Canna PK 13/14 0.5l
Canna PK 13/14 0.5L is the mid-range format of Canna's best-selling bloom booster — a concentrated pure phosphorus-potassium blend (NPK 0-13-14). At 1.5 ml per litre, this bottle yields approximately 333 litres of solution, covering many bloom cycles across multiple seasons. The proprietary production process combines P and K at high concentrations for direct absorption. Phosphorus stimulates cell formation, potassium regulates sugar production and water transport. Apply for approximately one week during peak bloom alongside your regular base nutrition. Compatible with all substrates. The balanced format for regular growers who maximise bloom performance every cycle. Fast delivery across Belgium for consistent growers.
Canna PK 13/14 0.5L – The Proven Bloom Booster for Regular Growers
Experienced growers know that a precisely timed bloom boost separates a good harvest from an exceptional one. Canna PK 13/14 0.5L delivers that critical intervention every cycle, with 333 litres of solution from a single bottle — enough for multiple seasons. This concentrated phosphorus-potassium blend (NPK 0-13-14) has been the benchmark bloom booster in the Canna range for decades.
Why timing is everything with PK 13/14
Unlike products used continuously, PK 13/14 is a single targeted intervention at the critical moment. Around weeks 5–7 of bloom — approximately 3 weeks before harvest — phosphorus and potassium demand peaks dramatically. At that precise moment, you add PK 13/14 to your regular bloom nutrition for approximately one week. The high concentration and immediate solubility ensure the plant can absorb everything instantly and convert it directly into flower mass and sugar production.
What PK 13/14 delivers to your plants
- Larger, heavier flowers: supplementary phosphorus strengthens cell formation in flowers and fruits for more volume and weight.
- Sweeter flavour and intensified aromas: potassium drives sugar production and increases BRIX levels in fruits.
- Stronger plant structure: potassium improves water transport and stem/branch rigidity to support heavy bloom weight.
- Immediate uptake: proprietary production process makes P and K instantly available with zero harmful residue.
Professional application tips
Always add PK 13/14 first to water, mix thoroughly, then top up with base nutrition to target EC. Combine with Canna Boost Accelerator 0.5L for the most potent bloom combination. Start each cycle with Rhizotonic for optimal rooting, and maintain root zone health with CannaZym throughout.

Should I stop base nutrition when using PK 13/14?
No — PK 13/14 is an additive that supplements your regular bloom nutrition. Add PK 13/14 first, mix well, then top up with your base feed. You may need to reduce base nutrient concentration slightly to avoid overfeeding.
Is PK 13/14 compatible with soil and coco?
PK 13/14 is compatible with all substrates: soil, coco and hydroponics. It works in recirculating systems, drain-to-waste setups, and is suitable for both indoor and outdoor cultivation.
How many litres of solution does the 0.5L bottle produce?
At 1.5 ml per litre, the 0.5L bottle yields approximately 333 litres of solution. Since PK 13/14 is applied for only about one week per cycle, this covers many seasons for an average-sized setup.
How long should PK 13/14 be used per bloom cycle?
Apply PK 13/14 for approximately one week during peak bloom. For 8-week flowering plants, apply around week 5. For longer cycles (12 weeks), extend to up to 2 weeks. It is a brief but powerful intervention at the optimal moment.
