The Bio Nova PK 13-14 Bloom Stimulator is the legendary, original PK booster, engineered to supercharge your flowering phase and deliver the explosive bud development you've been dreaming of.
You've put in the weeks of veg, dialed in your environment, and your plants are finally in flower. But instead of dense, heavy colas, you're watching fluffy, airy buds form. It's frustrating, right? You know your plants have more potential, but something's missing in that critical flowering push.
Without the right phosphorus and potassium at the right time, your plants simply can't build the dense, resin-packed structures that make for a legendary harvest. You end up with more leaf than flower, a weak aroma, and a final yield that doesn't justify all your effort and care. It feels like you're leaving grams—or even ounces—on the table every single cycle.
This isn't just another additive; it's the formula that defined the category. Bio Nova pioneered the perfect 13-14 Phosphorus-Potassium balance to act as a metabolic trigger during bloom. It provides the pure, food-grade minerals your plants need to redirect all their energy into creating thicker, heavier, and more aromatic buds. Think of it as the final gear in your grow's transmission, unlocking the top-end power for a finish that blows the doors off.
While many bloom boosters promise the world, PK 13-14 delivers a specific, science-backed result: optimized flower development. Its value lies in its simplicity and purity. It contains barely any ballast salts or heavy metals, meaning your plants can absorb the nutrients immediately and nothing unwanted remains in your final product. For the cost of a few grams of extra yield, this bottle pays for itself many times over, turning a good grow into a great one. It's the essential tool for any grower who measures success by the weight and quality of their jar.
Let's tackle the common doubts head-on.
To get the legendary results, follow these simple steps.
Yes, absolutely. While it is a mineral-based product, its high purity and immediate availability make it an excellent supplement to boost flowering in organic soil systems. It won't harm your microbial life when used at recommended doses.
Cease use about 7-10 days before your planned harvest. This gives the plant time to use up the remaining nutrients and is part of a proper flushing process for the cleanest final product.
Bloom base nutrients provide a full spectrum of elements for the flowering stage. PK 13-14 is a targeted supplement that provides a supercharged dose of just Phosphorus and Potassium. Think of your bloom nutrient as the main course and PK 13-14 as the powerful, flavor-enhancing spice.
Yes, it mixes seamlessly with other additives. In fact, using it alongside a carbohydrate booster can be synergistic, as the PK helps the plant utilize those sugars more effectively for bud building.
Yes, but with caution. Autoflowers have a shorter life cycle. Start with a lower dose (2ml/10L) and observe. It's best used from the first sign of pre-flower through mid-bloom, tapering off earlier than you would with photoperiod plants.
I'll be honest, I was skeptical about PK boosters for years. I thought a well-balanced A&B feed should cover everything. Then I ran a side-by-side test in one of our test tents. The difference wasn't subtle; it was dramatic. The plants treated with Bio Nova PK 13-14 developed buds that were noticeably denser and heavier to the touch. The resin production seemed to kick into a higher gear, and the final dry weight was over 15% higher on the PK side. The key for me is the purity. Because it's made from food-grade minerals, I never worry about it clogging my drip lines in hydro or leaving any harshness in the flower. My pro-tip? Don't go crazy with the dose. More is not better. Stick to 3-4ml per 10L and let it work its magic consistently through the bloom phase. It's the one bottle I won't run a flowering cycle without anymore.
