests, what surprised me most was the density. I used it on a crop of hybrids that usually came out a bit fluffy, and the difference was palpable—literally hard as rocks. The 10-30-20 ratio is a classic for a reason; it's like a hammer for flower production.

One tip: don't be scared if you see a little residue at the bottom of the bucket. That's the organic part (the humic extracts and fruit oils) that doesn't dissolve instantly like synthetic salt, but it's pure gold for the roots. It's become a staple in my rotation when I want to ensure weight without complicating my life with ten different bottles.
