Advanced Nutrients Sensi Bloom A+B Pro, Water-Soluble Powder – Professional Bloom Booster for Maximum Yield & Potency

Advanced Nutrients Sensi Bloom A+B Pro is the definitive two-part water-soluble powder engineered to unlock the explosive flowering potential locked within your genetics. This isn't just another bloom booster; it's a precision tool backed by over two decades of dedicated cannabis research, designed to 'Hit the Shift'—the critical change in nutrient ratios your plants crave during bloom to produce their heaviest, most resinous yields.

Ever feel like your plants are holding back in flower, no matter what you feed them? You pour your heart, time, and money into a grow, only to be rewarded with fluffy, underwhelming buds that lack the density and punch you know your genetics can deliver. It's frustrating, wastes resources, and leaves you wondering if you'll ever hit those legendary gram-per-watt numbers or trophy-worthy trichome coverage you see online. That disappointment isn't a reflection of your skills; it's a sign your nutrients aren't speaking your plant's language during its most critical phase.

The agony of a subpar bloom phase goes beyond just small yields. It means wasted electricity, underutilized space, and a harvest that doesn't justify the effort. You're left with bud that's harder to trim, less impressive to share, and ultimately, less valuable. You know your setup is capable of more, but without the right nutritional key, that genetic vault stays locked. Settling for generic bloom feeds is like trying to win a Formula 1 race with regular gasoline—you'll finish, but you'll never see the podium.

The solution is hitting 'The Shift.' Advanced Nutrients spent years mapping the exact macro, secondary, and micronutrient ratios cannabis devours during bloom versus grow. Sensi Bloom A+B Pro is the result: a powder that delivers more nitrogen, potassium, and zinc while carefully reducing calcium, iron, and boron to match your plant's changed appetite. This precise balance prevents toxicities, maximizes absorption, and creates the ideal acidic root zone environment cannabis loves. It's the difference between feeding your plants and fueling their destiny.

What Real Value Does This Powder Bring to Your Harvest?

This isn't about adding bulk; it's about building quality and potency from the inside out. By providing the exact nutrients in the right proportions, Sensi Bloom A+B Pro helps your plants channel all their energy into bud development. You'll notice tighter node spacing, faster flower set, and a rapid accumulation of resin that translates directly to weight and bag appeal. The value is in every dense, frosty cola that fills your jars and justifies every watt of light you've burned.

Think of it as an investment that pays back at harvest. The increased yield and enhanced potency mean you get more usable, high-value flower from the same space and time. It turns your bloom room from a cost center into a profit engine, ensuring you're not just growing weed, but growing an asset.

Format, Lifespan, and Mixing Efficiency

Sensi Bloom Pro comes as a two-part, water-soluble powder (Part A and Part B), packaged for professional and serious home growers. Its dry format offers superior shelf life and concentration compared to liquid nutrients, meaning it stores easily and goes a long way.

• Format: Dry, highly soluble powder. Part A and Part B are kept separate to prevent nutrient lockout and ensure stability until mixing.
• Maximizing Efficiency: Always mix Part A separately into your reservoir water first, stir until fully dissolved, then add Part B. This prevents precipitation and ensures every gram dissolves cleanly for a uniform feed.
• What Affects Lifespan: Stored in a cool, dry place away from direct sunlight, the powder itself lasts for years. In solution, use within a week for optimal potency. The lifespan of its benefits in your plants depends on consistent application throughout the entire bloom phase.
• Avoiding Waste: Use a precise digital scale to measure grams per gallon/liter. Pre-mixing stock solutions for automated dosing systems (like Dosatron) is recommended for large-scale ops to ensure consistency and save time.

