Description
Give your flowering plants the extra push they need with CANNA PK 13/14, a high-grade bloom booster engineered to deliver a powerful dose of phosphorus and potassium when your plants need it most. Perfect for growers aiming for heavier blooms, larger fruits, richer flavours and higher yields in soil, coco or hydro setups.

CANNA PK 13/14 is a carefully formulated mineral additive, providing concentrated phosphorus (P) and potassium (K), the key macronutrients plants demand during the flowering (generative) stage. This powerful PK combination supports cell formation, sugar synthesis, water and nutrient transport and overall flower and fruit development. Because of its clean, easily absorbable formulation, PK 13/14 is fast-acting and effective across all growing media, including soil, coco, hydro and recirculating systems.
Whether you’re growing ornamentals, vegetables, or fruiting plants, using PK 13/14 at the right time can dramatically improve bloom quality and yield.
Key Features & Benefits
- Boosts Flower & Fruit Size, Density & Yield: Concentrated phosphorus and potassium stimulate flower and fruit formation, promoting larger, denser, heavier blooms and increased final yield.
- Enhances Sugar Production & Quality: Potassium supports sugar production and transport within the plant, helping improve taste, aroma and overall quality of fruits and flowers.
- Rapid Absorption & Quick Results: Fast solubility and immediate uptake allow plants to access extra nutrients quickly and efficiently.
- Compatible with All Growing Media & Systems: Works effectively in coco, soil, hydroponic systems, recirculating or run-to-waste setups.
- Works With Existing Nutrient Programs: Designed to complement CANNA base nutrients or other nutrient lines without requiring a full feed change.
- Ideal at Peak Flowering: Supplies the extra nutritional push plants need when demand for phosphorus and potassium is highest.
How to Use
- Shake well before use.
- Standard (flush-week) use: Add 1.5 ml per litre of water to your nutrient reservoir for a 3–6 day feed period, ideally around 3 weeks before harvest.
- “Trickle” method: Apply 0.33 ml per litre once buds have formed (approximately week 2–3 of flowering) and continue until final flush for gradual PK support.
- Mixing instructions: Always add PK 13/14 after base nutrients and dilute thoroughly. Never mix concentrates directly.
- Compatibility: Suitable for soil, coco or hydro systems and works with soft or hard water.
Frequently Asked Questions (FAQ)
What is CANNA PK 13/14 and when should I use it?It is a concentrated phosphorus-potassium bloom booster designed for the flowering stage. It is most effective when used as a short-term boost around three weeks before harvest or via low-dose trickle feeding from early bloom.
Can I use PK 13/14 on soil, coco or hydro?
Yes, PK 13/14 is compatible with virtually all growing media and systems, including soil, coco, hydroponics and recirculating setups.
Do I still need a base nutrient?
Yes, PK 13/14 is an additive and should be used alongside a complete base nutrient program for optimal results.
Can I use PK 13/14 throughout the entire flowering stage?
Because it is highly concentrated, full-dose use is usually limited to a short period. For longer use, a lower trickle dose is recommended to avoid overfeeding.
Should I combine PK 13/14 with other bloom boosters?
Avoid using other PK-heavy boosters at the same time to prevent nutrient imbalance or salt buildup.
If you're aiming for bigger, heavier flowers or fruits, richer aroma and sweeter taste and an overall higher-yielding harvest, CANNA PK 13/14 offers an efficient and proven way to push plants beyond standard bloom performance. Used at the right time alongside a solid base nutrient program, it can significantly improve final yield and quality.
