Aptus Super PK – Premium PK Bloom Booster for Explosive Flowering & Denser Buds

The Aptus Super PK is your secret weapon for the flowering stage, a scientifically formulated bloom stimulator designed to push your plants into overdrive and deliver harvests that are not just bigger, but significantly better in quality and potency.

Stuck with fluffy buds and underwhelming yields?

You've nurtured your plants through veg, watching them grow strong and healthy. But when flowering hits, the results just don't match the effort. The buds are airy, the trichome coverage is sparse, and the final weight leaves you wanting more. It's frustrating to invest time and energy only to get a harvest that doesn't reflect your plant's true genetic potential.

This is where most growers hit a ceiling.

Without the right nutritional triggers at the precise moment, your plants simply won't produce the dense, resinous buds you're aiming for. You end up with a garden full of promise but a harvest jar that's half-empty. It feels like you're missing out on the explosive flowering phase that turns good grows into legendary ones.

The Aptus Super PK is the high-octane fuel your flowering phase has been craving.

This isn't just another PK booster; it's a precision tool. By delivering a powerful, balanced dose of phosphorus (20%) and potassium (23%) alongside readily available L-amino acids, it sends a clear signal to your plants: it's time to build massive, rock-hard flowers. It transforms potential into palpable, sticky results.

Why this product is a game-changer for your harvest

Forget generic supplements. Super PK works on a cellular level to optimize the flowering process. While basic nutrients keep your plants alive, Super PK actively directs energy and resources into bud formation and resin production. You'll notice the difference in the structure, weight, and sparkle of your flowers from the very first application. It's the upgrade that bridges the gap between a decent harvest and a truly exceptional one.

Key features you'll notice from week 3 of flower

• High-Concentration PK Formula (20% P / 23% K): Provides the exact macro-nutrients needed for explosive bud development and sugar production, leading to visibly denser and heavier colas.
• Enhanced with L-Amino Acids: These organic compounds improve nutrient uptake and assimilation, ensuring your plants can actually use the powerful PK boost you're giving them.
• Fully Water-Soluble & pH-Stable: Integrates seamlessly into any feeding regimen, whether you're in soil, coco, or a full hydroponic system like a DWC or NFT setup. No clogs, no drama.
• Boosts Bud Firmness & Structure: Promotes stronger cell walls in the flowers, resulting in compact, market-ready buds that are a joy to trim and cure.
• Stimulates Resin & Terpene Production: The optimized nutrition supports the plant's natural processes for creating trichomes and terpenes, enhancing both potency and aroma.
• Cost-Effective Due to High Concentration: A little goes a very long way. With a dosage of just 2.5-5ml per 10 liters, one bottle services multiple cycles, making it a smart investment for your garden.

Who this product is especially interesting for

Super PK is the missing piece for growers who are done with average results. It's particularly valuable for:

• Growers chasing maximum yield and density: If you want every gram your genetics can offer, this is your tool.
• Connoisseurs focused on quality: For those who prioritize resin content, terpene profile, and bag appeal over sheer volume alone.
• Hydroponic and coco growers: Its perfect solubility makes it ideal for precise, controlled environments where every input counts.
• Growers using other premium base nutrients: It's designed to complement and supercharge any quality feeding program, not replace it.

How to integrate it into your routine without overcomplicating things

Using Super PK is refreshingly straightforward. Simply add it to your nutrient solution from the 3rd or 4th week of flowering onwards. Start with the lower dose (2.5ml/10L) to see how your plants react, especially if they are sensitive strains. You'll use it every feeding until the final flush. It mixes instantly, and because it's so concentrated, you'll see the bottle last through several grows. Pair it with a good pH meter to monitor your solution, as its alkaline nature can raise pH slightly—an easy adjustment that's part of any pro grower's routine.

Frequently Asked Questions

When should I start using Aptus Super PK?

Begin applications at the onset of true flowering, typically around week 3 or 4 after switching to 12/12. For more sensitive strains, waiting until week 4-5 is recommended to avoid any potential nutrient stress.

Can I use it in organic soil grows?

Absolutely. While it's an organo-mineral product, its components are readily available for plant uptake. It works brilliantly in living soil or any organic substrate to give your flowers a final, powerful push.

How does it compare to other PK boosters?

Super PK stands out due to its very high concentration (20/23) and the inclusion of L-amino acids. This makes it more potent and efficient per ml than many common 13/14 formulas. You use less product to achieve a greater effect.

Do I need to adjust my pH when using it?

Yes. Super PK has a high pH (around 8.5-9). Always check and adjust the pH of your final nutrient solution after adding it. Aim for your medium's ideal range (5.5-6.5 for hydro/coco, 6.0-6.8 for soil).

Is it suitable for all growing mediums?

Yes, it is fully water-soluble and designed for use in soil, coco coir, and all types of hydroponic and aeroponic systems.

Personal Experience of Pevgrow’s CEO (Alan)

I've tried a lot of bloom boosters over the years, from the simple to the wildly overpriced. What brings me back to Aptus Super PK is its raw efficiency and the tangible results I see in the garden. Before using it, I'd sometimes get flowers that looked great but felt a bit light in the jar. Super PK changed that. It's like it tells the plant to redirect all its energy into building the bud structure itself. The colas get noticeably heavier and more compact, and the resin production seems to kick into a higher gear. I particularly like using it in my coco grows alongside a solid base nutrient; the plants just eat it up. My tip? Don't be heavy-handed. Start with the lower recommended dose and watch how your specific strains respond. Some of the densest, most photogenic buds I've ever harvested have had Super PK in their diet from the mid-flower point onward. It's a staple on my shelf for a reason.
