BioNova PK 13-14 (phosphorus + potassium)

Product detailed description

We present BioNova PK 13-14 - the legendary flower booster that has set the standard for supporting flowering worldwide. As the creator of the original formula, BioNova delivers a product growers rely on to achieve massive yields and unrivalled quality. Its secret lies in the perfectly balanced combination of phosphorus (P) and potassium (K) in the purest form, immediately available to plants.

Key features and benefits

• Denser and heavier flowers: supports the formation of firm and compact flowers and fruit with significantly higher weight.
• Food-grade purity: made from food-grade minerals, without ballast salts or heavy metals.
• Immediate absorption: nutrients are immediately available to the root system.
• Universal use: suitable for all types of substrate (soil, coco, hydro, aero) and all growing methods.
• Higher sugar and oil content: improves the production of sugars and essential oils for a higher-quality, sweeter and more aromatic harvest.

The power of phosphorus and potassium during flowering

Phosphorus (P) functions as the plant's main energy station. It is indispensable for energy transfer in cells and plays a crucial role in flower formation.

Potassium (K) is the manager of water balance and nutrient transport. Its most important function during flowering is managing the production and distribution of sugars, which is essential for the development of larger, denser and sweeter fruit.

Dosage and use

Use PK 13-14 from the first week of flowering until the last week before flushing. The product is fully miscible with all BioNova fertilisers and supplements.

Special tip: to support root development, apply 1-2 ml per 10 l of water during the second week of the growth phase.

Foliar spray: in the event of an acute phosphorus or potassium deficiency, mix 2.5-5 ml per 10 l of water and apply to the leaves.

Combinations for maximum synergy

For the best results, combine PK 13-14 with the base fertilisers Soil Supermix, Hydro Supermix or AutoFlower Supermix. Adding the X-cel Booster stimulant will also support quality, flavour and active compound content.

Important warning: increase the P and K dose gradually. A concentration increase that is too rapid may lead to excessive sugar production in some sensitive plants and cause flower or fruit rot.

Frequently asked questions

When is PK 13-14 used?

From the first week of flowering until the last week before flushing, with the dose gradually increasing from 2 ml to 6-10 ml per 10 l of water according to the flowering week.

What should PK 13-14 be combined with?

With your base fertiliser - Soil Supermix, Hydro Supermix or AutoFlower Supermix - and, if required, the X-cel Booster stimulant for higher harvest quality.

Can I increase the dose quickly to get larger flowers?

No. Increase the dose gradually - a P and K increase that is too rapid may cause excessive sugar production and flower or fruit rot in sensitive plants.
