The B.A.C Organic PK Booster is your secret weapon for the flowering stage, a concentrated, natural formula designed to supercharge bud development, amplify terpene profiles, and push your yields to their absolute peak.
Ever feel like your buds just aren't reaching their full potential? You feed them, you love them, but come harvest, the flowers are a bit airy, the flavors muted, and the yield just doesn't match the effort you put in. That's the frustrating gap between a good grow and a legendary one. It's not just about weight; it's about the quality, the bag appeal, and that mouth-watering flavor that makes all your patience worthwhile.
When your plants switch to flowering, their nutritional needs shift dramatically. They're no longer building stems and leaves; they're putting all their energy into creating dense, resinous buds. This process demands a massive amount of phosphorus (P) for energy transfer and flower formation, and potassium (K) for regulating water, strengthening cell walls, and boosting sugar and terpene production. Skimping here is like trying to run a marathon on an empty stomach – you'll finish, but you won't break any records.
Using a generic base nutrient alone often leaves this crucial demand unmet. The result? Lanky, loose buds that lack density, underwhelming trichome production, and flavors that don't pop. You end up with a harvest that's just "okay," when it could have been "incredible." That's wasted time, energy, and love for your plants.
This is where the B.A.C Organic PK Booster steps in as the perfect, targeted solution. It's like giving your plants a precision-engineered fuel injection right when they need it most. Formulated specifically for the flowering phase, it delivers bioavailable phosphorus and potassium in perfect harmony with your organic grow, ensuring your plants have everything they need to build rock-hard, aromatic, and incredibly flavorful buds.
While a good base nutrient is essential, adding the B.A.C Organic PK Booster is what separates a hobbyist harvest from a connoisseur-grade crop. Here's why it's a game-changer:
Forget complicated science; here's what this booster actually does for you and your garden. You'll see buds that are noticeably denser and heavier, packing more weight into the same space. The aroma during the late flowering stage will become intensely complex and specific to your strain's genetics. When you finally taste your cured harvest, the flavors will be richer, smoother, and more pronounced. Your plants will also show improved overall health and resilience during the demanding final weeks. Ultimately, you'll harvest more of the top-shelf quality bud you're aiming for, making every gram count.
Yes, it is generally compatible with other organic or mild mineral base nutrients. However, for optimal results and to avoid nutrient lockout, it's best used within the complete B.A.C nutrient line. Always start with a lower dose when mixing brands.
Absolutely. The inclusion of Yucca extract makes it particularly effective in both soil and coco coir mediums, aiding in even nutrient distribution and stable water management.
This depends on your garden size and dosage. For a single plant in a medium-sized pot, using 2-3 ml per liter, a 1L bottle can easily last multiple full flowering cycles. For larger indoor setups, the 5L size offers much better value.
As an organic product, it is generally pH-stable and designed to work within a wide range. However, it's always good practice to check and adjust the pH of your final mixed solution before feeding your plants.
We recommend stopping all nutrient feeding, including the PK Booster, 1-2 weeks before your planned harvest date. This allows the plant to use up residual nutrients, leading to a cleaner, better-tasting final product.
I've been through the cycle of trying every booster under the sun, and many of them promise the world but deliver very little, or worse, they burn your plants with harsh salts. The B.A.C Organic PK Booster was a breath of fresh air. I first used it on a run of a classic Kush strain that I knew could be a bit leafy. The difference was undeniable. The buds swelled up noticeably denser, and the classic earthy-pine scent transformed into something much richer and more complex. The sugar leaves were absolutely caked in trichomes by week 7.
My preferred method is to introduce it slowly. I start with just 1 ml/L when the first pistils show, bump it to 2 ml/L during the bulk of flowering, and sometimes push to 3 ml/L for a week or two if the plants are looking hungry and strong. I always use it alongside their base Bloom feed. Compared to other boosters, I find it's much gentler on the plants—no sudden leaf curl or tip burn—but the results are anything but gentle. You get that explosive flowering push without the stress. For any grower committed to organic methods but who still wants professional-level density and flavor, this is a non-negotiable in my feed schedule. It's the difference between a good homegrown and a batch that makes your friends ask, "Wait, you grew this?"
