Pure Horticultural Science.

There are boosters, and then there’s Canna PK 13/14 — a phosphorus-potassium cocktail so concentrated and efficient, it might as well come with its own warning label and a pair of sunglasses. This isn’t some whimsical plant tonic brewed up by someone who once read a gardening blog. This is pure horticultural science, weaponised and bottled by the experts at Canna, a name that’s spoken in growing circles with the same hushed reverence usually reserved for rockstars or rare whisky.

Bigger, Heavier Flowers.

Let’s get straight to the clever bit. Canna PK 13/14 is a highly refined blend of phosphorus (P) and potassium (K) — two macronutrients that, when applied at just the right moment, trigger plants into going absolutely berserk during their generative phase. Phosphorus, that enigmatic little element, strengthens flower cell formation and is a key player in energy transfer. In simple terms, it’s the battery pack for blooming. When your plants start needing more energy than your smart meter during a January cold snap, phosphorus is what keeps the lights on.

Better Tasting Fruits.

Then we’ve got potassium. Now potassium is the logistics manager of your plant. It’s not just floating around being helpful; it’s running water, nutrients and sugar around like a well-oiled delivery service. It controls processes that are so critical to plant quality and structure, it might as well be wearing a high-vis jacket and yelling into a walkie-talkie. Potassium is what ensures those flowers aren’t just big, but also properly developed and structurally sound — not just inflated nonsense.

Increased Yields.

Here’s where Canna PK 13/14 shows off. Thanks to Canna’s meticulously engineered production process, the purity of this formula is ridiculous. It’s so refined and bioavailable that it doesn’t hang around faffing about in the substrate. It hits the plant’s metabolism directly and quickly. Which is exactly what you want in those crucial final weeks of flowering when the plant’s nutrient demands skyrocket and timing is everything.

Suitable For Every Medium.

And don’t think this is a diva of a product that only works in specific conditions. Canna PK 13/14 works across the board — soil, coco, hydroponics, indoors, outdoors, run-to-waste systems, and even those tight little stealth cupboards that have about as much ventilation as a Victorian mine shaft. It’s particularly brilliant for anyone using LED grow lights, where nutrient uptake can be more precise and efficient, meaning the plant can process this formula with surgical precision.

Now, combine this with Canna Boost and you’ve got the floral equivalent of a jet engine strapped to a skateboard. The synergy between these two is staggering. Boost revs up the metabolism while PK 13/14 delivers the knockout nutrients. Flowers become denser, heavier, and frankly, a bit absurd in size.

Available In 3 Sizes.

Available in three sizes, so whether you’re pottering about with a single specimen or managing an industrial fruiting setup, there’s a bottle that fits your needs. And because you only need to use it once a week, it ends up being tremendous value for money. One dose and your plants know it’s time to get serious.

Canna PK 13/14 isn’t optional. It’s essential. It’s the final push your plants need to turn from promising to phenomenal. Bravo, Canna. You’ve done it again.
