Plagron PK 13/14 0,5l
Plagron PK 13-14 0.5L provides a sustained supply of phosphorus and potassium throughout the flowering stage. At the standard dilution of 2 ml per litre, this bottle yields up to 250 litres of nutrient solution — enough to support a mid-sized indoor garden for several weeks. The formulation delivers 13.4% water-soluble P₂O₅ and 14.4% water-soluble K₂O, promoting the development of compact, heavy fruit. Its clear, odourless composition with zero foaming makes it compatible with all irrigation methods. EC value of 155 mS/cm in concentrate. Order at plantandflower.be.
Sustained PK supplementation for flowering — Plagron PK 13-14 0.5L
Consistent phosphorus and potassium availability during flowering is critical for maximising fruit weight and density. Plagron PK 13-14 in the 0.5L format offers a practical balance between volume and convenience, providing enough concentrated fertiliser to cover multiple weeks of regular feeding without the bulk of a larger container.

Key features
The effectiveness of PK 13-14 stems from its high-purity mineral composition, optimised for rapid plant uptake.
- 13.4% water-soluble P₂O₅ fuels ATP production and supports the energy-intensive processes of fruit development
- 14.4% water-soluble K₂O regulates stomatal function and enhances turgor pressure for firmer fruit
- EC of 155 mS/cm in concentrate — factor this into your total nutrient solution EC calculations
Application & dosage
Shake thoroughly before each use. Dissolve a maximum of 2 ml PK 13-14 per litre of water (1:500). Use this solution at every irrigation event during the flowering period. Add PK 13-14 to the water first, then adjust with your Plagron base nutrient to reach the desired total EC. The 0.5L size produces up to 250 litres of finished solution, making it well-suited for medium-scale operations.
Grower benefits
Elevated phosphorus and potassium levels during flowering directly correlate with increased fruit density and overall harvest weight. The product's colourless, odourless and non-foaming characteristics ensure clean operation in drip systems and recirculating setups. Integrate Plagron Sugar Royal 0.5L into your regimen to enhance terpene and flavonoid production.
Combinations & alternatives
For a full-spectrum flowering programme, pair PK 13-14 with Plagron Green Sensation 0.5L and Plagron Power Buds. This combination addresses PK supplementation, bloom stimulation and flower volume in a single coordinated protocol.

How many litres of nutrient solution does the 0.5L bottle produce?
At the recommended dosage of 2 ml per litre of water, a 0.5L bottle of PK 13-14 yields up to 250 litres of nutrient solution. This is generally sufficient for several weeks of flowering in a mid-sized indoor setup.
Does PK 13-14 affect the EC of my nutrient solution?
Yes. PK 13-14 has an EC of 155 mS/cm in its concentrated form. At the recommended dilution, it will raise the EC of your nutrient solution. Always add PK 13-14 first, then adjust with your base nutrient to reach the desired total EC value.
At what point during flowering should I start using PK 13-14?
PK 13-14 is applied throughout the flowering phase at every watering. The exact starting point depends on your growing system and substrate. Refer to the Plagron grow schedule for your specific setup to determine the optimal introduction point.
Is PK 13-14 suitable for hydroponic systems?
PK 13-14 is fully compatible with hydroponic, coco and soil-based systems. Its clear, non-foaming formula dissolves completely in water and will not clog drip emitters or cause issues in recirculating reservoirs.
