Plagron PK 13/14 0,25l
Plagron PK 13-14 0.25L delivers a concentrated dose of phosphorus and potassium specifically formulated for the flowering stage. This 250 ml bottle yields up to 125 litres of nutrient solution at the recommended 2 ml per litre dilution rate. The formulation contains 13.4% water-soluble P₂O₅ and 14.4% water-soluble K₂O — a ratio designed to promote denser, heavier fruit development. With a neutral pH of 7.1 and a density of 1.28 g/ml, PK 13-14 integrates seamlessly into any feeding programme regardless of substrate type. Try this trial-size bottle from plantandflower.be.
Plagron PK 13-14 0.25L — concentrated PK booster for flowering plants
During the flowering phase, plants require significantly more phosphorus and potassium than their base feed typically provides. Plagron PK 13-14 addresses this demand with a highly concentrated mineral fertiliser that delivers precisely these two macronutrients. The 0.25L bottle serves as an accessible entry point for growers looking to incorporate a dedicated PK booster into their nutrient programme without committing to a larger volume.
Key features
PK 13-14 is engineered for maximum bioavailability and ease of use across all growing systems.
- 13.4% water-soluble phosphorus pentoxide (P₂O₅) drives energy transfer and supports fruit formation at a cellular level
- 14.4% water-soluble potassium oxide (K₂O) strengthens cell walls and improves the plant's water regulation
- Clear, colourless, odourless liquid with zero foaming — fully compatible with drip irrigation systems
Application & dosage
Shake well before use. Add a maximum of 2 ml PK 13-14 per litre of irrigation water (1:500 dilution). Apply this solution at every watering throughout the flowering phase. After mixing, add your Plagron base nutrient until the target EC is reached. The 0.25L bottle is ideal for small-scale grows or for evaluating the product before scaling up.
Grower benefits
The targeted supply of phosphorus and potassium results in measurably denser, firmer and heavier fruit. PK 13-14's neutral pH of 7.1 minimises pH fluctuations in the nutrient solution, simplifying reservoir management. Pair it with Plagron Green Sensation for a comprehensive flowering protocol.
Combinations & alternatives
Complement PK 13-14 with Plagron Sugar Royal to enhance flavour and aromatic compounds, or with Plagron Power Buds to maximise flower volume. Both products are available in matching small formats.

How much nutrient solution does 0.25L of PK 13-14 produce?
At the recommended dosage of 2 ml per litre, a 0.25L bottle produces up to 125 litres of ready-to-use nutrient solution. This is typically sufficient for a small indoor grow through an entire flowering cycle.
What is the pH of Plagron PK 13-14?
PK 13-14 has a pH of 7.1, which is essentially neutral. This means it has minimal impact on the pH of your nutrient solution, making it easy to maintain the optimal pH range for your plants regardless of substrate.
Can PK 13-14 be used alongside Plagron Green Sensation?
PK 13-14 and Green Sensation serve complementary roles in the flowering phase. PK 13-14 provides a targeted phosphorus and potassium boost, while Green Sensation is a broader bloom stimulator. Consult the Plagron grow schedule for correct dosing when combining both products.
Is the 0.25L size suitable for beginners?
The 0.25L format is an excellent starting point. It provides enough product to experience the effects of a PK booster without a large upfront investment. The straightforward dosing of 2 ml per litre makes it easy to apply correctly from the first use.
