Brutal Kalium K30 by Cannotecnia is the definitive tool for growers who refuse to settle for average yields and want to squeeze every last gram out of their crop. This high-performance additive is specifically formulated to provide that extra shot of energy and minerals your plants need in the final stretch, transforming decent flowers into heavy, resin-dripping buds.
We've all been there: you spend months pampering your plants, controlling the climate, and adjusting the pH, only to reach harvest time with flowers that look big but feel airy and light. It's the classic "fluffy bud" syndrome that disappoints so many growers when they put their crop on the scale.
There is nothing more frustrating than seeing your hard work shrink to half its size during the drying process. That lack of density not only affects the final weight but also the quality of the smoke and the bag appeal. If you don't provide the specific macronutrients needed for cell compaction at the exact moment, the plant simply cannot fill those flowers, no matter how much light you give it.
The solution is to introduce a specific shock treatment like Brutal Kalium K30. By providing a massive and assimilable source of Potassium combined with Calcium and organic agents, you force the plant to close the flowers, fill the internal gaps, and generate rock-hard density. It's the difference between a bag full of air and a bag full of rocks.
Once you start adding this booster to your nutrient mix, the changes in the grow room are visible within days. The main change you'll notice is the hardness of the calyxes; the flowers stop growing vertically and start swelling from the inside out. This is essential for anyone looking for maximum profitability.
In addition, thanks to its contribution of organic carbon, the plant maintains a high metabolic rate until the end. This means that, even if you are pushing the plants to the limit to get more weight, they remain healthy and capable of assimilating nutrients. It is the perfect complement to your base cannabis fertilizers to close the cycle with a flourish.
This product isn't just "more potassium"; it's a balanced formula designed to work efficiently without blocking your substrate.
To get the most out of it without over-fertilizing, follow these simple steps during the fattening phase:
Yes, but be careful. Since it has a very high concentration of Potassium, if you mix it with another strong PK (like a PK 13/14), you could burn the plants. It is best to use Brutal Kalium K30 as your main source of fattening or reduce the doses of other additives.
Absolutely. Its formula is completely soluble and works perfectly in inert substrates like coco, rockwool, or pure hydroponic systems. Just make sure to monitor the EC (electroconductivity) of your tank.
No, as long as you respect the root flushing period. In fact, by helping the plant metabolize better and finish its cycle correctly, it can help express the terpene profile more clearly.
Calcium is vital for the transport of other nutrients and for the structure of the flower. Many fatteners forget it, but Cannotecnia includes it to ensure that the weight gain does not cause rot or weak stems.
I've tried a lot of "miracle" fatteners over the years, and many are just sugar water or unbalanced salts that end up blocking the roots. What surprised me about Brutal Kalium K30 is how quickly the plants react. In a test with an Amnesia hybrid, the difference in hardness between the plants treated with this product and those that weren't was obvious just by squeezing the buds.
My trick? I use it at the maximum dose (3ml/5L) specifically in weeks 5 and 6 of flowering (for 9-week strains), and then I lower it drastically. That peak of Potassium causes an explosion in the calyxes that is scary. If you want buds that sound like stones when they fall into the jar, this is a safe bet.
