PK 13-14 from Plagron is a high-grade mineral fertiliser designed to provide plants with the essential boost of phosphorus and potassium required during the peak of the flowering phase. As plants transition into heavy bloom, their demand for these two primary macronutrients increases significantly. This clean, powerful additive ensures that your crop has a readily available supply of phosphorus for increased root development and flower formation, alongside potassium for water regulation and structural strength. By using this concentrated booster, growers can expect harder, heavier, and more compact fruits and flowers, making it a staple for anyone aiming for a high-performance harvest in soil, coco, or hydroponic systems.
Key Benefits of using Plagron PK 13-14
- Maximises Fruit and Flower Weight: Provides the precise ratio of phosphorus and potassium needed to increase the density and overall mass of your harvest.
- Stimulates Vigorous Bloom: Encourages the plant to produce more flowering sites and ensures those sites develop into high-quality yields.
- Clean Mineral Formula: Being a pure mineral additive, it is immediately absorbable by the plant and will not clog irrigation lines or drippers.
- Versatile Application: Fully compatible with all types of growing mediums, including soil, coco coir, and hydroponic setups.
How to Use Plagron PK 13-14
Dosage: Add a maximum of 2ml of PK 13-14 per 1 litre of water (1:500).
Instructions:
- Shake the bottle well before use.
- Add PK 13-14 to your nutrient solution first, then add your base nutrients such as Plagron Terra Bloom or Plagron Cocos A&B.
- Apply this solution during the peak flowering period (usually from the middle of the bloom phase until the final flush).
- Always monitor your EC levels, as this is a highly concentrated mineral product.
For the best possible results, use PK 13-14 in conjunction with Plagron Sugar Royal to enhance flavour while the PK increases the bulk. If you prefer a 4-in-1 solution that includes PK 13-14 along with enzymes and boosters, consider Plagron Green Sensation.
Can be used in all grow mediums including soil, coco and hydroponics.
Available in 5 litres.
Frequently Asked Questions
When exactly should I start using Plagron PK 13-14?
You should typically begin using PK 13-14 during the mid-flowering stage. This is usually around the 4th or 5th week of bloom, depending on the variety of plant, when the flowers are established and beginning to swell.Can I use PK 13-14 and Green Sensation together?
No, it is not recommended to use both at the same time. Plagron Green Sensation already contains a specific ratio of PK nutrients. Combining them could lead to over-fertilisation and nutrient burn.Does Plagron PK 13-14 affect the pH of my nutrient solution?
Yes, like most mineral fertilisers, PK 13-14 will affect the EC and can influence the pH of your reservoir. It is essential to check and adjust your pH levels after adding all your nutrients and additives to the water. Head to pH Management for all your EC and pH needs.Is PK 13-14 suitable for use in hydroponic systems?
Absolutely. Because it is a highly refined mineral product, it dissolves completely in water and is perfect for use in NFT, DWC, and other hydroponic systems without the risk of blocking pumps or pipes.SKU: 1844 Free delivery on orders over £60*