Advantages and Benefits: Why This Beats Generic Bloom Feeds

• Precision 'Shift' Formula: Unlike all-in-one or three-part systems, the separate A+B powders allow for the precise calcium and iron reduction your plants need in bloom, preventing toxicity and freeing up potassium uptake for bigger buds.
• Triple-Chelated Iron: Features EDTA, EDDHA, and DTPA chelates for maximum iron absorption across a wider pH range (5.5-6.3), ensuring your plants never miss this critical element for photosynthesis and metabolism.
• Cation-Rich & Urea-Infused: The formula is rich in cations like urea, which naturally acidifies the root zone. This creates the perfect, slightly acidic environment cannabis roots thrive in, promoting larger root masses (and bigger yields) without constant pH adjustment struggles.
• Standardized & Concentrated: 9.7% more concentrated than many competitors, and standardized so you use equal amounts of Part A and Part B. This simplifies mixing, reduces errors, and provides more value per gram.
• Designed for Commercial Workflows: Fully soluble for trouble-free use in drip irrigation, NFT, flood and drain, aeroponics, and other continuous feed systems. No clogs, no settling.
• Pure Inputs: Sourced from high-purity suppliers, not cheap ag-grade salts, ensuring no heavy metal contaminants that can slow growth or taint your final product.
• Unlocks Genetic Potential: By satisfying the specific bloom-phase hunger, it allows your plants to express their maximum THC/CBD potential and terpene profile, leading to more powerful aroma, flavor, and effect.

Tricks to Maximize Your Results Without Overspending

Start with a slightly lower dose (e.g., 2.5 g/gal) for the first week of bloom to let plants transition smoothly. Always monitor EC/PPM—Sensi Bloom is potent, and more isn't always better. Pair it with a quality carbohydrate supplement like CarboBloom during weeks 3-6 of flower to feed the beneficial microbes and fuel resin production. For growers in coco coir, consider supplementing with Sensi Cal-Mag Xtra if you see any early signs of deficiency, as coco can bind certain nutrients.

Most importantly, don't stop at week 6 or 7. Many strains benefit from feeding right up until the final flush. Follow the official Advanced Nutrients feed chart, but let your plants' appearance guide you—dark green leaves and praying tops mean you're dialed in.

Frequently Asked Questions

Can I use Sensi Bloom Pro in soil?

Yes, absolutely. While optimized for hydroponic and continuous feed systems, it works excellently in soil when mixed into your watering solution. Just be sure to adjust your pH after mixing, as with any nutrient.

Do I need to use both Part A and Part B every feeding?

Yes. The system is designed as a two-part base nutrient. Using only one part will create severe nutrient imbalances and deficiencies. Always use them together in equal measure as directed.

How does this compare to the liquid Sensi Bloom?

The water-soluble powder (Pro Series) is more concentrated, has a longer shelf life, and is specifically engineered with 'The Shift' in mind based on newer research. It's the professional-grade evolution of the trusted liquid line.

Is it compatible with other Advanced Nutrients additives?

Perfectly. You can and should stack it with bloom boosters like Big Bud Powder, bud hardeners like Rhino Skin, and finishers like Overdrive to create a complete, synergistic feeding program.

How long does a bag last?

This depends entirely on the size of your garden and feeding strength. For a single 1kg bag, a small home grower running a few plants can expect it to last multiple cycles. Large commercial growers will calculate based on their reservoir size and feed frequency.

Personal Experience of Pevgrow’s CEO (Alan)

Let's be real, when you're running a commercial op or even a serious home setup, you stop seeing nutrients as bottles and start seeing them as ROI. That's the lens I use. I've tested countless bloom bases, and many are just re-branded tomato feed. Sensi Bloom Pro is different. You see it in the stem thickness by week 3 of flower and the way the buds stack density instead of just stretching. I run it in my RDWC systems, and the solubility is flawless—no gunk in the lines, no precipitate in the reservoir. The 'Shift' science isn't marketing fluff; you can literally watch the plant's nutrient demands change, and this powder changes with it. My tip? Don't cheap out and try to run it at half strength to save money. Use it as directed for at least one cycle. The yield increase alone will pay for the bag, and the quality jump—the tighter structure, the heavier trichome blanket—is what turns good weed into great weed. For me, it's a non-negotiable part of the recipe for top-shelf flowers.
