Impact Bloom A+B is the definitive tool for the grower who refuses to choose between the explosive yield of mineral nutrients and the quality of biological crops. This 2-part flowering fertilizer has been formulated to supply every essential macro and micronutrient your plants need to generate dense, heavy, and resin-packed flowers, ensuring a hassle-free feeding routine.
Are you tired of dealing with thick, muddy fertilizers that end up clogging your irrigation pipes just when your plants need food the most? It is a common nightmare: you want to push your crop to the limit, but the nutrient density creates blockages, pH fluctuations, and uneven feeding.
The consequences are frustrating. You spend more time cleaning drippers and worrying about salt buildup than enjoying the process. A clogged system means thirsty plants, stress, and a direct hit to your final gram-per-watt ratio. Maintaining the status quo with outdated formulas is simply costing you yield and peace of mind.
The solution is Impact Bloom A+B. Grotek has developed a highly refined bio-mineral formula that flows like water but feeds like a beast. By separating the components into two parts, it prevents nutrient lockout and crystallization, ensuring that every drop of Cannabis fertilizers reaches the roots instantly. It is the perfect balance for a smooth, potent, and problem-free flowering phase.
Using Impact Bloom A+B feels like putting your grow room on autopilot. From the first week of application, you will notice how the plants transition vigorously into flower production. The stems strengthen to support the weight to come, and the internodes fill with pre-flowers at a surprising speed.
Emotionally, it gives you the confidence of a pro. You know you are feeding your girls with a pharmaceutical-grade cocktail. The result is visible to the naked eye: buds that fatten day by day, maintaining a healthy green color without the typical burns of cheap mineral fertilizers. It is the peace of mind of knowing that your hydroponic system is clean and your plants are eating like queens.
To get the monster yields Grotek is famous for, you need to use this product with precision. Here are some pro tips:
Why should you switch to this 2-part system? Here is the breakdown:
Impact Bloom A+B is the foundation, but it plays very well with others. If you used Impact Grow A+B during the vegetative stage, the transition will be seamless. For those seeking record-breaking density, this base nutrient pairs perfectly with a PK booster in the final weeks.
Also, since it is pH stabilized, it works in harmony with high-end substrates and additives. It is the engine of your nutrition program, allowing supplements to do their specific job without fighting for absorption.
Absolutely. While it shines in hydro due to its solubility, it works wonders in soil and peat mixes, providing fast-acting nutrients that organic soil amendments sometimes lack.
The general rule is between 1 and 2 ml per liter of water for each part (A and B). However, always check your plant's reaction and the EC level, especially in recirculating systems.
Some essential nutrients, like Calcium and Phosphorus, can react and precipitate (turn into solids) if stored together in high concentrations. Keeping them separate until dilution ensures your plant gets everything.
I remember testing the Impact line on a hydroponic crop of Northern Lights a while back. Usually, around week 4 or 5 of flowering, I have to dismantle the drippers because the salts from other fertilizers create a crust that blocks the flow. With Impact Bloom A+B, the lines remained pristine until the day of the chop.
But the best part was the density. The buds were rock hard, not that airy fluff you sometimes get with poorly balanced hydro nutrients. If you want a "set it and forget it" reliability with top-shelf results, this duo is a safe bet in my book.

Can you tell me if the 4L formula is really 2L each? Or is it really 4L for each container, A + B, so 8L in total? I don't understand. I would like to buy the 4L formula, but I am not sure about the volume per container. Knowing this would allow me to quickly purchase this item because the solo-tek bloom hardens way too fast!!!! This looks perfect. Thank you for informing me, dear friends :)
